Vuescan solarizing, what's going on?

[Takkun]

FWIW, I'm using a Minolta 5400. Every so often, one of my images will show up like this one. I'm not entirely sure what's up, but scanning again will fix it. Sometimes it doesn't, as is the case with this frame, which I've scanned probably 5 times today..

That is very odd. I was going to ask if you are using digital ice on traditional b+w film, because that can have this kind of an effect, but if that was the case it would be the same for all frames. Have you tried a different version of vuescan, in case it is a bug? I hope it is not a hardware problem...

I think CNNY is right. In Vuescan its called Infrared Cleaning. It doesn't work for traditional black and white films, or Kodachrome. It is only for E-6 and C-41 process films (including C-41 black and white films). This effect is what I get on my Nikon scanner when I have Infrared Cleaning on for a BW neg.

That was the culprit. Every so often I lose track of various settings in VueScan and leave something like that checked…
Scanned that frame again this morning and all was well. Even with IR cleaning on.

Anyone know if its made a difference to those seemingly normal scans that I've accidentally left it on?

I would inspect your other frames at 100%, just in case it left artefacts in some detail areas. I have no idea why it sometimes creates a problem, but other times not.

IR on BW film almost always create artifacts (silver is opaque to IR). Sometimes very evident, sometimes subtle.
So I would inspect, and eventually rescan, all the suspects.
