What, if anything, have Imacon compromised in order to produce the much more affordable 343?
I've been looking for the perfect 'budget' (LOL) scanner for my Mamiya 7 and Xpan rolls for a while.
A quick trip to the Imacon website (
http://www.imacon.dk ) gives you all the specs. Basically, the 343 lacks the speed and resolution of the higher-end units. Also, you are limited to 35mm & 120 mm film sizes on the 343. The 646 and 848 can do 35mm to 12x17mm. They are all firewire single-pass scanners. (848 has SCSI ports also)
848: 80dpi to 8000dpi (optical), 100mb per minute/16 bit per color, 20-3800% magnification, 4.8 Dmax (quoted)
646: 80 dpi to 6300dpi (optical), 40mb per minute/16 bit per color, 20-3000% magnification, 4.6 Dmax (quoted)
343: 80 dpi to 3200dpi (optical), 20mb per minute/16 bits per color, 20-1500% magnification, 4.2 Dmax (quoted)
Check out this review of the Minolta Scan Multi Pro film scanner by Ken Rockwell. It's a $3,000 scanner and he prefers it to the Imacon scanners. Bascially because the Imacons do not come with dust & scratch removal features, but they do sell a program called FLEXTOUCH which works like ICE.
http://www.kenrockwell.com/minolta/mp.htmOne very cool Imacon feature is the ability to work and save scans in their proprietary 3F format. This is basically a tagged tiff format. You make a RAW scan of the original, then you save it as a 3F original. Now (in Photoshop) you can make adjustments to the raw scan, say maybe drop it to 8 bit, do sharpening, adjust the image size, and when you're done, you do a File>SAVE AS, keeping it a type 3F. As a result, the original raw scan is kept pristine for future "repurposes", and the file sort of carries your adjustments on top of the original scan. So in the future, you can get back to the pristine state as easily as going back in a file's History in Photoshop, and you can also instantly and easily go right back to other 3f "save as"s you created from this file.
Imagine that you have a high res scan that you need to get ready for a color newspaper ad. If it's in 3f, you would open the high-res raw original, make your adjustments and save as in 3f again. Then in a month or so, if you need another copy for another color newpaper ad, you can open the original 3f, and you can go right to the last color ad version you created, without having to go through all the work.
I don't know if I'm explaining or confusing, but I think you can see that there are benefits to the Imacon beyond scan quality.
If anyone else has experience with both the Minolta AND the Imacon, I'd sure love to get your 2 cents worth.
