I have done a little test and looked at VueScan 7.1.2 and Silverfast 5.2 LS4000 new version from Germany. Used scanner in the test LS2000. VueScan can not handle LS4000 and MAC yet. Test object: 3 dimensional test object including Mac Beth , gray scale, black to white objects, silver spoon, map in the background, small round balls, test chart for resolution etc etc. . Controlled studio light situation. Test object for tests of , digital cameras, scanners, films etc. in Photodo magazine ( If you want to know about lens resolution , MTF tests and other things please go to my friend Lars Kjellberg Photodo and member of TIPA . http://www.photodo.com/about/intro.shtml ) Negative film: Fuji 100 ISO. Camera Nikon F5 and micro nikkor . Colors and other results evaluated on MAC OS + LACIE 22" calibrated with Color Vision monitor spyder. Gamma 1.8 Color temp 6500K. Adobe RGB color space in VueScan, Silverfast and Photoshop. VueScan= Excellent in gray scale. no color cast, and very god in red colors. I got the best scanning results to use generic settings with Fuji film and Adobe RGB and gamma 1.4 instead of gamma 2.2. This gives better results between blackness and high lights and contrast in the test object and I have not so much work later on in Photoshop. What can see is: VueScan are not so god in the yellow color (more orange) and green colors are little week and dirty. There are Somme lack of 3 dimension in the picture and some flatness compare to Silverfast. Silverfast have also little more color nuances in details. I have tried to get the same results later on in Photoshop as I can get from Silverfast, but there are still some nuances and 3 dimension missing in the results. Silverfast has a red -pink color cast well known to me and other how have used Silverfast for a long time, it also shown in the gray scale chart in the picture. Red are to intensive but these things are easy to adjust in the scanner software or in Photoshop. All other colors are shown perfectly on the Mac Beth test sine. Conclusion: VueScan are IMO a very good software but can be improved in some details. I can still se that there are some flatness in the pictures produced by VueScan and negative film compared to Silverfast. And a warning. I got serious crashes with VueScan and MacOs. I think its because of that VueScan still use virtual memory ,which on a Mac slows down the computer and gives problem with other programs. I hope Ed Hamrick can get rid of the needs of virtual memory handling in VueScan. VueScan and Silverfast are good working tools, fast scanning speed and excellent results.
