I may do that, but the LS-30 should be able to do the job. That's
what we bought it for. I talked my boss into it, so now I need to
produce.

I don't insist on slide film. I have been working off the advice
of local photographers and labs here in the S.F. bay area.
The blue bulbs were an easy fix when used with daylight film. I
originally started with tungsten lights and film. But had some

Thank you, that's what I meant.

And negatives are way easier to shoot with good results.
Yeah, but isn't that because most negative films have tons of
latitude? One could be off a stop or three and still get a
useable image?
Postive film really wants the exposure to be right on, but is far

Mike,
I am glad you have had so much success. But you apparently have
far more experience and equipment than I do. All your great luck
with "C prints" helps me none.
What I have is what I have. And with what I have I should be
able to get the LS-30 to produce a scan t

I had already written it down and plan to buy some on my next trip
to the "toy" store. I am always willing to try a different film and
see what I come up with. I have plenty of tungsten photo fl

I'm not sure if anyone with more knowledge of film chemistry confirmed this
suspicion of mine - that the graininess of print film of a given rated speed

OK, here's a suggestion which was made to me when I had concerns about
focus. Score a very fine line on

It should be the opposite.
