The Color Slide Controversy
Philip C. Beam · College Art Journal · 1943
In the short space available here, the case for color slides can be presented only in outline. Therefore, highly technical considerations must be omitted. This is no great handicap, for as I shall try to point out, the judgment of the case is simple and obvious. We shall keep in mind the saying that one doesn't need to be able to lay an egg to tell a good one from a bad one.
