Eliminating Reflections from Glasses
I know of a photographer who has been accused of popping the lenses out of eyeglasses to avoid having to deal with reflections in photographs. This might be fine in bizarro world, but the rest of us need to deal with reflections in eyeglasses the old fashioned way: first by avoiding reflections when lighting, then by retouching away reflections in post processing. This is something that I've spent entirely too much time working on, so I know how important the "ounce of prevention" philosophy is. In short, when working with a studio light or on-camera flash, you've got to get the light above and/or to the side of the subject enough that the reflection on the glasses disappears. I find with a key light at a 45-degree angle to a portrait subject's face, and a few feet above eye level, I can usually eliminate reflections from all but the most bulbous lenses with simple head tilts and chin movements. Those super-bulbous lenses, however, sometimes make it impossible to eliminate reflections completely, and that's when knowing how to retouch them away in Photoshop comes in amazingly handy. I usually use a combination of luminance- and color-clone stamping, built up over what seems like hours of clicking, and in the end I get a passable result. Check out the recent DPS story on preventing and editing glasses reflections. If you ever photograph people—particularly those with less than 20/20 vision—you'll be glad you did.
