And following the same thread from a different angle (as it were!), has
anyone scanned in a print and then
used a PC package like Paint Shop Pro to create different types of
negatives for use in alternative processes??
Im just doing some now to use in gum over cyanotype. Paint Shop Pro
(and Im sure lots of other packages gives a lot of control over contrast
and density, and its the work of a moment to create 3 different density
and contrast negatives, and print them out on a 600dpi laser printer.
The printing paper also looks thin enough to work well as a paper
negative.
Has anyone any experience of this sort of thing?
