I am very interested in this strain: I have always printed my gums in (lo
and behold) sunlight and they have worked out fine, and have heard that
artificial light sources in general produce duller images, but thought I
would buy an Edwards Lightbox in the near future because Montana's sunlight
is pretty indirect in dead winter. So you are saying that fluorescent (sp)
bulbs are duller and lower in contrast than two other artificial light
sources? How about the three artificial in relation to sunlight? It seems
we are talking four sources here: fluorescent, quartz halogen, and metal
halide....vs. sun, of course. So which is best? Or is this anecdotal? In
other words, wouldn't you have to test the same neg 4 times to really get a
good judge of the issue, for perhaps it's the neg that is the problem (or
the gum mixture, etc)? Is there visual proof? Please excuse the snipping
condensation of two messages below...
