VueScan and the missed Bits-per-pixel
Ed Hamrick’s VueScan is a great software that supports almost every scanner available, including out-of-production film scanner. Sometimes its interface behave in non documented way as in the case of the Bits-per-pixel option in the Input tab that disappears once the Infrared Clean option is enabled in the Filter tab.
I wasn’t able to figure out the relationship between the two settings until Ed Hamrick himself kindly answered (lightfast, I would say) to my question.
Kudos to him for that, but it would be nice to have this Infrared clean-Bits per pixel issue mentioned in the user guide :)
