Hello,
?
I would like to start using digital negative for silver gelatin prints, printing on Fomatone Multi-Grade papers which I use for my work.
I have no experience with DN and would appreciate if anybody can help me with answering following questions...
?
1) I wonder if QCDN could be used to adapt its Ilford starter curve to this, or any other MG paper. Or do I need to consider the Pro version to built curve from scratch since my paper can behave totally different?
?
2) I try to read up on the whole process of creating DN but I got confused by QCDN documentation on Establishing Your Base Exposure page with following text:
?
...
Start with a grade 0 or even 00 filter to activate the low contrast emulsion and then use the magenta inks along with the gray and black inks to activate the high contrast emullsion to reach a full range of tones.

I think I understand the logic behind determining base exposure, blocking density, starter curve and and its subsequent linearisation however I am not clear on -
?
2a) whether I set my enlarger to grade 2 during the whole QCDN calibration process and then just use enlarger gradation to control the print contrast.?
?
2b) or whether there is actually no need to play with gradation since any contrast is set in photoshop when making DN and using correct curve it nicely translates to the print and no further contrast adjustments are needed (but still G2 is used for calibration).?
?
2c) or if I perform calibration using low-contrast grade (as suggested above, 0 or 00) and then somehow combine it with adding magenta into the mix to achieve different contrast?
?
I am sorry if these questions are out of place or just plain stupid. I feel I need to understand how playing with magenta inks relates to DN curve I assume gets primarily created with K, LK, LLK inks and how it all relates to gradation of MG papers.
?

Petr
