> developer is as important, if not more so, than the film in getting an extended range(posted 8320 days ago)That's a very important point. Some developers which produce a bit of a shoulder in normal usage can just block up (curve goes flat) at a rather low density when they're used for a short time or high dilution for a strong contraction. While the result is a much lower density on the high end, it's a no-contrast detailless density.
