Vuescan Questions

[keoj]

I'm a long time user of Vuescan and think the world of it. Okay, I have a Canoscan FS4000 (a dedicated film scanner) that works pretty well but I suspect that a Nikon would blow the doors off of it. The version of Vuescan that I typically use is a 2005 vintage. Today I was scanning some slides and decided to upgrade Vuescan. Typically, I scan slides with a medium IR setting. When I did this with the most recent edition, I saw a ton of dust artifacts on the image (totally unlike the 2005 vintage that I typically use). In addition, the colors are quite different even though I use a ICC profile. Here are my questions:

1) Why would the colors be so different......do I have to recalibrate a new IT8 target with the newer version of Vuescan?
2) Why are there so many dust artifacts with the newer version. Do I need to set the IR cleaning to heavy?

Thanks,

Can you go back to your old version and see if your problems go away? Or did you overwrite it?

I've never seen a change in color from going to one version of Vuescan to another. Very strange, hence my first question. Oh, are you sure the new version is actually pointing to where the ICC profile is? It could be not finding it. And, are you sure it's set to use it? I'd double check all the settings.

Sorry I can't help you with the IR cleaning as I've never used in the five years I've been using Vuescan.

Bob,

Thanks for the comments. I went back to the original vintage and the looked at the colors and yes indeed, they are different. If you don't use IR cleaning, how do you get rid of dust?

I too have seen some really crazy looking dust artifacts when using my version of vuescan and FS4000US. I don't know what exactly it is but some reading suggests that the scan is picking up ultra small pockets of air within the films plastic itself. The only way for me to get rid of it is turn the dust reduction off.

Wish I could help...

One problem that I have dealt with, using VueScan, is if you upgrade in place. Talking to Ed Hamrick, it is usually better to upgrade into an empty directory. Two files (vuescan.ini and vuescan.fs1) can lead to some artifact issues. They did in my case and the problem went away after deleting them. These two files are generated on first execution of VueScan. I am also using the FS4000US. This all assumes that we are talking windows!
