I am trying to figure out how to fully read a film characteristics curve chart. I understand how to read the toe, the shoulder, and also the part in between them. I understand a long toe with not have as much contrast, and or detail, in the blacks and shadows of a print as a short or straight toe will. Also the same with a shoulder that is long. It will just blow out anything white above it in the print, compared to a short/straight shoulder. Also the section between the toe and shoulder, steeper=more contrast, less steep=less contrast. correct me if im wrong with whats above. The thing that I am not understanding is why a film that has a long toe and a straight shoulder (txp) is harder to print then a negative with a long toe and long shoulder. I think it would be easer to print a negative with a long toe and a straight shoulder. Is the reason because they are trying to preserve detail in the shadows? Thank you in advance. And if im completely wrong, dont be soft.
