[filmscanners] Vuescan 7.5.b10
Just loaded the new Vuescan on my Mac with OS8.6 and 256 mg of ram. When the scan begins I get a message saying that it is unable to allocate enough memory and to increase my virtual memory. I never needed virtual memory before, which I keep off. Is there a way around this? 7.4.2 runs fine without it.

[filmscanners] Vuescan 7.5b3
I'm having a problem with the most recent Vuescan: the final scan doesn't match the preview, neither in the Vuescan window, nor in Photoshop. When I switch back to 7.4.2 it works fine. I may be doing something wrong, but I can't find it. Any ideas?

Re: filmscanners: Vuescan and Overexposed Negs
Arthur, thank you for the excellent advice, but I'm not quite sure how to make different exposures using Vuescan. Adjusting the Gamma didn't seem to affect the blown out white; changing the white point to 0 didn't seem to make a difference either. Am I missing something? How do I bring down the exposure so that I can bring out the detail in the whites? STEPHENJENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED] I assume this image is on negative film, because if it is on slide film, the detail is gone forever if it isn't visible on the film. If it is on neg, your detail is probably there, but the overexposure of the whites makes for a very dense area on the neg. You need to expose for those areas while scanning, which will probably cause the middle and dark areas to get too dark. You might wish to make two scans at different exposures and then using a photo manipulation program, like PS, layer them. One of the easiest ways to fix this is to place the blown out dress image (which has good exposure otherwise) on top, and the one with the good dress detail underneath. Then, set your erase tool to 15-25% using a soft edged brush and slowly remove the upper layer in the area of the dress allowing the detail version to come through. This way you can control each area of the dress, and bring up the detail just to the point it looks best to you. If the dress from the lower level doesn't look oddly exposed in itself, you can use the erase tool at nearly 100%, and just erase the blown version that is on top, for a quicker result. Art

I have a neg of a bride in window light and her gown is burned out. Any suggestions for bringing in detail in the scan process? STEPHENJENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED]
Re: filmscanners: VueScan 7.1.2 Available
Is there no longer a 'Clean' feature for the Sprintscan4000? I see only 'Grain Reduction.' STEPHENJENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED] Earlier versions basically limited the size of the largest dust spot based on wither the cleaning was set to light, medium or heavy. The current version tries to remove dust spots regardless of how large they are, so there was no need to specify a light, medium or heavy option. Regards, Ed Hamrick
Re: filmscanners: Is my Polaroid SprintScan 4000 faulty?
I have a similar problem with my Sprintscan when I scan BW negs. I sometimes get a bleed from dark area into light. I'd be interested in what others have to say.

Robert, I wonder if you would mind taking a look at the images I've posted on this web page... http://users.bigpond.com/robert.groom/ss4000/ and then letting me know whether your conclusion is the same as mine. A rather obvious question but have you tried scanning the same slides in different orientations? I thought I had similar problems with some colour fringing with my Minolta Elite but the direction with the fringing remained the same whatever the orientation of the slide. I tried back to front, upside down and even sideways (which meant not all the slide was scannable) and the offending parts of the image always looked identical. As far as I can see, the effects of optical abberations in the scanners lens, CCD bleeding etc would change with the orientation of the media. Looking at the slide on a lightbox with a x20 hand lens I could detect the fringing on the original which I hadn't noticed until I'd scanned it. If this caught me out with a 2820 dpi scanner, I guess the 4000dpi of the Sprintscan would make it even more noticable. Al Bond
Re: filmscanners: Re Insight or Photoshop?
This would depend upon your level of expertise with Photoshop. If you are a novice, stick with Insight; it's quick and easy and gives reasonably good results. If you are good at Photoshop, use Insight to output a raw 16bit file with profile embedded, and do the adjustments in Photoshop. Or you can try Vuescan.

I, m new to this site so if this has been covered already, I apologized. My scanner is the Polaroid Sprintscan 4000 with Insight. I use Photoshop 5.0. I would like to produce high quality 11x17 inch prints on my Epson 1200 printer. My question is...should I use the Insight software for my adjustments or just do a basic scan and do most of the adjustments in Photoshop? Also should I sharpen the image at all before the final scan or do it in Photoshop. Thank-you.S. Sisk
Re: filmscanners: VueScan 6.7.3 Available
Ed, I have a Umax Astra 2000U. I opened up Vuescan 6.7.3 but it doesn't show the scanner in the Scan From option. Is there more that I need to do?

It can be downloaded from: http://www.hamrick.com/vsm.html What's new in version 6.7.3 * Added support for USB scanners on Mac OS (HP S20 film scanner only supported on Windows) * Improved robustness of USB scanners on Windows Some other information from the release notes for users of Mac OS and USB scanners: If your scanner has a button on the front and if a program starts up when you press this button while running VueScan, you need to disable this behavior to get VueScan to work properly. Unfortunately, it appears that this behavior can't be disabled on some scanners, especially Agfa USB scanners. To disable button polling on Epson scanners, use "Epson Scanner Monitor Setup" in the Apple menu (uncheck "Enable monitoring"). VueScan supports the same USB scanners on Mac OS as Windows (except for the HP S20). You need to first install the software that came with the scanner and verify that the scanner works (you only need to do this when you first install the scanner). Regards, Ed Hamrick
Re: filmscanners: VueScan 6.7.3 Available
Oh well, you seem to be getting closer all the time. I'm so pleased with the way Vuescan performs on my Polaroid Sprintscan that you'll get no complaints from me. In fact, I'd consider getting a different inexpensive flat bed scanner just to be able to use Vuescan for it. Is there one that you recommend?

They don't use the same type of commands as the scsi Umax scanners, and the command format they use isn't documented (and can't easily be reverse engineered). VueScan 6.7.3 adds Mac OS support for those USB scanners that were previously supported in the Windows version of VueScan. Regards, Ed Hamrick
Re: filmscanners: This Gamma Thing...?
Tony, for us users of Vuescan on a Mac scanning for output to an Epson Printer, would 1.8 be good gamma starting point? Vuescan defaults to 2.2, I'm guessing because most users are on Windows. STEPHENJENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED] To be more practical, Macs use a system gamma of 1.8 and are historically the de facto standard in imaging. Therefore 1.8 is a 'good value' if you are working with designers who will be using Macs. However Windows machines are much more numerous. If you are aiming at cross-platform medium such as the WWW, 2.2 is probably a safer assumption. There's some stuff on my site about all this, and it's well worth reading Prof Charles Poynton's FAQ about Gamma (link at my site). But don't be too taken in by it - he is talking only about video systems and optimal presentation. We tend to have to worry about data precision as well, through iterations of editing operations.

filmscanners: Avoiding Posterization
I've been scanning bw negs in Vuescan, basically using the default settings, and every so often I get a little posterization in the dark areas of negs with a really extreme range of lights and darks. What is the best way to avoid this? Increase image brightness (eg., from 1 to 1.2)? Raise the black point (BTW, how does one do this? Change it from 0 to -.01 for example)? Adjust the media settings? Anyone have a preferred method? Perhaps it's not a problem; is it ok to have some 0 values in an image? I'm experimenting, but an experienced opinion would be very helpful.

filmscanners: Avoiding Posterization with Vuescan
I recently had a computer crash and had to re-install just about everything. I also recalibrated my monitor using Photocal and the mc7 sensor. After I did this I opened some bw files in Photoshop and discovered posterization in the very dark areas that I hadn't noticed before. I use Vuescan to scan bw negs on my Sprintscan 4000, and I suspect I need to make some adjustments. What is the best way to begin? The scans that show posterization have extreme ranges of light to dark. Is posterization unavoidable on these types of images? STEPHENJENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED]

Re: filmscanners: Binuscan for SS4000
Ed, I'm not sure what you mean by "it's the same as 2.2/gamma." When I scan 16 Bit Grayscale using Vuescan and my Sprintscan4000, the first thing I do when I open the file in Photoshop is Adjust/Levels/middle slider to 2.2. I then apply a curve based on 30/20; 50/50; 70/80 to boost the contrast. Works great every time. Is there a way to make this adjustment in Vuescan? I'm sure there is, but I'm just not sure how. Also, is it better to make this adjustment at the scanning stage in Vuescan, or in the post scan stage in Photoshop? Stephen STEPHEN JENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED] I'm looking for something that will accept 48-bit raw scans I have made with the SS4000 and do a reasonable job of compressing the tonal range without muddying the shadows or blowing out the highlights, and generate 24-bit files my client can look at and decide which images are really worth looking at more closely. VueScan will do this nicely. Just experiment with the "Color|Image contrast" option (it's the same as 2.2/gamma). Regards, Ed Hamrick
Re: filmscanners: Profiling, Ilford XP2 and Vuescan.
I believe that XP2 film can be processed C-41 like color neg and is often printed on color paper. The green or brown or blue print color is due to the processor operator's sense of neutral color balance. If you scan them as grey scale you should get a neutral bw image. If you scan as rgb you'll get different tones. The grain is most likely due to your scanner scanning more sharply than your lab prints. Also, some labs print their bw minilab stuff digitally, so your scanner may be sharper than theirs. STEPHENJENNINGS P h o t o g r a p h e r Cambridge, MA [EMAIL PROTECTED] I have this question: Should a white balanced vuescan scan with film setting generic of Ilford XP2 (a monochromatic film) look black and white? I ask this because the first time I used this film I got sepia toned prints back from the lab. The other times they were greenish or (dark)brown/white prints. At the time I liked this very much. However: when I used vuescan to scan this using settings black/white, film: Ilford XP2 I got black and white pictures that showed a lot of grain. As soon as I used generic setting they became dark brown and white. I thought this was because of the color of the film (a bit like purple!?). However, when I recalibrated my screen using the 6 squares of the (I believe www.photoscientia.co.uk) photoscientia website instead of the 3 squares of the adobe gamma or basic wiziwyg profiling tool, I got better colors in general, even though the squares of the latter tool seem off! And to top that, the scan of the ilfor xp2 film is now black and white in the generic film type setting (and less grainy)! So, I wonder whether I got my monitor profiled better now, or that I should let somebody else do it.
