    ID-62 is a Phenidone version of ID-20. Ilford markets a developer very similar to ID-62 as Bromophen. The main difference being the addition of a calcium sequestering agent. Since ID-20 uses Metol rather than Phenidone it would produce warmer tones than ID-62.

    The Compact Photo-Lab Index states for ID-20:

    "With Bromide paper, this developer gives good neutral blacks."

    See: http://www.apug.org/forums/article.php?a=217

    I would expect that ID-20 would produce somewhat warmer results if it were further diluted and the amount of Potassium Bromide was increased.

    ID-62 and ID-78 are slight variants of the original formula - ID-20

    ID-62 is the Phenidone variant but due to the addition of Benzotriazole gives cold tones on warm tone papers. It is both a print & general purpose negative developer.

    ID-78 again uses Phenidone which produces slightly finer grain compared to Metol and hence warmer tones, but instead of using Benzatriazole the bromide level is increased instead. It was \designed to be a Warm Tone developer.

    ID-20 gives Neutral tone, ID-62 cold tones and ID-78 warm tones - using warm tone papers.
