Fred advocated first testing to determine film speed and development time, as per his book and video. It is a simple, straightforward system. He felt the most negatives benefit from increased exposure than strictly called for by placing the lowest shadow area with detail on zone III, with zone I .1 above FB+F. He felt that by placing the brightest highlight with detail on zone VIII, that one would guarantee the most exposure (without shouldering tri-x), at least with the types of scenes that Fred preferred. (He didn't like photographing back lit scenes, for example.) Suppose that the brightest area that one wanted detail in fell on zone VIII (given a zone III shadow placement.) Instead of giving an expansion development, Fred advocated placing that highlight on zone VIII, developing normally, and worrying about contrast at the printing state. Fred was concerned that many of his students were getting overly involved in development expansions and contractions, when they should spend more time actually taking photographs. (I had some strange results when I ran my first film test. Fred said, "Stop obsessing. You're close enough. Go take pictures!") His system worked quite well, especially with roll film. Obviously, there are extreme lighting conditions where it won't give an optimal result. I shoot large format. I don't bother with + or - 1 development, as that's well within the range of my paper. If the scene requires greater expansion or contraction, I'm happy to do so, but this is rarely the case. -Peter
