On the other hand, wood frames are also good. They cost more and scratch easily, but wood offers a certain beauty not found in metal. Just as bright mats are distracting, so too, a very ornate frame can overpower a photo. Choose a simple frame design that enhances without competing with your photograph. You have several choices in what glass to use.
Clear glass preserves the sharpness of the photograph, but glare can be a problem.
Non-glare glass will soften the sharpness of the photograph slightly. Tru-Vue Reflection Control glass is my favorite, because it causes very minimal softening of the image. For the ultimate glass, UV absorbing glass is now available. However, it's very expensive. Besides, recent research indicates UV rays are not the only villains.
