I think it is scientific, with same JPEG compression level the more detail 
the larger file size. I knew this some time ago and was looking at the file 
size for quick judgement of the OM lens tests I did with E-3. But I just 
post test images for the visible difference, it is easier to judge how good 
or bad the lenses are.
