Curve evaluation questions

[menglert]

I made two curves with PDN for Foma & Fotokemika B&W papers to practice before I do Kallitypes. I would like others opinions because I'm not sure if
the green line should more closely match the blue, or if this is
sufficient.

Martin,

Based on my experience with Curve Calculator I that is a very good adjustment. Make some prints and see how they look. You may need to do some tweaking but you are very close. Good work.

Hi there,
Nice looking pics. What exactly is this curve calculator, is it a excel file generated or is it an actual program?
Thanks
