Take it a step further. Create Photoshop actions based on all the black and white presets from the other program. Then create an action set of the black and white film actions so you can back it up out of Photoshop.
Just don't share the action set with anyone else because they haven't paid for the program.
Very likely the "film presets" are simply PhotoShop curve files. And as well also affected and thereby limited by developer effects as the characteristic curve of a film is very often quite different when different types of developers are used.
Ideally to get an effective "curve" file it would require photographing a step tablet, developing the film, digitizing (scanning) the step tablet image, or better reading it directly with a densitometer. Then the density reading can be plotted corresponding to the values of the step tablet to result in a curve. Transferred to a Photoshop Curve as a saved file allows you to exactly linearize the the reproduction of a subject image on that particular film once digitized by scanning and then open in Photoshop.
How to do this and obtain the best printing results, I have found, is discussed and explained most effectively by going to Paul Roark's web site at: http://www.paulroark.com
Larry, thanks for the tip. And fear not - my lips are sealed.
David, I looked at Paul Roark's site before when I was using MIS inks. I'll check it out again....
