Eliminate Glare in Reflective Surfaces

You've probably felt the frustration of trying to take a picture of a reflective object, such as a framed painting, and getting glare. The secret is to add another flash.

 

Using two external flashes instead of your camera's built-in unit offers all sorts of new photographic possibilities. You can produce great-looking portraiture with just a couple electronic flashes and light stands. Here's another use for this capability: photographing reflective surfaces without producing glare.

 

As you know, when you try to use your camera's built-in flash to take a flash picture of, let's say, a painting on the wall, you always get a hot spot somewhere in the image. You could turn off the flash, lug everything outside, and then use natural light, but that's not always convenient either, such as when it's night. Plus, if you're shooting a lot of different objects to sell on eBay, do you really want to be standing outside with your equipment all day?

Try this method instead and work comfortably indoors. Hang your artwork on the wall and get your flashes and light stands together. For this assignment, you won't need the photo umbrella, but you will need both the flashes mounted on their light stands.

 

Raise the light stands so that the flashes are the same height as the painting, Now position one on the left and one on the right, each at 45° angles from the painting. The flashes and painting should form a triangle.

 

Mount your camera on a tripod and extend the legs so that the camera is the same height as the center of the painting. Make sure the camera is level and centered between the two flashes. Now, focus and take a picture.

 

Both flashes will go off, but amazingly, there's no light reflection in the picture! Magically, each flash cancels out the reflection from the other. You get an evenly illuminated image with no hot spots.

 

 

Place your camera so that the camera is the same height as the center of the subject and centered between the two flashes. Focus and take a picture. There’s no light reflection because each flash cancels out the reflection from the other.

 

You can also apply this technique to tabletop photography for items such as flower vases and glassware. The main thing to remember is to keep your light sources at strict 45° angles from the subject, and keep the camera centered between them.

Pro Portraits with Just Two Flashes

You don't need to spend thousands of dollars on expensive lighting to get professional-looking portraits.

Many amateur photographers are intimidated by studio portraiture, and for good reason. A trip to a working pro's studio reveals thousands of dollars of lighting equipment, specialized backdrops, and various posing accessories. Who can afford that?

You have to remember that working pros need all that stuff because they're required to meet the needs of a various clients. Pros often don't know who's going to walk in the door and what that person is going to want. You don't have that problem. Your mortgage isn't dependent on your ability to meet every customer's whim.

So, then, how much stuff do you need to shoot a professional-looking portrait? Your setup can be as simple as two flashes, two light stands, one photo umbrella, and a nontextured backdrop, such as butcher's paper. All of these goodies fit easily in the trunk of your car, enabling you to shoot great-looking portraits just about anywhere.

Get Your Lighting Together

For this assignment, I'm going to start by showing you what I consider the easiest way to go. Even though the investment in this equipment is far less than what pros spend, the bottom line might still be more than your budget allows (figure about US$600). If this is the case for you, I'll present some low-cost alternatives at the end of this hack. But let's start with the most desirable and go from there.

 

First, I strongly recommend a camera that has Manual Exposure control and accepts external flashes. A camera that has lots of flash accessories available from the manufacturer is even better. At the moment, Nikon and Canon provide the most options.When you're shopping for external flashes, look for models that can be triggered wirelessly by the camera. These units are perfect for the photographer on the go. The transmitter mounts in the camera's hot shoe and wirelessly triggers all the flashes when you trip the shutter.

 

Not only does this configuration save you from the tangle of wires, but the flash units and camera also communicate during the exposure, so you get perfectly exposed shots without having to calculate guide numbers and f-stops. It's truly amazing. Nikon's offering is equally fantastic.

Now, all you need are a couple of light stands (with brackets) on which to mount your flashes and a photo umbrella to serve as a diffuser for the main light. I've had good luck with Bogen light stands, such as model 3097, because they provide good height but fold down to a compact size and are lightweight. I add a Bogen 028 flash bracket to the top of each stand so that I can position the light at any angle. Plus, I use these brackets to hold the umbrella. Just about any type of photo umbrella will serve you well, so shop for price.
