Thanks to all for walking me through the evidence, *it just clicked* - these corners developed unevenly because of the way I was rocking the tank back and forth. For the first two batches I ran (22...

Fred, I also shot color negatives in many of the same places, just re-cocking the shutter and putting another holder in, and none of those have the same fogging issue at all. To me, that indicates...

Hey Kevin, I appreciate the feedback. I look forward to someday having my own tray setup and practicing development by inspection. For now I'm on the move so much that my options are pretty limited!

Hi Fred, here is a quick snap of the negative on the light table (please ignore horizontal bands from florescent backlight). The borders masked by the holder are crisp and unfogged, so if I...

Hi Pat, no I did not do a presoak. I thought a presoak was to soften the emulsion for the developer to start working as soon as it came into contact with the film, and did consider that it could...

My last batch of processing revealed two possibly separate issues in the negatives. I did a bit of searching around the forum and believe I know partially what's going on. If anybody else wants to...

Thank you for your response. I am going back to inversions for roll film.

However, the swirling technique has worked well for me when loading sheet film into tanks using the 'taco' method since I...

My example is roll film, but I believe the topic of sufficient agitation applies to all formats.

I processed 120 Neopan Acros with Pyrocat HD diluted 1:1:100 with roll film in a tank successfully...

Just a quick update, the rewashing worked and I was able to dislodge the particles. I will be paying closer attention to make sure none of this stuff gets dried on the film in the future though!

Doremus, I'm using glassine sleeves. One thing I noticed about the Arista Ultra 200 after I finished the box and saw the paper box and plastic light proof bag in the light was a lot of dust and...

Willie, the specks are adhered to the emulsion side. I use filtered water but not filtered chemistry. However, I mixed both the pyro and fixer in clear graduates and did not see any debris.

Does anyone know what contamination causes orange spots like those in the attached negatives? They're about 2-5mm across.

Here is some background that may or may not be pertinent to the issue-

Jac and Jim jones, I'm actually not positive it was 4x5 and not 9x12. I had to buy it out of a friend's stock since I had none the day I tested the holders. So that could be it.

I hope it didn't...

Hello all,

This is my first post here. Ive used 4x5 for the last year and a half and often refer to the discussions that take place on this forum as they are a great resource of information. Now I...
