RE: filmscanners: RE: filmscanners: Gizmo to make flatbed scan large format film?
If your flatbed does not have a tranny hood try the SlideScan www.slidescan.co.uk which fits most flatbeds (about 4 in 5). It uses mirrors and a clever adjustable screw which changes the angle of the light hitting the mirrors from your flatbed. Image quality is strictly dependant on your flatbed. It could be ok for your purposes for web use or for small prints (5 x 5) from a 600 dpi flatbed with 6x6cm film (output at 300 ppi). Double the print size (ie 10x10) using a 1200 dpi scanner or output at 150ppi from a 600dpi scanner. MegaPixels offer a 14 day no quibble returns policy - but only sold in UK (no US distributor yet).

Re: filmscanners: Gizmo to make flatbed scan large format film?
Wiping the tears from my face, after a really hard laugh... ;-) More seriously, this idea is not only not funny, but indeed is produced by many scanner manufacturers. AT one time it was an option that one could by separately (often at a way too high cost). The main problems with using a flatbed scanner for scanning film, in general, is contact with the glass surface causing Newton rings, and that most lower end flatbed scanners have compressed dynamic range. 35mm film scanning on flatbeds can also suffer from the scanner having too low a resolution. However, medium and large format films can create a reasonable file size even at 600-1200 dpi. Better quality flatbeds might have a special drawer which might not use glass, and a separate optical path and lens for film, and, of course, better sensors with wider dynamic range. The problem with scanning films on flatbeds is the need for a light source which goes through the film from above. The best method is, of course, buying a scanner which has a transparency adapter, which plugs into the scanner, and usually lets the software know a film is being scanned, and in some cases, but not always, shuts off the reflective lightsource. You can buy relatively inexpensive scanners which have these transparency light sources as add ons or incorporated into the hood (under $300 US). These have software profiles for negatives to remove the dye mask (orange background), which most flatbed scanner software usually doesn't include. Not all newer scanners with this feature can scan a full size large format film. Newer scanners make use of the sweet spot of the scanner to scan a medium format film (up to perhaps 3 square). For some reason, older units seemed to be designed to scan up to 8 x 10 transparencies/negatives. You might wish to look on something like e-Bay for either an older scanner with the adapter, or an adapter for your scanner, if one was made. I have heard of some people successfully scanning large format transparencies by placing them on the flatbed with the hood open, using a relatively bright, but diffused lightsource that they track along with the scan head as it moves. It would seem to me tricky but possible. Apparently, you need a bright enough lightsource to overpower the reflective light, if that can't be shut off. If your scanner has a transparency top interface plug, you might wish to look around on the web and see if anyone had mapped it, as there might be a simple way to put the scanner into transparency lighting mode. I have seen this for some UMAX scanners, and I do doubt that IBM made your scanners, so you might need to find out who OEM'd it for them.

Thank you everyone! Herb For my own medium format (6x7) and 4x5 slides and negatives, I use an Epson 1640SU Photo. The Photo means it comes with the transparency adapter. There has been a lot of discussion on this list about the quality of this scanner, but I find that, for the price, it does an excellent job for me. Your mileage may vary.

The only sort of thing I'm aware of which does this is a purpose built light-lid. If the scanner model doesn't have one as an option, you can't do it. I've tried various kludges, but nothing works well. Essentially you need a scanner which is built for the job. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com
