Re: Digital step tablets

Don,

thanks for the info. It happens that it is exactly the same procedure as I
thought except for the use of the densitometer. This adjustment or curve one
obtains this way gives us a linear translation of our image on screen to our
image on paper and it's just fine.

What I tried to add is that I'm beginning to think this is only a starting
point and an excellent one at that for sure. But an image on screen is so
drastically different then one on paper, I have serious doubt that a simple
linear translation would bring out the best possible qualities of the image
on paper. Further then that, I would add that each individual image will
need it's own set of tranformation to make it our most satisfying print. I'm
sure you understand, there are a gazillion little details that can make a
significant difference, the paper for example, how many time have you eard
folks here say I use this or that paper because I presume they like what
they see, the textures, the nuances and all those little things that make
the difference. I also underestand one could be quite satisfied with a
single curve for all of his/her prints made using the same process, I just
have serious doubt I will. I don't recall who said this but I remember
someone saying that some image are definitely "this" process while others
are "that" process and I presume some can be done using a few different
process. This kinds of tell me that if a process can better render the
qualities we seek in a print and even a different paper can do the same it
is more then possible that an "exploration" of the possible adjustment one
can apply to a single image can bring its best potential. All this doesn't
even take into consideration all the possible twiking one can realise during
exposure, development and toning of a print when it applies of course.

Yves,

If you haven't already done so, you may wish to read the online article
written by Huntington Witherill, "Calibrating Digital Output For Black and
White Printing". He describes his technique of creating digital negatives
that utilize digital step tablets.

http://www.huntingtonwitherill.com/

Also I might mention that Mark Nelson, Dan Burkholder, and Brad Hinklel also
use digital step tablets for creating process adjustment curves with their
systems.

So you see they do go digital all the way.

Good luck with your digi-negs,

Don Bryant
