RE: filmscanners: Silverfast and LS1000
I use a Scanwit 2720 and Vuescan with Multipass scanning and the alignment appears to be perfect. /fn -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Herm Sent: Monday, July 09, 2001 6:18 AM To: [EMAIL PROTECTED] Subject: Re: filmscanners: Silverfast and LS1000 You can still do multiscanning with Vuescan, but I prefer to digitally align the images using a second program called Picture Window. Registration is not perfect in subsequent Scanwit scans, so multiscaning will slightly blurr the image. Here is the link for Picture Window: http://www.dl-c.com/aboutpw.html The program can also be used to seamless stitch images together to form a panorama. mahimahi [EMAIL PROTECTED] wrote: My cheap Acer 2720s produces realistic colors without much adjustment, but I miss the multiple scanning features found in Silverfast AI.

appears is the key word, I do astrophotography and even the slightest miss alignment will show double stars in the final product. It really depends on how picky you are.

RE: filmscanners: Silverfast and LS1000
I am very picky - I checked several times at 1200% magnification and I saw no vertical or horizontal offsets visible at the pixel level. The reason I said appears is that I assume there is some slack or play in the transport mechanism and perfect can not be achivied. The reason I was skeptical was I tried using multipass scanning on a flatbed (HP5370) and saw the offset effect. Since the offset was repeatable I suggested to ED H (Vuescan) that he include an option to allow the user to input an offset value for subsequent passes. /fn -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Herm Sent: Monday, July 09, 2001 11:34 AM To: [EMAIL PROTECTED] Subject: Re: filmscanners: Silverfast and LS1000 appears is the key word, I do astrophotography and even the slightest miss alignment will show double stars in the final product.

Re: filmscanners: Silverfast and LS1000
Yes thats the reason.. other scanners multiscan before the frame advances, thus they get perfect registration.. The acer must scan the whole image and then average it with another scan.. all things considered the Acer does a good job.. you would be amazed if you tried multiscanning with an old HP S20.. horrible registration.

Re: filmscanners: Silverfast and LS1000
When I've tried multiscanning on my 2720S, I've found it hard to detect any degradation. Misalignment is of the order of one 2700 ppi pixel on mine, or less, so it wouldn't bother most people. I can see it might mess up star locations.

Re: filmscanners: Silverfast and LS1000
Frank, I bet you're right, and this explains the wide divergence of view here on Scanwit multiscanning accuracy which we've discussed at least twice over the last year or so. If using Herm's subtraction method to identify discrepancies, the experiment to do is to compare several different single pass images with a single multipass composite. The smallest differences found would be the nearest to the errors introduced by multiscanning, but this still might exaggerate them, unless one of the single-pass images happened to start in the same place on the frame as the multipass one. Does this make sense?

So, If you actually scan twice the course stepper must be used to position twice which is not as accurate.

I will include an example so you can see it. I inverted the image so you could see the differences.
RE: filmscanners: Silverfast and LS1000
In the documentation which is included on the Silverfast AI CD, A floating window should appear upon selecting negative as a film choice. from there about 6 general brand film types (Agfa/Kodak 1,2,3/Fuji 1,2,) and 3 general choices Monochrome/standard/linear can be selected. Yet another control is shown for exposure. These being post scan color corrections, I do not see why they would be omitted from the Nikon version. - There are no film profiles in Silverfast AI Where have you got that info? Mikael Risedal
RE: filmscanners: Silverfast and LS1000
Hello Mahimahi I read the pdf and there are as you describe a floating window, page 119 in the manual. I have already contacted my friends at Silverfast and ask them about why this features are not included in 5,2 as described.

Re: filmscanners: Silverfast and LS1000
Ian Thanks for the answer. I have not seen any film profiles during the years I have used Silverscan but the pdf file in 5.2 can confuse people. Best regards Mikael Risedal From: Ian Lyons [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: filmscanners: Silverfast and LS1000 Date: Wed, 04 Jul 2001 18:48:46 +0100 When selecting negative mode in silverfast, I do not get the Film type and Exposure window as described in Ian Lyons Tutorial. Am I missing something? My tutorial makes it quite clear that Nikon scanners do NOT use the negative scanning feature as shown in the tutorial. Paragraph 2 :- SilverFast AI 5 for the Polaroid SS4000/120 has a special routine built-in for dealing with the coloured mask found on virtually all negative films. This routine is common to all the other scanner models supported by LaserSoft, except those by Nikon. Although, many of the messages I receive regarding SilverFast and negative scanning relate to the fact that SilverFast does not include film specific profiles, I will demonstrate these profiles are not really necessary. Silverfast maybe have a written software to Polaroid SS 4000 scanner who are including film profiles. Not sure that I understand what this means, but SilverFast does NOT use film profiles! In the documentation which is included on the Silverfast AI CD, A floating window should appear upon selecting negative as a film choice. from there about 6 general brand film types (Agfa/Kodak 1,2,3/Fuji 1,2,) and 3 general choices Monochrome/standard/linear can be selected. Yet another control is shown for exposure. The software for Nikon scanners doesn't support the feature. You don't need the feature, you can ignore this section of the manual, which is written to cover ALL supported scanners. For the LS30/2000 IV/4000 and 8000 there is a Nikon specific addendum on the CD These being post scan color corrections, I do not see why they would be omitted from the Nikon version. Because when LaserSoft tried to make the feature work they failed, miserably. I have already contacted my friends at Silverfast and ask them about why this features are not included in 5,2 as described. The answer will come soon Big :-) Ian Lyons http://www.computer-darkroom.com _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

For the LS30/2000 IV/4000 and 8000 there is a Nikon specific addendum on the CD Ian, your tutorials are excellent!! I did read that the features were not supported by Nikon, But I thought that there would be at least some of the selections available in Negative mode. As for the LS1000, no addendum is included on the CD, nor is the LS1000 included in the list of scanner profile choices in the CMS window. The images(underwater) I scan require some serious tweaking. The deep blue color of the Tropical Pacific ends up bright green. My cheap Acer 2720s produces realistic colors without much adjustment, but I miss the multiple scanning features found in Silverfast AI. If Lasersoft has decided to give up on the LS1000, I hope that a version may soon be available for the Acer. Will try Vuescan this weekend. Hope to get some decent results.

Re: filmscanners: Silverfast and LS1000
Answer 2 regarding film profiles and Silverfast AI Silverfast maybe have a written software to Polaroid SS 4000 scanner who are including film profiles. To Nikon scanner there are no film profiles at all. Ians example are scanned by ss 4000. Mikael Risedal From: Maris V.
