[sane-devel] offtopic 35-mm scanner question
the one option in arc photo studio that we definitely need is the auto-adjust something (not lamp, the second one), because the slides are all blurry with that option turned off. auto-remove dust is also good, but only in low mode. if you it turn too high it will just fubar the picture.

I'd have to pretty much agree with breacher even though I'm not familiar with the Epson Perfection 2400 and I'm a newbie with SANE. I've got one flatbed scanner with a transparency adapter built in, and it makes me wonder why they bothered except as a marketing tactic. It's about useless. Negative/slide scanners are expensive, and probably always will be since there's a fairly small market for them which is getting smaller with digital cameras getting better. I have a Minolta film scanner, and I'd say you really want 4800 DPI or better for 35mm. On the other hand, because of the development cycle involved with open source software I've found it's often a good match with the used equipment market. Look over the SANE supported devices and research some of the models that are well-supported that do what you want. Then go to eBay and look around, maybe even set up some searches by model number to email you when one becomes available. There are other used equipment sources as well of course. My biggest disappointment in scanning negatives and slides my family left has been mildew. If these have ever been stored any place even slightly damp, take a look at some of them with a magnifying glass before you invest in a scanner for them. There's about no way to remove it once it gets into the emulsion of the film, and each speck of mildew makes a really big blob in a scan to try to fix in an image editor like Gimp or Photoshop. Mildew is opaque, so whatever is behind it is totally masked. You get what you pay for, but a cheap film scanner is no bargain.

In short, for web posting and small prints I find the 2480+sane to be an exceptionally good combination for the money. Just my 2 centavos, -- Miguel Bazdresch

A used Nikon is a good bet. They have models with batch loaders. Also check out vuescan at www.hamrick.com it has better support for film scanners than sane and is good value for money. Martin

In short, for web posting and small prints I find the 2480+sane to be an exceptionally good combination for the money. I'd like to comment on this also, as I am currently working on making the Canon CanoScan 8400F, work as a negative scanner in Linux. The thing with scanning in negatives is this, first due to the small size of negatives, in order to print of a decent picture requires considerable magnification. This is a lesser problem with medium format negatives. Negatives generally have a dpi resolution of around 3-5000. Hence you'll want nothing less than a 3200x3200 dpi capable scanner for decent output if you plan on printing anything over 4x6. Secondly, it will take you a very long time to scan in a collection with even a dedicated film scanner. Scans at high resolution are huge (100MB+) and slow. The best solution is to take your negatives to a professional and have them scanned and put on CD. It's much faster and possibly more cost effective. Thirdly, most of the windows software with the better quality film scanning scanners has lots of enhancement capabilities built in, that clean up negatives as they are scanned in. While this can be done in Linux after scanning, it is not trivial. So even if you get a professional quality scanner that works in Linux, the quality of the raw scans will likely be less than an equivalent in Windows. If I haven't yet deterred your interest, your best bet is to go with an Epson. Expect to pay around $200 - $400 for one that will be satisfactory for film scanning. There are a number of reviews on the Internet by photographers. Try googling for them. BTW, the CanoScan 8400F and 9950F can both create near original quality scans, unfortunately, neither works in Linux yet, and Canon is not Linux friendly. The Epson 4870 and 4990 are also very excellent. $0.02, Brian JD

i'm afraid the epson perfection 2400 is out of the loop at 2400 dpi. see you can scan films or slides at 1200 dpi without problem, as you zoom you will get squares at the resolution's limit. but at 2400 dpi, that scanner suffers a signal on noise rate loss and the picture is very noisy. it's almost as there was a herse in the way and that you could see it on the picture. however for non-professional applications 600 or 1200 dpi will suffice. if you scan a film at 600 dpi you usually get a picture 700 or 800 pixels wide. also with xsane there is a very harsh setup procedure to get the scanner to work, i've got the bookmark somewhere, drop me an email if you need it i'll send it to you. you gotta extract the ware file off the cd with a cryptic archive command line and set up you the config file using it. it won't work out of the box with xsane.
