Hi All,
I'm currently working on a darkroom software which calculates the final print from a scanned bw negative, and shows it on a computer screen.
The idea is as follows:
1. Make test strips on your photographic papers.
2. Scan them, measure the densities for each strips. Draw the characteristic curve.
3. Scan a negative.
4. Apply the curve on the negative.
Here's some articles on how can a scanner be used as a densitometer (I'm using an Epson PhotoPerfection 3200 and have checked it with a Gretag densitometer)

And here, you can download the application:
http://www.geocities.com/talajmente/LightRoom.zip
(zip contains an .EXE, a test image and a PaperTest.csv containing some sample paper tests)
It's the very-very first version and have not been tested in the darkroom yet.
If you want to try, test, have any comments, ideas, bug report etc...
Thanks,
- Lajos
