All but newbie photographers know that if you flash directly into a glass window, you get reflections that partly obscure the object protected by the glass itself. Microsoft now thinks solving the problem of being a newbie can be done by advanced Fourier transformations, instead of sending the photographer to an introductory class in photography. I guess they see the opportunity to sell a special Windows Glass Edition?
