I was able to get a gorgeous APX neg with semi-stand development using the following process:
I shot the exact same scene twice. The first was processed normally, the second with semi-stand.
The only thing different than the disaster I had over the weekend is the camera/shutter, but I doubt that's it since both shutters fire
reliably and cleanly. I can only attribute that failure to one of several possibilities:
So, as to possibility 2 ... what IS the working capacity per liter of Pyrocat-HD and how/does that change when doing semi stand? Any thoughts?
The neg looks marvelous wet, but I'll need them both dry to compare.
Thanks to the many who provided helpful suggestions here.
- Pyrocat-HD 1.5 : 1 : 150 (20ml : 13.33ml : 2000ml) @20C
- Film in Kodak hangers
- 5 min presoak in running water
- 90 sec gentle agitation - 4 dips, tilt left, 4 dips tilt right
- At a nominal 10 min (really more like 11:30) 4 dips, tilt left, 4 dips tilt right
- At a nominal 20 min (really more like 19:40) 4 dips, tilt left, 4 dips tilt right
- Complete @30min into running water for 30 seconds, and then into TF-4 for 5 min, 25 min wash

- I mixed the developer in the dark by pouring premeasured Parts A & B into the tank with 2L of distilled water. It's possible I "missed" with one of the parts while pouring in the dark and the developer was never properly provisioned.
- 2L of working developers in a Kodak 1/2 gallon rubber tank isn't enough for 8 sheets of film.
- Upon inspection of the camera used for the failed tests, there may have been a bad light leak when the front standard came lose from the lensboard housing on my Wisner Technical. I could not determine if this happened before- or after shooting, but it would explain the washed out negs.
