I prefer to derive a curve that is applied to the negative image. I
haven't been doing this very long, but it makes more sense to me to see
the adjustment to the negative image on the screen as I can envision how
the manipulated negative file will print. As Darryl has related, the
adjusted positive looks terrible and I don't make the same connection as
to the result if I'm looking at the curve-corrected positive. Either
method will work, but you will need different (inverse) curves.

I also set the curve dialog box to have the dark areas at the bottom
left so it resembles a standard H&D curve. That also makes it easier
for me to envision the result, but some worker's curve boxes I've seen
have been set up with the highlights at bottom left. That just mixes me

You can also do curve corrections in the transfer dialog box of the
print menus.

Gary Nored's site discusses the opposite approach, applying a curve to
the final neg
instead. Here's his page:

Of course, applying Burkholder's curve to the neg instead of the
positive is going to
make it a different curve. Anybody who's done this both ways, that could
offer some
insight or feedback?

positive... it will look awful, but print fine

Subject: Digital Negative Question

I have made my first digital negative using Pictorico OHP and contact
printing onto silver gelatin. Results were encouraging and I will now
try some alternative processes. But I do have really dumb question. I
have downloaded the "curves" from Dan Burk holder's sites but have a
question regarding use. Do I apply the curves to the positive image
then invert or invert and apply the curves to the negative?

Thanks in advance
