Hmmm - this whole thread seems an odd one to me, and I'll admit
to trusting Wheatfield's many previous (anyone notice he's staying
out of this go-round?) expoundings on pushing C-41.
The main "bugaboo" I see in what I have read on this experiment
is that there was no "control" of the same series of exposures
w/ normal processing. That the 1/125th "correct" exposure would
be ultra-dense seems a given if the film was "pushed". Likewise,
with the "push" it would seem natural that the least exposure
would be least developed and at least seem better than the others
which were obviously overexposed for such development. Best would
be to compare well done prints, of course - though digital after
processing appears to be an acceptable part of the experiment's
end result goals - so it's a "whatever works" kind of thing ??
I would want to compare shadow densities & detail between a standard
processed negative and the experimental 2-stop push. I would also
feel better with the results if ambient metering and a more
controlled and identical lighting was used for both these rolls,
the test and the control, together.
that said - I am actually ambivalent as to the whole thing and
will continue to shoot C-41 1/3rd stop over as a rule and, when
seems appropriate to get a bit more shutter speed, 2/3rds under
with standard processing and take some advantage of latitude.
