Philippe, looking for a faster way to process thousands of frames … And here again, any
recommendation welcome, well, below the 500€ tag I’d be ready to spend on a new
scanner...
You don't say what sort of frames. It makes a difference. Some stuff about
scanning:
Silver B&W:
This can't have dust and surface defects removed using an IR second scan. Aggressive dust removal saves endless time
spotting. CH and Jan have given their strategies, although both were used on slides.
My limited experience finds that eliminating static charge on the film, then blowing dust off, is effective. I don't
know what's out there these days. I use this thingie from years ago, designed to eliminate static charges on vinyl
records. <http://www.moosemystic.net/Gallery/tech/Misc/StaticEliminate.jpg>
Polaroid Dust Removal, a long ago orphaned bit of software, available free on the web, does a wonderful job of cleaning
up dust, and also seriously whacks image detail. Used in a layer in PS, the mask painted in/out, it can save lots of
spotting time. In this example, I used it only for the sky.

Kodachrome:
KR also has silver in the finished transparency, and was not IR cleanable. However, both VueScan and Silverfast have
worked out ways to do it.
Color Neg, Chromogenic B&W and non KR slides:
I have found IR cleaning to be magic for color negs and non KR slides with my Canon FS4000 film scanner and 5000F
flatbed and Vuescan; a HUGE time and sanity saver.
Jan found IR cleaning with his Nikon scanner to compromise fine detail of slides. I haven't noticed that with the Canon.
I did find that multiple passes could wring a tiny bit more detail out of recent films. A lot of older and faster films
just don't have the detail, anyway.
Scanners:
AG and CH found veiling flare in their Nikon scans. After a lot of trouble and "repairs", CH abandoned them. The Nikons
have shallow DoF, which has caused some people trouble, and a semi coherent light source, which tends to accentuate
scratches, etc. Tina has scanned many, many thousands of slides with a Nikon and auto slide loader.
CH just posted another pic of his camera "scan" set-up and Jan recently described his. I would use a small light table,
rather than the flash CH uses, but otherwise the same set-up.
If you are mostly looking at sticks of negs and batches of slides I think the only good quality consumer scanners still
being made and serviced may be flatbed Epsons? They make under an $200 model with IR and 3.4 Dmax, but that only does 4
slides or two sticks of film at a time, as well as their much more expensive top line models.
Work flow:
I load the scanner, then physically scan all frames to "RAW" files in Vuescan. I don't need to be present while that
goes on. I then "scan" those files to conventional TIFFs, which is very quick. If you ever end up at that point, I can
give a couple of hints about how to make it easier/better.
Hopefully Helpful Moose
