The photographic enthusiast likes to lure us into a darkened room in order to display his slides on a silver screen. Aided by the adaptability of the eye and by the borrowed light from the intense projector bulb, he can achieve those relationships in brightness that will make us dutifully admire the wonderful autumn tints he photographed on his latest trip. As soon as we look at a print of these photographs by day, the light seems to go out of them. It is one of the miracles of art that the same does not happen there.
