I think you mean "infer" rather than "imply"!

No, you cannot imply that as there is no statement in any of the
manuals that TIFF is processed, only that it is not compressed. It remains
to be seen if there is any processing taking place in the E-500 TIFF files,
and that means returning to where I left off last year and now evaluating
TIFF images.
I think the best way to proceed with this is to use the test card
provided in the back of "Filter Practice" by Clauss and Meusel and then
compare the digital TIFF and ORF results with their film results. I did
this last year with the JPEG images and that's what raised the issue of
using Wratten filters with digital B&W.
