Re: filmscanners: Grain in Color negative Film
Having had a number of conversations with both Kodak and Fuji about
these programs (such as Q-Lab and Fuji Authorized or equivalent), a few
issues should be considered:
1) These programs are optional and cost extra to be in, and are mainly
for E-6 processing (although test strips are available for C-41, I don't
believe any of the manufacturers offer to read them)
2) The test strips for these programs are not done daily, in fact,
usually they are once a week (again, the lab may well be running test
strips several times a day (in fact should be doing so, and reading
them), but those don't go to the manufacturers)
3) The test results are evaluated and reported back usually a week or so
after they are shipped to the manufacturer, meaning the info can be
several weeks old, and hundreds or thousands of roll later, by the time
the lab get the report.
4) The companies admitted to me it takes quite a few considerably off
strips before they will blow the whistle on a lab, and the whistle
consists of removal of the use of their authorized logo. (they usually
return the privilege to use them as soon as the lab is back in "control")
5) These controls test for chemical issues but do nothing in regard to
handling problems like finger prints, scratches, bad mounting, etc.
6) One of the major considerations for an "Authorized Professional Lab"
designation is that they can develop 4 x 5 film, regardless of what it
ends up looking like.
