The reason I was drawn to the idea of tranies is because of their definitive color rendition. What you see is what there is -- if not what there WAS in the original scene. With negative film, so much seems to depend on the printing or scanning ...that's probably the "discovery and general craft" part of what you were saying. Unfortunately, if you don't have the first hints of the "general craft," the "discoveries" mostly amount to disappointments. It's just going to take some work, but that's fine.
