[filmscanners] Re: FW: VueScan file size

["" <focus@adnc.com>]

What file format are you saving to?

The size VueScan gives you is the raw image size. The disk file size can be 
different,
mostly smaller, due to how the information is saved.
I have seen very grainy/noisy scans that when saved as tiff/lzw exhibit what I 
call
"negative compression"--the compressed file is actually larger than an 
uincompressed file!
The other possible culprit is that VueScan gives you the option to save as 
16-bit and/or
with the infrared as a fourth channel.
I'm not sure that either of these would show up in the raw size, but they would 
make the
file size go up
