We are a Pre-press house starting to work with digital photographers, we are
also new at the whole world of profiling. I see the benifits of profiling
our Iris printer. I also see the benifits of profiling our scanner and
monitors. So, here it goes. In working with digital photographers when
lighting conditions change constantly, the positioning of product changes
and any other variables one can think of change, it seems to me that you
would almost have to build a new profile on every camera shoot. By saying
this I dont meen on every click of the camera, but on every product shoot
where the lighting and the conditions remain the same through out the day.
Especially on some studios where there are alot of windows which bring in
natural lighting into the senario, high noon on a sunny day verses a night
or a dull overcast day. The reason for my frustration comes in when we had
done a test profile on a camera shot one day, which turned out O.K. Then a
week later we had gotten the rest of the job in on disk with about 15 images
using the supposed same lighting set-up, but shot a few days later. The
files came in with out the test chart capture so I applied my profile used
to make our test, (which was made from the color checker test chart captured
with the lighting environment that was supposed to be used in the other 15
captures.) This time however the results were horrific! The neutral
background had gotten more blown out and it put a yellow-green cast into the
hi-light end. I have also spoke with others in the trade whom I respect as
color experts and I seem to get same stories on there results on profiling
digital cameras. I guess what I would like to find out is digital camera
profiling alot of hype or are there alot of people going about this
procedure all wrong. Some where in there I think there's a happy medium.
Thanks for your advice, if any.
