When I use infrared clean on C41 film on a Epson V750 running under Vuescan I get an apparent offset between the dust objects at the patch of photo to which infrared clean is being applied. In the final result I see both the healed spot and the dust object, with an offset between the two.
Thanks for the suggestion. I did contact sup...@hamrick.com and got an initial reply asking for more information. I replied with more information six days ago but did not get a response back, so I thought I would see if anyone here might know what is going on.
Les, I have had the V750 and vuescan for several years, but I haven't used the V750 very much, and I haven't tried infrared clean on the V750 until very recently. However, infrared clean does work on my FS4000US running under vuescan.
Actually, the current version is 9.5.07 - are you sure about that version number? 9.3.x was two years ago, for example. If it is 9.0.58, that's years old and I'd try a newer version. There have been a bunch of changes, including substantial improvements to infrared cleaning, in the past few years.
I'd just make sure you keep the installer around for the version that's currently working for you before upgrading (I always end up appending the release number to the end of the file when I download a new version, and keep a few versions back in case I missed a problem until I try to use a feature with a particular scanner).
I think I know what might have happened with the VueScan version. I recently had the computer repaired, and they installed a new hard disk and moved all of my files and and programs to the new disk. Possibly the recent VueScan version did not get moved, though I am not sure if this was the cause of the VueScan version not being current.
I've found that Vuescan's IR clean doesn't work on any flatbed I've tried it with. It works great with my Canon FS4000US and Nikon LS-2000 though. The difference is that the dedicated film scanners communicate better with Vuescan. Or at least that's my suspicion. I've asked Hamrick a few times to try to work on realigning layers once they're on the computer and he just doesn't see the need. Says I'm the only person who sees any problems so it must be me.
Note, Linux files are case sensitive. VueScan and vuescan are completely different folders or files. So type with care. When you type the above command and press Enter the command prompt will change from:
