RE: filmscanners: Large collection - full frame projection via DLP & PowerPoint

Hi, Marvin--

I think that Ira's idea of the digital camera (instead of a
one-size-fits-all film-scanner, which isn't really available) is a very good
idea. I'd thought of it myself, but 18-months ago it wasn't a workable
option. Possibly now it is.

Vis-a-vis a "copy-board," you only need to be sure all your (reflector-type)
lights are at a perfect 45-degree angle to the copy to avoid bad
reflections. Vis-a-vis shooting negs and trannies, that the light is greatly
disipated with no spill (a good milk-glass or fine-sanded glass filter over
your light source, given a bit of distance and some black velvet, will do

Seems to me that you could also photograph slides rear-projected on a
fine-cheesecloth "scrim" using a remote slide-changer. Old movies used to be
done that way (now they project from projector to recorder, which is a whole
'nother matter).

It sounds like a very interesting (and fun) project. I'm grateful that in my
own project, I didn't have the med-format negs and trans to cope with!
Saving to 800x600ppi also gives you a better "target," although it will
raise questions of its own. By all means, look at Larry Berman's pages (op
cit). If you don't have a storage problem, JPEG at nearly the max--it saves
on decision time! :-)

Like the man said, "Wish I had that setup when I started!" :-)

Good luck & Best regards--LRA

Subject: filmscanners: Large collection - full frame projection via DLP &

My current project is to take a large collection of multi-format negatives
and transparencies (35mm to 4x5), b&w color prints (billfold to 8x10) to
scan them into JPEG for insertion into PowerPoint 2000 slides for full
frame projection via DLP (Digital Light Processing) at 600x800 pixels.

I have started with the flat art and have found the process slower than I
would like for it to be.

I love the concept of looking through a 35mm single lens reflex finder,
composing the photo, exposing the photo and then quickly moving to the next
subject.  Is there any scanning process that accommodates this approach?

Any one have ideas as to ways to approach this project?  Has any one
handled a large project of this type?  If so, how did you approach the
