    4x5 neg scanner

    Nikon and Polaroid market 4x5 film scanners. Expect to pay between 7500 and 9000 for each. Depending upon your needs, you may be able to use a transparency adaptor with a flatbed, maybe the flatbed you already own. If not Umax Powerlook III is worth investigation. Ditto for the Agfa and Microtek dual units: you get a flatbed and a separate "drawer" into which you can insert transparencies/negatives up to 4x5 or 8x10, depending upon the unit. The cost of this dual units is much less--650-1500 depending upon unit. The Nikon/Polaroid are first class scanners, but again depending upon your use and needs you may find it suitable to pass over 2700+dpi and the cost it entails. Bob Moulton

    Check out the Epson expression 1600. It is a 1600x3200 dpi scanner. You can make an 8000x6400 pixel image from a 4x5. The umax powerlook III is also a good choice. I'm currently using a powerlook III to scan 4x5 slides. The scans are very sharp, but its hard to get a good scan from an underexposed slide. Also, this scanner doesn't do a very good job when it comes to negatives (this is probobly a software problem).

    Check out the Epson scanners before you spend big bucks. There's a model called the Perfection 1200 Photo with a built in tranny adapter that does a good job of negatives. I got talking to a guy that bought one, and he was quite pleased with the results from medium format negs.

    Drum scanners are the next logical step up, they can be had used for $3 - 12K and outperform flat beds for film... however, at a tremendous expense...DRUM MOUNTING! Mounting film to a drum with fluid is a major pain in the ass! Trust me... in my opinion, this is why the Imacon has gained such market share, allmost full benefits of a drum scanner but with dry mounting... and they have have an electostatic field which creates a perfectly flat piece of film. Watch the Dynamic range also, be sure it meets your needs...another reason some wind up with drum scanenrs, once again, the Imacon is almost comparable to a drum.. Good luck...

    Imacon is great, but they drew the line at 4x5. the cheaper, and somewhat affordable scanner does not scan 4x5. drat! also, I understand there is a new version out that will scan 5x7 which would be all too perfect. sell the BMW, cancel the vacation ... heck, spend the kids college fund too!

    Mounting with oil, advised but not always necessary. Mount the emulsion side to the drum and you won't get the Newton rings. I use a Scan Mate Plus from ScanView and only mounted wit h oil ones, ...to see that there was lots of hassles and not so much difference in picture quality. Pe rhaps for scratched small formats at high resolution? I also find operating this 1 PMT scanner (3 passes) time consuming. But the results with this bottom of the line 7 years old 12 bits scanner surpasses what I get from my new Quato XFinity Pro 16 bits flatbed in both sharpness and color clarity! At least it did ! For, now it has to go to revision, since stripes have appeared in the low lights! ...I am just afraid to send it for what it might cost to fix!

    In addition to Paul's response, I also used a ScanView ScanMate 5000 without oil and mounted the emulsion surface to the drum...no newton rings. The only problem I had was that this particular scanner automatically focuses the lens on the surface of whatever is taped to the drum, and since 4x5 film is somewhat thick, I'd have to tweak the focusing parameter to get the lens to focus on the emulsion layer, not the top layer! It did make a difference, even for rollfilm.

    thanks to everyone for your comments. a little more info on my requirements - from now on, when i do a HAER recordation project, in addition to the normal archival prints, i need to scan the 4x5 transparencies and b/w negs for transmittal to the library of congress as part of their effort to get the HABS/HAER collections online. the guys at calumet suggested the agfa t2500 duoscan - a combo flatbed with a lower drawer for transparencies and negs up to 8x12" with no glass plates (no newton rings?). it is about $4500. management will have a hard time even giving me that kind of budget for this, so - is it your collective opinion that this one would do the job, or is there another in that price range that might be better? or, should i accept that i cannot afford the required quality, and continue to pay a local graphics house $35 each for my negative scans?

    to get an example of what kind of quality LOC is looking for (one they scanned themselves), the highest resolution scan of one of the 5x7 b/w negs is a *.tiff file at about 17.5MB - http://memory.loc.gov/cgi- bin/displayPhoto.pl?path=/pnp/habshaer/or/or0200/or0291/photos&topImag es=130784pr.jpg&topLinks=130784pv.jpg,130784pu.tif&title=1.++General+v iew+from+northwest+%3cbr%3eHAER,ORE,26-PORT,14-1&displayProfile=0
