Another issue is control. Some of my exposures with ordinary SG film are
1 minute. With digital negatives they could go down as low as 30 seconds
for gum. True, a gum printer is unlikely to go this route anyway.... but
still this sounds like overkill, unless there's some other improved
quality not yet made clear.
But on 2nd thought, didn't someone on list recently mention trouble with
the digital ballasts?
