I recently saw a print of a Edward Weston original printed by Kim Weston. The subject was Charis in the sand. Upon inspecting the print it appears the subject is printed at a different contrast (higher with nice low mid boost) then the sand (low and flat) ,and she is surrounded by a fine black line of differention, a great technique to highlight a subject.
I know little of Edward Westons technqiue but it looked liked something that a modern photographer might do in photoshop. I am trying to comprehend the possible analog techniques that could be used to arrive at such a print. Certainly a composite negative could be made from a series of duplicate negatives printed at different contrasts. Perhaps there is a technique of masking using two masks of slightly different sizes, one for the black line and subject, the other for the subject.
Any thoughts or ideas?
