Re: Alternatives to vuescan
From: Alan Chan [EMAIL PROTECTED] I am afraid there is a bad news. Vuescan is known to have streaks when using Minolta scanners. My Minolte Elite has the same issue as well, particular with the blue channel. What I have found is that the mirror inside the scanner has some spots which the software should take care of, but Vuescan doesn't. The streaks can be fixed with Single Row Marquee Tool in PS but time consuming. Another software I am aware is SilverFast, but I think they support Scan Dual III IV only. No streaks with vuescan and my Scan Dual II. Nor any that I have heard about from others either. What is the source of this information? Rob. -- No virus found in this outgoing message.

Re: Alternatives to vuescan
SilverFast does a good job too, but I prefer Vuescan's algorithms. And Vuescan is cheaper, can handle a ton of different scanners if you decide to move to a different scanner at some point. I use it to drive both a Minolta SDII and an Epson 2450. I had a look at Silverfast but didn't like the one scanner option although ultimately I suppose it could be more accurate, I'd also like to add an old Umax Astra 1220S flatbed to the SCSI chain for the odd print scan. 48bit TIFF (with LZW compression if you want to save space) and the maximum optical resolution of the scanner are good (I am not sure of the optical resolution of the Scan Dual, I have a Scan Dual II and I know that's 2820ppi). I'm thinking of going without compression then writing everything to DVD+R or CDR at some point, although I have yet to select the blank media, Fuji, Traxdata? I believe the maximum resolution is 2438 dpi which results in max. 3504 x 2336 about 8.18 million pixel, not the best but it's free :) A couple of tips: - If you batch up your negs/slides into groups with similar characteristics, you can then batch scan with one set of settings more efficiently (up to strips of 6 negs or 4 slides with that scanner, I believe). Yes I was working on saving profiles for particular film types and loading them each time I switched film emulsion, I've yet to figure out if vuescan will batch scan unattended (without me manually feeding that is) The advantage to scanning and saving RAW files in Vuescan is that it will do much like a RAW format in a camera ... dump the scanner's raw data out to a file ... which can then be reprocessed many times with different rendering settings to get a better scan. Much better than re-scanning the originals many times, and a lot quicker. Of course, it costs more time and space to save RAW files. Whether its worth it to you only you can decide. (A lot of my negatives are archived digitally as a Vuescan RAW file, a 48bit TIFF-LZW file, and an index page per roll of film.) I really will have to dabble with RAW at some point, I could basically produce TIFF and RAW at one go with each negative plus the index page I suppose, why are the RAW files given a TIFF file extension is RAW not a format in it's own right? Scanning is a slow and tedious process, but I like having archive copies of my negatives and prints that I can replicate losslessly and manage electronically. It will pass the time at lunch where I work :) but needless to say it will be a long job, I just wanted some informed opinion from experienced users such as yourself before starting only to find I'd gone down the wrong road :) Many thanks for the info and tips. Best regards, John
Re: Alternatives to vuescan
Thanks Alan I've not noticed any streaks yet but I've only scanned around 20 negs, one particularly old negative did produce what I presumed was a scratch. If there are spots on the mirror I would assume the streaks would be horizontal across the scan? If this is the case then I think it was a scratch caused through bad darkroomn practice on my behalf. You're correct in saying the original Scan Dual does not seem to be supported in Silverfast which is a shame it would be nice to try an alternative.

Re: Alternatives to vuescan
I suspect something else could be the problem. When I first got the Scan Dual II, I ran the MInolta software. I wasn't satisfied with it, it both tended to crash frequently and my scans weren't particularly sharp. I'm finding the results with Vuescan much better than the supplied software with much better facilities for fine adjustment, colour rendering appears to be significantly better also. John

Vuescan's RAW has minimal metadata (he generates the processing parameters by analyzing the scan data on the fly) and the sensor data is basically just a row x column matrix of RGB pixel data with linear gamma, that's typically what scanners produce as straight output. Processing RAW output from BW negative scans means doing the inversion required and then adding the gamma curve conversion to what our eyes like to see... relatively simple to do. Processing RAW output from color positives is somewhat trickier as color positives have a higher gamma than negatives to begin with. Processing color negatives to RGB positives ... well, you have to invert it, remove the crossover mask per the particular film's profile, then gamma correct it. I'll let Vuescan do that for me. ;-) Godfrey __ Do you Yahoo!? Yahoo! Mail - Helps protect you from nasty viruses. http://promotions.yahoo.com/new_mail

I have found the Minolta software produces better results for slides than Vuescan, while Vuescan does a lot better for negatives (colour or BW).

However, for my scanner (oldest Elite), if the slides look a little dark, the scans will be too dark and useless. That's one reason I am not too keen on shooting slides. Perhaps the latest scanners (Nikon 5000 Minolta 5400) will do better?

Hmm. Interesting. I suspect something else could be the problem. When I first got the Scan Dual II, I ran the MInolta software. I wasn't satisfied with it, it both tended to crash frequently and my scans weren't particularly sharp. That's what motivated me to try Vuescan ... Vuescan's focusing algorithm is far superior to Minolta's, at least for the Scan Dual II: my scan's became razor sharp, and Vuescan never crashed on me. If the streak is a very thin, 1pixel line, it's possible that the Minolta software simply doesn't resolve it. Of course, the Minolta Elite is a different scanner from the Scan Dual and Scan Dual II, with different hardware in it. I don't believe there's a mirror in the SD models at all (could be wrong). I have had excellent results with the SDII and Vuescan, it has never let me down. I don't do much scanning anymore, but I keep up to date with Vuescan releases and it's all I use.
