I've produced a test version of VueScan that lets you specify the frame spacing of medium format film when using a Nikon LS-8000 or a SprintScan 120.
I'd appreciate it if people could test this feature. The test version can be downloaded from: http://www.hamrick.com/files/test120.sit (Mac OS 8/9/X) http://www.hamrick.com/files/test120.exe (Windows) Thanks, Ed Hamrick
