For instance, fog, underexposure, etc. that cause a significant issue hitting max black AND the resulting contrast needed to get past this just being too much. I'm sure many people will mention split-grade printing - but I just can't seem to get the hang of it with sub-par negs - particularly ones with high base fog as it seems the fog just scales up proportionally. I've gone straight to grade 5 before to try and get around all of this, of course, but sometimes find highlights getting blown to kingdom come. Does this just mean I should do more selective burning in here (starting to sound like I'm heading in the split-grade direction)? There are times I just want to cut blacks and blacks only, which is of course easier to do with a neg scan, but that's not what we're working with here. How many people just leave certain prints as they are and acknowledge that for some it just won't happen?
