Re: filmscanners: VueScan 6.6.1 problems - long pass

I ran into similar problems after heavy tweaking of these controls
during my the very first try of VueScan - I got negative' scans which
looked very underexposed.

Unfortunately I wasn't able to find out how to reproduce it that time.

Does Brightness of 1 work just fine for slides in your case? Then it
seems that nominal Brightness for properly exposed film is a function
of film in use. Low speed positive films seems to require 1.4
brightness, but 1 is a good starting point for most negatives I tried.

Don't know about Canoscan capabilities but with LS-30 you may turn off 
Autofocus,
select area to focus with cropping frame at Preview tab and then use 
Device::Focus.
