Yeah, film photography is both a source of big frustrations and satisfactions. I still have to do my tests, but I also found the solution for Zone VIII. I carefully read the Fomabrom Variant 111 datasheet and it states that grade 2 filtration has an ISO-R of 90, which is slightly lower than...

I think I spotted the cause of one of the two problems: my negative readings are affected by Callier effect. This has an increasing impact on negatives more dense than 0.6 - 0.7 and almost no effects on the thinner ones. By diffusing the light, it looks like the highest densities decrease by a...

Good evening, everyone, and thank you for all the advice—it's all very much appreciated. In particular, I want to thank @Doremus Scudder because I think he has touched on a couple of interesting points, and I’d like to respond to them one by one. First of all, my ideal zone scale should be...

Yeah, I agree, they're strange. But... I started with common times found on the web and I got very dense negatives, so I started reducing the time and then, close to the 5 min "safe-area" treshold, I started diluting more. I have a similar problem with home-made D76 (too much density for...

Thank you @bernard_L . The angle of acceptance is entirely covered by the negative frame: I use the enlarger as a controlled source of light, I could use any light. I just project the light and put the negative directly on the light meter, over the cell. However my goal is not to have a "true"...

Good morning, everyone. I'm trying to improve my knowledge of photographic materials, unfortunately without the use of a densitometer. So, I'm conducting development tests using Foma's Rodinal with FP4+, experimenting with different times and dilutions. I use a condenser enlarger with a warm...
