Oh I don't know - I've met more than one photographer who has covertly duped
35mm to 5x4 to meet a client requirement for sheet film ;)
Seems to me this is all a matter of intention. If later manipulation is
intended, high bit TIFF output should be specified.
If it's going more or less straight to press or other output, people will often
prefer JPEG. Apart from much shorter wiring time of JPEG, TIFF format is
mutable enough to cause occasional 'aargh I can't read this!' problems which
are not wanted where deadlines are involved (BTDT).
I have to agree with Ed that JPEG at high quality settings is close to TIFF,
close enough that you'd never see any difference in printed output. The smaller
files are much more manageable, so favoured for transmission.
I can see it both ways, and it seems the answer is to know what you want and
specify it clearly. And for the lab to ask, rather than assume. Both preferably
before they do the job:)
