I just finished my first roll of Neopan 400 and have some odd, inconsistent frames on the roll. The first shot here is very contrasty, and a lot of the middle tones seem to be blown out (it wasn't THAT much of a sunny day). Many of the other frames look OK, others look like the goose here. For comparison, the second shot is from a roll I shot today with the same camera in this same developer, but I used Tri-X, a film I am very familiar with. Does the Neopan just have trouble handling certain sorts of lighting? Or is my developing protocol wrong?
Here's how I developed it. My usual mix is TD-16, but since they sent me twice what I ordered I decided to half the 2 packages of powered chemical and mix up one half of the stock solution. Yes, I am aware that you aren't supposed to do this, but the roll of Tri-X that I developed in it today turned out just like it was supposed to, so I must have got the amounts right. However, I did develop the Neopan just 3 hours after mixing up the fresh batch. That's something I would never do w/ D76. as I always wait 24 hours to use it, but the folks at Photographers' Formulary assured me that I wouldn't have to do that w/ the TD-16. Now I wonder about that. The Tri-X was developed after the developer had sat for 24 hours after mixing.
I used the same developing protocol w/ the Neopan as w/ the Tri-X. Both films were metered for ISO 250, a yellow filter was used (the camera's meter always takes care of the filter factor quite well), and I developed them for 8 1/2 minutes at 68 degrees in the full strength stock solution. I've developed dozens of rolls of Tri-X like this, and w/ that film I get great negs. I fill the tank w/ the developer, initially give it 30 seconds of inversions, then 2 inversions every 30 seconds, and none the last minute. Stop bath is 10 seconds of inversions, 30 seconds of sitting. Kodak Rapid fixer is 30 seconds of inversions, 2 inversions every 30 seconds, and it gets 5-6 minutes in that.
The Tri-X looks fine, but the Neopan has inconsistencies. Any ideas? I'm thinking that the developer was still too active right after mixing it, but I don't know if I developed, or shot, the Neopan right either. Sorta confused as to why some of the Neopan looks fine and some doesn't. It sure is a lot sharper and finer grained than the Tri-X!
