I have a gorgeous negative, one that I really feel is worth spending a bunch of paper on, but it is proving very difficult to print. I have flashed the paper and tried burning in the sky with a hole-in-a-card but still very little of what is in the negative shows up in the print. I am split grading the main exposure (18 seconds at grade 00 and 21 seconds at grade 5). I am going to try cutting out a cardboard mask that matches the treeline but I am wondering how to get around the problem of irregular tree shapes with fine detail as well as avoiding the creation of an obvious line from the mask? It will probably need at least twice the overall exposure so I am thinking that I will do half with the mask directly on the print and half moving it around to avoid the obvious band. Any other suggestions?
