From: Ed Hamrick (hamrick@primenet.com) Subject: VueScan 5.9 Beta Available for Testing View: Complete Thread (8 articles) Original Format Newsgroups: comp.periphs.scanners, rec.photo.digital Date: 2000/01/27 I'm almost ready to release VueScan 5.9, and I'd appreciate it if people could test it out and let me know of any bugs. The main things that need testing are Canon FS2710 scanning, FS2700 scanning (to see if I broke anything), and color negative scanning on a variety of scanners. You can download VueScan 5.9 (for Windows) from: http://www.hamrick.com/vsm.html What's new in version 5.9: All Scanners: * Added "Scan media" option of "B&W Neg". This causes the scanners to not do hardware orange mask removal, but to still apply negative film correction. The default B&W Neg correction is Kodak T-Max. * Improved color processing of negative and slide film. The CCD, light source, and film color characteristics are all used to do color correction. * Added support for raw scan files written by other programs (i.e. uncompressed scan0001.tif files with data starting at offsets greater than 8 bytes into the tiff file) * Fixed a problem when color balance set to "None" * Fixed problem with darkest parts of images when image gamma set to one New scanners: * Added support for Canon FS2710 film scanner * Added support for AGFA DuoScan. You need to change the Scan X/Y size/offset to position the scanned area, otherwise the whole scan bed will be scanned. * Added preliminary support for Minolta Scan Multi and Scan Elite. This isn't debugged yet, but the test code has been left in version 5.9. Scanner driver changes: * Significantly improved color fidelity when using SprintScan 35/35+/LE with negative film * Improved cleaning in dark areas with the Nikon LS-30 and LS-2000 * Cleaning of black & white negatives now works on the Nikon LS-30 and LS-2000 using the infrared channel (the "Scour" setting seems to work best) * Changed exposure times for negatives when using PhotoSmart S20 scanner. This solves a problem when scanning older negatives whose orange mask has faded, or whose orange mask isn't very dark. * Improved speed of lower-resolution scans on Minolta Scan Multi, Scan Speed, Scan Elite * Fixed a problem with auto feed on Nikon scanners * Re-cropping when using filters with Nikon LS-30 and LS-2000 now works properly with memory.tif Regards, Ed Hamrick From: Willem-Jan Markerink (w.j.markerink@a1.nl) Subject: Re: VueScan 5.9 Beta Available for Testing View this article only Newsgroups: comp.periphs.scanners, rec.photo.digital Date: 2000/02/02 In article <949006384.4974.0.nnrp-09.c2dee72d@news.demon.co.uk>, "Ed Hamrick" wrote: >* Cleaning of black & white negatives now works > on the Nikon LS-30 and LS-2000 using the infrared > channel (the "Scour" setting seems to work best) I thought this couldn't work because normal(!) black & white film is silver based, where IR can't get the same unobstructed view as with color neg's (only seeing mechanical artifacts like scratches/dirt)....it gets blocked by metal (silver). This is in fact similar to the fact that ND- and polaroid filters have rather little effect on infrared film....

The IR channel shines through black & white film exactly the same way as red, green, and blue do (all about equally). The darker the film, the more each channel gets blocked - it's a very linear relationship. The trick that VueScan exploits is that the film is almost perfectly grey, but that dust spots aren't.
