Hi Paul, I use a tungsten source (dichroic) for my medium and
small format stuff, and a cold light for my large format work
(and sometimes for medium format also, it depends on my mood).
What I have found with my coldlight (mine is an Aristo) is that
I had to put a 40Y filter above the diffuser to make it
compatable with VC papers. The spectrum is a little too blue and
the contrast was just a bit high as a consequence. Adding the
yellow filter made it all nice again. Normally, I am using RC
papers for proofing and initial prints so that I can get an idea
of what sort of exposure manipulations I am going to have to
make, then I switch over to graded paper for my final prints.
Getting FB prints to dry flat is pretty well impossible, but the
best method I have found is to dry them face down on either a
fiberglass screen, or a well washed bath towel. Both methods
leave the print reasonably flat, and a few minutes in a dry
mount press will usually leave them flat. I dry mount the FB
prints, and I will mount a garbage FB print on the back of the
board. This ensures that the board stays flat by imparting an
equal but opposite curl to it.
