I've just joined this group...I'm very interested in
alternative processes but have minimal experience,
although I did just get a cyanotype kit so I hope to
get started pretty soon. I have a few questions about
this thread...
1. I've read that a good starting point for getting
negs of the right density is to underexpose your film
by one stop then over develop by 70-100%. Other
sources say overdevelop and overexpose. Anyone have
any suggestions on this?
2. As I only have 35mm and 6x6, I ultimately want to
enlarge my negs, either digitally or via an
interpositive. I've heard that the best way to do this
digitally is using a cheap paper and oiling it. Anyone
have any experience with this? Seems a bit messy to
me...
3. I've also heard that creating an interpositive can
lead to all sorts of problems with density and
contrast. Is there a trick to doing this correctly?
Having done a lot of work with lith printing, I
would've thought that exposing the film for the
"highlights" then developing for "shadow density"
might help...or am I talking crap?
Thanks!
Rob
