What I'm looking for is a source where I can learn the *science* of photography. It doesn't matter if the book doesn't tell me how to use a densiometer, or how to calibrate my development times, but it must tell me things like what density is; how it is controlled (in the negative and the print); why different developers work differently; what the relationship is between things like film speed, contrast, grain; what "tonality" is and why some films processed in certain ways seem to have more shades of grey than others; what exposure and development affects in the print; stuff like that.
