Night Landscapes and the Moon

The moon is a beautiful but often elusive element for nighttime landscapes. If your previous attempts have resulted in sheer lunacy, take a look at these helpful tips.

 

Nothing perks up an evening landscape like a rising moon hanging above the horizon. You walk out of the office to go home. It's dusk and there's still color in the sky. Then, like magic, the moon appears from behind the clouds. You feel like you can reach out and touch it, just like that. These are the small moments that often stay with us.

 

Trying to photograph that is another matter. The moon hanging just above the horizon looked so big. But it seems to shrink in size the minute you point a camera lens at it. What was once a compelling evening moonscape photographs as a bunch of clouds with an overexposed dot of light among them.

 

Don't despair. By making a few adjustments to how you take the shots and applying a little photographic wizardry, you can bring the moon back to its rightful splendor. But to do so you have to overcome a few common obstacles.

 

Obstacle: The Moon Is Brighter Than Everything Else

If you wait until the sky is completely dark and the moon is high above the horizon, chances are the moon is brighter than everything else in the scene. The trick here is to catch the moon when it's low and to include other bright things in the composition. When the moon is lower, it shines through more atmosphere than when it is high in the sky. The atmosphere serves as a neutral density filter of sorts and reduces the moon's luminosity.

 

However, if everything else in the frame is dark, then your camera will expose for the dominating dark elements and thereby overexpose the moon, rendering it as a fuzzy dot of light. Look for adjacent elements to lighten up the scene, such as brightly lit buildings (their lights often go on at dusk, before darkness sets in), illuminated clouds from the setting sun, or any other radiant element.

 

You will have to experiment with your exposure times as so many elements will affect the outcome. The degree of available moonlight; any other light sources; clouds; rain; light reflective surfaces; each of them can make a huge difference to the amount of exposure time needed.

In general, during night photography, one can say that on a night of full moon, with optimum conditions, 8 seconds at f/8 using ISO 100 film will be about right. If there’s a crescent moon and conditions are also optimal, you would need as much as 10 hours on one shot! So you see experimentation while photographing the moon is really the only way to go.

Light Painting and Colored Gels

With an inexpensive swatch book of theater lighting gels, some night tlight bulbs, and a couple of LED flashlights, you can create the real color effects. And the best part is that you don't need Photoshop or even a computer.

Yes, you can manipulate photos in just about every way imaginable in Photoshop. But what if you don't like Photoshop, don't feel that comfortable with your image-editing skills, or just want to try something new? Alternatively, you can manipulate the picture as you actually capture it with the camera. Working with light painting and colored gels,is a great way to experiment with this type of creative shooting.

Crystal with colored gel

I use quartz crystals for my example because they're fun to manipulate with light, but just about any translucent or reflective subject has potential. My tools include theater lighting gels, nightlights, a photographer's light box, colored bulbs, and LED flashlights. One of my favorite combinations for experimentation is a regular nightlight bulb shining through Roscolux theater gels. For US$3.50 at Rose's Theatrical Supply, you can get a Roscolux Swatch Book that contains a sample of every gel in their collection.


Light_painting_and_colored_gels

 

For the crystal shots, I made a custom light stand out of a six-inch length of 2" 4" wood. I simply drilled two holes? one downward from the top and one inward from the side? to form an L-shaped opening in the wood. The crystal sits on the top hole, and the nightlight bulb goes in the side hole. Now, I can put any color gel I want over the top hole, and that will be the color of light projected up through the crystal.

 

When you use this setup in a darkened room, the colored light shining up through the crystal is subtle and quite striking. If you want, while the shutter is open, you can add more effects, such as light painting. This is why nightlight bulbs, which are typically only four watts or so, are good for this type of project. The dim light creates long exposures that give you the opportunity to paint with other lights, such as flashlights with colored bulbs, while the shutter is open.


Many of the new LED pocket lights that are available for US$10 or less have options for red, green, blue, and white bulbs. You can shop around at flashlight specialty shops, to discover a whole new universe of creative lighting options. And when you're not painting with them, they make great additions to your keychain.

 

The Set up:

Find a work area where you can control the ambient lighting. Set up your prop lighting (such as the light stand I discussed earlier), colored gels, and subject. Mount your camera on a sturdy tripod. You can use Auto Exposure mode, but check you camera manual for how long the shutter will stay open with that setting. Some cameras have a Long Exposure mode; if yours does, you should use it.

 

Most advanced cameras have Shutter Priority mode, which makes this work easier. You can set the shutter speed to three or four seconds, and the camera will handle the aperture settings for you. As you work, you'll have to lengthen the shutter exposure (such as 6, 8, or 10 seconds) to lighten the picture, or shorten the exposure (2 seconds or less) to darken it. Play with your settings until you get the effect you want.

 

I like to use a remote release to trip the shutter, but if you don't have a remote, you can also use the self-timer. The main thing is that you don't want to jar the camera when you initiate the exposure. Even the slightest vibration during exposure will degrade your image. Speaking of picture quality, set the ISO on its lowest rating: 50 or 100. This ISO will produce nice, long exposures under these dim lighting conditions, giving you more time to play while the shutter is open.

 

Now, dim the room lights and let your imagination run wild. Take the colored bulbs or flashlights and move them around in the scene while the shutter is open. You'll find that different speeds and angles create different types of brush strokes.

Starlight Effects for Candles and Lights

Add extra sparkle to your candle and chandelier images by using an inexpensive starlight filter. You can even make your own, if you don't mind scratching a little glass.

 

Candlelit rooms convey a romantic or sentimental mood for your images. All you have to do is steady the camera, trip the shutter, and play from there.The thing with candles, however, is that the light they cast on your subject is often more interesting than the candles themselves. After all, how compelling is a little flame of light? You can add a little oomph to these images by using a star-effect filter, which takes a normal candle flame and turns it into a blazing star.

 

Candle flame without and with a star filter       

Candle_flame_without_and_with_a_star_filter

This little bit of photographic trickery is accomplished by tiny etches in the glass that distort the light. If your camera accepts filters, you can pony up US$25 and start to play right away. One brand of creative filters you might want to take a look at is the Cokin System, which has star effects, gradual density, and special-effect filters  Cokin has adapters for every type of camera and lens, and it even has a special mount for cameras that don't even have filter rings, such as your digital point and shoot. I've played with the Cokin Star Effect, A Version, and have had good success, even on a Canon Digital Elph S400, which doesn't have a filter ring.

Shooting Technique

I tend to like the effect of these filters when the light source is smaller, such as the Christmas lights. I've noticed quite an improvement after I trim the candle wick, thereby reducing the size of the flame. Points of light produce sharp rays of light, emanating from the source. Larger light sources, such as a light bulb or untrimmed candle wick, produce softer, less detailed effects. Chandeliers can be quite impressive too.


I've had the best luck mounting the camera on a tripod and using the self-timer to trip the shutter. This helps me avoid the blurring effects of camera shake. Usually, I find that if I use -1 or -2 on the Exposure Compensation dial for close-up shots, I get better rays of light. Experiment until you get the effect you want. Rows of candles shot with a star filter can be impressive. The room is transformed into a magical place, part of some other reality? Not bad for an old UV filter with a few etched scratches in it!

Auto Headlamps and Other Streaming Lights

You can energize your night shots by including streaming lights, such as cars passing through your composition. Just make sure you're not standing in the flow of traffic at the time.

The flow of traffic provides a great opportunity to add motion to your compositions. Automobiles are light-painting machines, and it's easy to put them to work for you. The key to success is to find a location with ambient light? such as a well-lit street, a bridge, or a large building? to serve as your main composition. Yes, you can go stand out on a dark highway and photograph cars as they whiz by, but images of streaming lights against a pitch-black backdrop aren't really worth the danger of being there in the first place.

Think of streaming lights as an element that you add to an already interesting composition, not the sole subject of the picture itself. If you were shooting a quiet little neighborhood, you probably wouldn't add this element to the shot; you're trying to convey solitude, comfort, and a feeling of being off the beaten track. But if you wanted to show the hustle and bustle of rush-hour traffic on the Golden Gate Bridge or in Manhattan, including lots of streaming lights adds a sense of energy and activity. Featuring the Empire State Building rising above the activity on the street. By including streaming car lights as they drive by, you get a feel for the energy of New York City.

Your Equipment

The first thing you need to do is find your tripod. This type of photography requires exposures that are too long for even the steadiest of hands. If you don't want to lug around your big three-legged beast, buy a handy pocket tripod that you can set on top of newspaper boxes and ledges.

If your camera accepts a remote release, use it. Not only do you need it to trip the shutter without jarring the camera, but you also want to start the exposure just as cars are driving by. You can also use the self-timer, but you won't have nearly as much control over when the exposure begins.

Photography Tips: Take Flash Shots of People Who Blink

Every family has one: the person whose eyes are closed every time you use the flash to take a picture. Here's how to get those eyes open.

 

Some of the most beautiful people take the worst photographs, especially if the flash is turned on. It's almost like they have a sixth sense as to when the flash is going to fire and, in defense of their sensitive eyes, they close their lids.

 

For years, I struggled to find an answer to this problem. Then, one day, by accident, the solution appeared. And, of all things, the secret is that otherwise silly function: Red Eye Reduction mode. That's right; the very flash mode that I've decided in pervious parts of this book is the shining savior for blinkers. Here's how it works.

 

The idea behind Red Eye Reduction mode is to shine a light, or a series of light bursts, into the subject's eyes, causing the iris to constrict and thereby reducing the chances of red eye.

It really doesn't work that well. But for people who are sensitive to the flash and close their eyes when it fires, Red Eye Reduction mode is a godsend.

 

This mode causes them to blink during the pre-shot flashes. Then, when the actual picture is taken, they've opened their eyes. True, this is an extreme measure, because you still lose spontaneity as Red Eye Reduction mode does its thing, but as a last-ditch effort for those people whom you just can't capture with their eyes open, this trick can save your night.

< Day

We recommend different resolution settings for text and images. Scans should be produced at 600 to 1,200 dots per inch (dpi) at reproduction size for text and line art and at 300 dpi for continuous tone images. Increasing the resolution has minimal impact on continuous tone images. To determine resolution of existing images when scaled to planned reproduction size, Adobe Photoshop has an “image size” tool in its pull-down menu that can automatically calculate resolution at various sizes.

 

While digital color presses are excellent at reproducing color, they perform less well in reproducing large areas of some colors evenly — especially mid-tone tints and long blends. Often they come out fine, but sometimes they show unevenness.

 

Reproduction can be improved by choosing a lighter or darker percentage or using imaging software, such as Adobe Photoshop, to add “noise,” or texture, or to create a tight pattern. Thorough proofing helps ensure that the approach is working.

Capture the Nighttime Mood and Leave the Red Eye at Home

Shooting with flash indoors against a dark, boring background often produces overexposed subjects with red eye. But it doesn't have to be that way.

 

Built-in camera flashes are very convenient. But they can produce deadly results when used to take pictures of people in low-light situations, such as evening parties. Aside from the plague of red eye that turns your loved ones into otherworldly demons, there's also the nuclear look? Where the subject appears to be standing next to ground zero, glowing beyond recognition

 

It doesn't have to be that way. The easiest way to increase your success rate is to get an external flash; it's just easier to control the lighting that way. But for many people, that's not practical. So, in this hack we'll look at the options for the portable digicam, and then talk about more advanced techniques with external flash. Let's start with taming the pocketable point and shoot.

 

Pocketable Party Shots

The people who design compact dig-cams realize that these cameras don't always produce great flash results at night. So, many of today's models have features designed to help you get better shots in these challenging situations. Some of these features work better than others. Here's a quick overview of what to look for and what to avoid:

 

Red Eye Reduction mode

Avoid using this setting. In theory, using Red Eye Reduction mode makes sense: shine a bright light in the subject's eyes before exposure to constrict the iris, thereby reducing the chance of reflected red eye. But it doesn't work out that way. Flashes are annoying anyway, and torturing your subject with additional flash before taking the shot tends to kill spontaneity. Plus, even after you do that, you'll often still get red eye. It's just not worth it.

 

Nighttime Flash mode

Use this setting for artistic shots. At times, using this mode might feel like trying to tame a wild cat: you think you're making progress, then it gets away from you. The thinking here is that the camera slows down the shutter speed, allowing you to capture background scenery beyond the flash range, yet the flash still goes off, illuminating subjects within 10 feet. And it usually works quite well. But things get crazy if you don't hold the camera really steady or if there's a lot of movement in the scene. So, you'll get some absolutely great shots with artistic flair, and you'll get some failures. But it's definitely worth experimenting with. This control is also referred to as Slow Synchro Flash mode.

Street Photography Shooting at Night

Because of their compact size, pocket digicams are excellent street-shooters, enabling you to capture the grit and the glory of urban life at night? that is, if you know how.

 

When you sit back and look at your travel shots, do you ever feel like you're shooting the same thing over and over, and only the locations change (same boring group shots, blurry bus scenes through the window, and yet another statue)? One of the best ways to inject life into your photography is to grab your camera and hit the streets...on foot.

Now, I'm not talking about raw photojournalism or anything dangerous. Every major city in the civilized world has a good part of town and a bad one. Lace up your sneakers and go to the friendly part of town.


My favorite time to shoot on the streets is from about an hour before twilight until darkness.Generally speaking, there's lots of activity at this time, and the building lights come on when there is still some color left in the sky. It's a magical setting that's perfect for night photography.

 

But if you want to capture that magic, you have to turn off your flash. This is rule number one for interesting street photography. Not only does the flash draw way too much attention to your shooting, but it also kills the shots. The possible exception is using Nighttime Flash mode, but for most of your street shooting, leave the flash off.

 

The best time for "night" photography is actually twilight. Most city lights come on before complete darkness. Your shots will be much more colorful and compelling with the deep blue twilight sky rather than the blackness of night, as shown in the two pictures of the Chrysler Building. The first picture was shot late at night, when the sky was completely dark. I went back the next day at dusk and captured the second shot with more color in the sky. Which do you like best?       


As the light goes down, however, your exposures will get longer, which means you have to look out for camera shake. Here are a few ways to combat shake so you get crisp images, even in low light:

 

Stret_photography

· Increase your ISO setting from 100 to 200

You can go up to 400 if you need to, but you will have more noise in your shots at the higher rating. Often, this isn't a big problem for street shooting, because the gritty look seems to work with this type of subject material. Generally speaking, though, don't increase your ISO setting any more than you have to.

Night Photography: Nighttime Portraits with Scenic Backgrounds

Sometimes, capturing the background of a nighttime portrait as just as important as capturing the subject itself.

 

Long ago, in a distant place, a camera designer made the decision to set the shutter speed to 1/60 of a second when the flash is activated. I don't know exactly when this happened, but that's the way it's been ever since I can remember.

 

The problem with 1/60 of a second is that it often creates night flash shots with muddy o nonexistent backgrounds. To prove my point, find a vibrant night scene, such as a street composition in New Orleans's French Quarter, turn off your flash, and take a meter reading. I doubt that the shutter speed will be 1/60 of a second. Most likely, you will get a reading of 1/30, 1/15, or slower. Brightly lit night scenes usually require that the shutter stay open longer than in brightly lit daytime scenes. Have you noticed that your daytime fill-flash shots look better than your nighttime flash shots? It all comes down to shutter speed.

 

When it comes to flash photography at night, shutter speed controls the appearance of the background and aperture controls the exposure of the subject within flash range. If the background doesn't look the way you want, change the shutter speed. If the subject within flash range doesn't look right, change the aperture.

 

If you leave your camera in auto-everything mode, it sets the shutter to 1/60 of a second when you turn on the flash. This is a safe shutter speed that provides acceptable images in a variety of lighting situations, both daytime and nighttime. But if you're in New Orleans having the time of your life, acceptable isn't going to cut it.

 

Night_photography

 

Here's what you have to do: slow down the shutter speed when the flash is on. Almost every camera gives you some way to do this. Here's what to look for:

 

Nighttime Flash mode

Cycle through your flash settings and look for the icon of a subject with a star overhead. If you have this icon, kiss your camera and the person who bought it for you. Under this setting, the camera will read the background, choose the right shutter speed, and add enough flash for the subject. When it works right, both the background and subject are nicely exposed.

 

Shutter Priority mode

Typically, this setting is reserved for more advanced cameras. Often, Shutter Priority mode is indicated by an S. Other times, it's indicated by TV, for Time Value. Either way, you get to set the shutter speed, and the camera then automatically adjusts the aperture and adds the right amount of flash.

 

Long Shutter mode

If your camera doesn't have Shutter Priority mode, it might have an abbreviated version called Long Shutter. This mode allows the user to slow down the shutter speed for situations such as night photography. The camera will do its best to add the right amount of flash and set the correct aperture.

 

Manual mode

You'll see this setting more often on advanced cameras. Manual mode enables you to set both the shutter speed and the aperture. The camera adds the right amount of flash.

Analyze Metadata to Improve Your Photography Shots

In the days of film cameras, I seldom recorded exposure settings that would have helped me better analyze my pictures. Now, digital cameras handle all that work for me, and I can use that information to figure out what went right or what went wrong.

 

Every time you click the shutter, your digital camera records valuable picture data that describes the image you just captured. Data such as time, shutter speed, aperture, focal length, and ISO are written to the file header in the Exchangeable Image File (EXIF) format. This information becomes part of the total image file and can be displayed with applications such as Photoshop.

 

In essence, each picture file contains a complete photographic history of the decisive moment, which can be analyzed to help you understand why the image was successful or give you clues as to what went wrong. In this hack, I'll show you how to retrieve this data and use it to perfect your photography portfolio skills.

 

What Is EXIF?

The EXIF format is an international specification, first established in 1995, that enables digital cameras (and other imaging devices) to write data to the file header of the image. EXIF files use the JPEG DCT format specified in ISO/IEC 10918-1. The picture portion of the file can be read by any application supporting JPEG, including web browsers and image editors. The metadata can be accessed by applications designed to extract that information out of the header and display it. The most common imaging applications have no problem displaying at least some of the EXIF data.

 

However, the picture file usually contains more information than what's typically displayed by a given application, unless that application is designed specifically to output EXIF information. For example, iPhoto on the Mac provides the basic time, date, file size, and camera information when you click on the Photo tab of the Show Info window. If you click on the Exposure tab, you get more data, such as shutter speed, aperture, focal length, exposure compensation, metering pattern, and flash status.

 

But iPhoto doesn't provide you with other data sitting there in the file header, such as whit balance. If you need that information, you have to open the file with another application designed to grab that data. The point is that the EXIF specification dictates what goes in to the picture file, but image editors typically give you only a portion of that information. So, if you get serious about reading this stuff, you might need to add a couple tools to your imaging bag of tricks.


Exif_and_beyond_sq

 

Why Would I Want to Read EXIF Data?

When you take pictures, some turn out better than others. Why is that? Beyond good composition and subject matter, there are many factors that contribute to powerful images. These include time of day, depth of field, proper shutter speed, and exposure compensation as needed.

 

If you look at a picture of running water, for example, and you like the way it's rendered, wouldn't it be nice to know the settings that you used, so you could duplicate the effect? Before digital cameras were available, I would take handwritten notes to help me remember the settings for particular shots. I hated that! Now, the camera records all that information for me, and I'm free to concentrate on taking good pictures.

 

I know that I can control the way water appears by adjusting the shutter speed. The 1/250-of-a-second exposure "stopped the action" to some degree and the 1-second exposure created a soft look. Now, the next time I shoot running water, I can capture the exact effect I want by adjusting the shutter speed.

Create Soft Background Portraits

Do professional portrait photographers use special lenses and accessories to soften the backgrounds in their portraits? No, they don't. They manipulate the depth of field, and this hack will show you how.

 

The previous hack showed how to create tremendous depth of field for landscape compositions. But when you're shooting portraits outdoors, this is usually the last thing you want. For these types of assignments, you want your viewer's attention locked in on the subject, not the background. The best way to accomplish this is to narrow your depth of field and focus your camera directly on the subject's eyes.

 

Why Soft Backgrounds?

When everything works right, the result is a dreamy, soft backdrop that makes your model pop forward, attracting all attention to her presence. Generally speaking, the first thing viewers look at in a portrait is the subject's eyes. The easier you make it for them to get to that spot, the happier they will be, at least subconsciously. Once they've viewed the eyes, they examine other aspects of the person until they're satisfied and move on. To get a soft portrait background, try to get some distance between the subject and the backdrop. Then, open your aperture to limit the depth of field.

 

Soft_portrait

 

Distracting background elements, such as a tree growing out of the top of the subject's head, is unsettling to the viewer. That's why you often want to eliminate or at least soften these elements.

 

Now remember, this is not a technique that you'll use every time you shoot a portrait. If, for example, you're shooting a baseball owner standing in his stadium, you might want the background elements distinguishable, because that tells a better story. So, soft-background portraiture is a technique to use only when appropriate for the assignment.

 

Here’s a tip for creating a soft background for your portrait: Use a telephoto lens

Learn Photography: Create the Maximum Depth of Field

Imagine the kind of pictures you could take if everything were in focus from one foot to infinity? Here's the inside scoop on one of the oldest secrets in photography.

Galen Rowell, one of my favorite photographers, used to create landscape compositions in which both foreground objects and distant elements appeared in perfect focus. The effect is stunning. The viewer can both study a delicate pattern of petals in a foreground flower and marvel at the beauty of outlying mountains. How did he do that?

Galen found a way to capture tremendous depth of field in his images. In other words, he could have everything in focus, from inches away to infinity. You can employ this same technique in your photography; you just have to know the hack. Three important factors come into play on these types of shots:

The focal length of your lens: The wider the better

The lens aperture: The smaller the better (f-16, f-22, etc.)

The object on which you focus in the composition: Contrary to expectation, it's not the thing closest to you.

Once you've properly set these adjustments, you can create depth of field that spans from a foot in front of you to the puffy clouds drifting by.

 

2.12.1 Focal Length: The Wider the Better

Wide-angle lenses, or zoom lenses set to wide angle, are a key factor in depth-of-field photography. They help create the illusion that more things are in focus. Galen Rowell usually shot with 35mm film cameras, and often he would use a 24mm wide-angle lens for this type of landscape image. For this hack, I recommend you find a digital lens that provides a film-camera equivalent of a 28mm lens. You can go wider if you want (such as 24mm), but as you'll see, that's easier said than done in the digital world.

For example, if you're shooting with an SLR, such as a Nikon D70, then you would need to use Nikon's 17-55mm zoom lens to get roughly the same angle of view as Galen's 24mm lens on his 35mm SLR.

Why? Well, the D70 and many other digital SLRs have image sensors that are smaller than 35mm film. That changes the relationship between lens and camera, and the result is that you often have to multiply the focal length of the lens by a factor of 1.5 to get the same angle of coverage that you would with the lens mounted on a film camera.

If you multiply the Nikon 17-55mm zoom lens by 1.5, you get the 35mm equivalent of a

25.5-82.5mm lens. You may or may not care about all of this. But what you do need to know is that you have to find a lens with a film-camera equivalent of at least a 28mm lens for this type of photography. The Nikon 17-55mm zoom on a D70 should work nicely.

If you're shooting with a digital point and shoot, such as a Canon PowerShot A80, then your built-in zoom lens (7.8-23.4mm) has the film-camera equivalent of a 38-114mm zoom lens? not quite as wide as we'd like for this type of shooting. The good news is that Canon offers a wide converter (WC-DC52) for this camera that attaches over the built-in zoom lens. It extends your field of view to a healthy film-camera equivalent 24mm lens. Cool! In fact, many digital point and shoots accept wide-angle lens attachments. If you're interested in this type of shooting, then you'll want to make sure your next camera has this.

Painless Infrared Photography

What kind of eerie world makes the sky go dark and trees turn white? It's the stunningly beautiful realm of infrared photography.


If you've ever tried shooting and processing infrared film, you know what a pain in the aperture it is to deal with. You have to load the camera in complete darkness, guess wildly about the exposure settings, process the film, and then cross your fingers that at least one or two shots turned out the way you had hoped. The results could be stunning, but they came at a painful price.

 

Digital photography has changed all that. Not only is persnickety film handling a thing of the past, but you also now get to preview your infrared images on the LCD monitor before taking the shot. And the best part; they will look every bit as beautiful as their film counterparts, as you can see in image which was shot with a Canon G1 digital camera. This barn shot was taken at 1 p.m. Most photographers are diving for cover at this time of day? That is, unless they're shooting infrared.


Infrared

 

Infrared photography deals with the spectrum of light that you can't see but that your digital camera can. If you buy a filter to eliminate the normal light rays and capture only the infrared rays, you can add this look to your photographic bag of tricks.

 

The first thing you'll notice in infrared photography is that the blue sky goes dark and that most trees turn very light. Glare is minimized, giving your pictures an eerie clarity. A popular filter for digi-cam infrared photography is the Hoya R72. If your camera accepts filters, then go get an R72 at the camera store, attach it to your camera, and look at a brightly lit scene in the LCD viewfinder. You'll know right away if your camera is suitable for this kind of shooting. You can test the "infraredness" of your camera by pointing a remote control toward the lens and seeing if the beam registers the camera's LCD monitor.

Stylish Photography: Multiple Exposures, Digital Style

If you're looking for the multiple-exposures setting on your digicam, forget about it. It probably isn't there, unless you own a Fuji pro SLR camera or one of a handful of other models with this capability. So, what's the creative digital photographer to do?

 

In the film world, multiple exposures are a great way to create interesting, unexpected visual effects. Traditionally, this was done either in-camera by exposing one frame of film many times or in the darkroom by sandwiching negatives together.

Unfortunately, most digital cameras don't support multiple exposures. But that doesn't mean it can't be done. Photoshop, the digital darkroom of choice for many, comes to the rescue.

 

There are a couple ways to approach gathering your source material for Photoshop. You can previsualize the final image you're after, shoot its parts (layers) with your digital camera, and then assemble these layers on the computer. Or, if you just want to experiment, grab a few pictures out of your existing library, mush them together, and see what happens. Suddenly, every digital image in your photo library becomes potential fodder for an interesting photo montage.

As you shoot, try to imagine each shot layered on top of the next one, resulting in an interesting image. For each shot, we're going to underexpose by a factor of 2. Set your exposure compensation to -2 and take three different shots. You've now captured three underexposed images that, when added together, will create one well-exposed image.

Bring these pictures into your computer, start up Photoshop, and open each one in turn. Copy two of the images and paste them into the first. You should now have a single image file with three layers. If you open the Layers palette (Window Layers), you'll see

Photography: Make Your Own Passport Photo

Don't spend money for a terrible passport picture that you'll be embarrassed to show to strangers all over the world. You can take your own shot, and make great first impressions instead.

 

 

Why is it that whenever you have an official photograph taken, you're made to look like a  criminal or terrorist? Sometimes, you don't have a choice in the matter, such as for your  

driver's license (or booking at the county jail). But when it comes to passport photos, you 

can submit your own picture, and I recommend you do.

There are general requirements for an acceptable photo:

· Photographs must be identical and recent (within six months), with a clear full-face  and front-view image. They may be in color or     black       and white.

· The photographs must be at least 2" 2" (5cm 5cm), exclusive of any white borders. The image size, from the bottom of the chin to the top of    the    head (including hair), should measure between one inch and one and three-eighth's inches. There should be at least one half inch    between the      top of the head and the photograph's border.

· There must be a clear contrast between the background and the image of the subject. The background of the photographs must be white.      Grainy   photographs cannot be accepted.

Easy enough, right? Now let's talk about actually taking the picture, because that's the important part. Here is the equipment you'll need:

· Digital camera with a self-timer or remote release

· Tripod or alternative way to position the camera

· Two pieces of white foamcore, cardboard, or some other sturdy, reflective surface

· A stool or something else to sit on

· Inkjet printer with photo paper, preferably with matte surface

You want to avoid that stark, deer-in-the-headlights appearance that's usually caused by using a single flash in darkened room. You might still use a flash for your shot, but if so, it should be a fill flash and not the sole source of illumination. 

Look for a well-lit area that has a white or light background. You might use a brightly lit room in the house (with lots of light coming through one or more windows) or an outdoor setting, where you can use the side of the house for the background. But you don't want the sun shining right in your eyes. Diffused light is better.

Position your sitting stool at least five feet away from the background. You don't want to record much background detail. Instead, you want the background a little out of focus, and distance is the best way to create that effect.

Put the camera on the tripod and point it at the sitting stool. A trick I like to do is to put a lamp on the stool to act as my model while I'm aligning the camera. If you have a helper for this project, that person can serve as your stand-in. Position the camera slightly above eye level of the subject. By doing so, the picture will be more flattering and, if you do use a fill light, the shadows will be cast downward and out of the picture.

For your first test shot, turn off the flash. Let's see how it looks with natural light only. Turn on the self-timer, have a seat, smile slightly, and hold still until the camera has recorded the image. How does it look? If one side of your face is too shadowy, then position one of the pieces of white foamcore so it reflects light onto the dark side of your face.

Secrets of Whiteboard Photography

Never rewrite anything you can digitize. If you've ever been tasked with copying a full whiteboard after an intense brainstorming session, you know what I mean.

You've just finished participating in one of the most amazing brainstorming sessions of your career. The massive whiteboard, which covers an entire wall of the conference room, is covered with words, arrows, and diagrams. You're about to rush from the room to begin putting these plans into action when your boss says to you, "Robertson! Would you please copy down these notes and circulate them to everyone who attended the meeting?"

Copy those notes?! Not even Leonardo Da Vinci could reproduce those drawings. Suddenly, an air of calm comes over you as you recall "Secrets of Whiteboard Photography" from Digital Photography Hacks. You pull your digital camera out from your backpack and go to work. Why rewrite something that's already been written, when you can photograph it, save it as a .jpg file, and circulate it to anyone with a browser on their computer?

This hack will make more sense to you if you first understand how a camera sees the world. Most cameras are calibrated for capturing blue skies, green grass, and other middle tones. And, more often than not, your camera will try to convert anything on the extreme end of the exposure scale to those same middle tones. So the black cat becomes gray and the whiteboard becomes a murky beige color. So, job number one is to find your exposure compensation adjustment and set it to +1. That will tell your camera to overexpose the subject and make the whiteboard white, not gray. Then, turn up the room lights, open the shades, and turn off your camera's built-in flash. Those little strobes might be fine for blinding your best friend at her birthday party, but they're not so good for shooting whiteboards? unless, that is, you don't care about reading the writing. Flashes tend to nuke white shiny surfaces.

Now, take a test shot like the one shown in Figure. How do the colors look? Some cameras have excellent auto white balance settings and will compensate for most lighting situations. If the color looks off, you might want to override the auto setting.

Tame whiteboard madness by taking a picture, not by rewriting.

Photography Ideas: Get the Big Picture with a Panorama

They say two heads are better than one. When it comes to showing the "big picture," many heads? er, shots? are definitely bigger than one.

 

Many people are frustrated by their inability to capture the majesty of awesome natural monuments such as the Grand Canyon. I've heard this phrase a dozen times: "This picture doesn't really do it justice. It looked so fantastic when I was there." Bad photography isn't the culprit here; inadequate coverage is.

 

Let me ask you this: if you went to the Grand Canyon and had to look at it through a toilet-paper tube, how impressive would you think it was? Probably not much, the same thing happens when you try to capture the magnificence of a vast location with single shots on your point and shoot. This doesn't mean that you have to go out and buy a camera with a super-wide lens. Instead, put the magic of digital photography to work for you.

 

Almost every digital camera available today is capable of creating breathtaking panoramas by stitching together a series of shots into one gigantic, seamless scene. Back in the days of film, you probably played around with this technique by taping together snapshots to make a bigger picture. One of my favorite artists, David Hockney, put a creative spin on this technique with works such as "The Brooklyn Bridge Nov 28th 1982" and "Pear blossom Hwy. Hockney's works are usually referred to as photographic collages. But the concept is similar to our exploration here? Taking a bunch of small images and combining them to make a big picture.

 

Unlike Hockney's work, however, our panoramas are very linear, moving from left to right. If your camera has a Panorama mode, use it; it helps you capture the images in a way that's easier for your computer to deal with later. That's the process. You shoot 3 to 12 pictures, moving from left to right, and then upload them to your computer where they can be stitched together as a sweeping vista.

 

Let's start with the shooting technique. You'll get the best results if you use a tripod, and you'll have even better luck if you have a bubble level to go with it. That way, you can align your camera to keep a straight horizon line through the entire picture-taking sequence. If your tripod doesn't have a built-in level, go to the camera store to buy one that attaches to your camera's hot shoe.

 

Look for a location with the sun to your back. Most panoramas cover about 180°. You want the lighting as even as possible on that scene so that you don't have abrupt shifts in the color of the sky, which makes it more difficult to stitch together the scene and end up with continuous tones. Once you have your camera mounted and aligned, swing through the scene and follow the horizon line to make sure it stays level.

 

If your camera has a Panorama mode, enable it. Otherwise, just make sure you overlap one third of the frame as you move from shot to shot. This will give your computer lots of information to stitch the scenes together.
