First of all, my apologies for typing 0.1 instead of 1.0 as the density I'm shooting for. Thanks, Ann. Now...(posted 8500 days ago)Alec, I should've emphasized that the densitometer readings were NET density. The film base + fog density has been subtracted.
I haven't moved forward with my N-, N, and N+ times yet because I'm not confident that I've found my EI for Tri-X. I'm aware of the full calibration process. I've a fair library of references on the Zone System from Adams, Barnbaum, Bond, Davis, Graves, Johnson, and White. Not Picker
. Could you explain why my setup is wrong? This was the recommended setup in the workshop I just attended. I realize it's an abbreviated form of the full ZS calibration procedure but if the intention is to find the EI where Zone I yields a negative with a 0.8 to 1.2 NET density then it looks correct. Why would I need a full contrast range to do this?
If I sound like I'm engrossed in testing than taking pictures then, yes, at this point in time I am. I'm currently fascinated by the sensitometric part of photography even if my controls are slightly loose. The small amount of information that I've uncovered so far has infused the "art" portion of my photography with more confidence so it's not all for naught :)
