[filmscanners] Re: FW: VueScan file size

["Bob Frost" <bob@frost.name>]

I thought that might be the answer as well, but when I looked at my recent
version of Vuescan, it updates the image size that it displays at the bottom
of the screen whenever I change the output file format, and the raw file
that is saved is the same size as the processed file. I'm sure there is a
simple explanation for this.

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
