Re: filmscanners: Scanning B&W negatives



Ian,

Sorry for the confusion that I caused. In the first post, I  referred my
films brandt and age to better define their features, just in case this
would be important for some suggestions for  scanning them. I was
particularly thinking about their fine grain.

In my second post I just snipped badly. I was so enthusiastic with my
results that I stopped just in time to avoid saying something like "ei
everybody, come and see the wonderful results that I got and how I am living
again so many important moments in my life!"  :-)  .

I should have quoted only that I intended to put "dynamic range" in
automatic, disable all the other tunings in the scanning software, obtain
"pure" raw files for archiving purposes and do all the tuning work in
Photoshop 6. This is my workflow for slides. Most people say that, with 12
bits depth scans , there is no advantage in tuning prior to scan over
working the scan in Photoshop. I read a person that stressed that things are
not absolutely like that, I don't remember already who and where, but my
learning curve is not yet so high to study myself these very intersting but,
for now, difficult subjects.

Perhaeps because, with my Nikon F5 excellent metering and a little with my
experience, it is almost an impossible mission to get a ugly exposed slide,
the workflow above has worked well for me. Not the same with my sometimes
ugly exposed or developed B&W negatives where I must tune the dynamic range
IN the scanning software and sometimes cut large portions of the histogram,
or I will not be able to get acceptable contrast in Photoshop. I am
discovering that perhaeps this also happens in well exposed negatives with
very high or very low contrasts.

I never thought that B&W print was a so complicated subjet and, for now, I
cannot go further than my Epson 1270 with Epson inks. While the prints that
I am obtaining are acceptable, I expect to get in the future much better. So
I am with a problem -- I have no way to be sure that I am tuning well in the
scanning sofware.

Sorry for the very long post.

| Mario,

| Do you mean that for FP4/FP5 its much better to adjust contrast during
