I know this may be hard to maintain, but maybe you should add a note
alongside relevant options in the User Guide e.g., "(not available in
so-and-so version)". With displayed options constantly appearing and
disappearing I didn't know if I were supposed to turn on some other
option somewhere else in order to activate it.

But my main question is why is this disabled? It's an essential tool
in order to evaluate certain features. If I read the User Guide
correctly, once a scan is saved as RAW it literally is raw scanner
data with gamma of 1 and various options can be applied to it to see
the differences without having to rescan.

In particular, I wanted to compare the effects of IR cleaning and
Grain Reduction. Of course, I can perform multiple scans but that
defies the purpose because there is no common baseline.

Also, what is the difference between RAW file and "Output / TIFF file
type / 64 bit RGBI"? If I read the User Guide correctly, the only
difference is that TIFF has a gamma of 2.2 (here on Windows) while
RAW, apparently, has a gamma of 1.

If that is the case what's to prevent the user changing the gamma of
"64 bit RGBI" file to 1 and using that as "RAW" TIFF? I may be missing
something here (some loss in quality, perhaps?) but that seems to me
to further defy the whole purpose of disabling "save as RAW"!?

Thanks.

Don.
