I’ve been doing some research online about stand development with D76. Most of the pages I’ve read tell me to use Pyro or Rodinal because D76 is not suitable for it. I’ve read about people using D76 with TMX or TMY with successful results, but not with Tri X. Since I was bored and D76 is all I had on hand, I decided to try the D76 and PX combo. It worked beautifully. I am not going to tell you why there are times you may have to use stand development, please research thoroughly on your own.
- Mamiya 640 PRO / Sekor
- Stand Development
- Kodak Plus X 125 (120) Exposed at 125
- Kodak D76 1+7 (18oz Fluid Total) (To be specific, 1 part developer and 7 part of water, so it will be 18/8 = 2 1/4 oz Developer)
- Presoak (Well I did what I call ‘Pre-wash’ like I do with everything else. I wash till its almost clear to swell up the gelatin and get rid of the majority of the stain)
- D76 was at about 21C when started. Room temperature was at around 23C.
- Time: 1 hr 5 mins.
- Initial agitation: 10 times
- The Tank calls for 18oz but if you can fit 19 or 20 in there go for it, so the edges will have less chance for air bubbles, and you have more working solution also. I would also recommend the same volume for 135 film.
- -Open the lid of the tank so the developer will go back all the way down from the top after initial agitations.
- Make sure you tap the tank very well to get rid of the bubbles afterwards.
A fellow reader did his own experiment with T-MAX based on this info.
“and it worked. My negatives (Tmax 100) were of Norman Koren’s lens test image (vertical lines) Thanks for the post on d76 “stand” processing. I used your 2.25 oz D76 suggestion increasing lines per mm). On the negative, there were resolved at least 48 lines/mm, close to the value expected from the Kodak data sheet.”
He also further elaborated on his procedures:
“The way I measured the highest resolution was simple:
- Photograph a test pattern consisting of vertical lines at increasing lines-per-inch
- Scan negative (at 9600 dpi in this case)
- Set Photoshop ruler to pixels and determine the number of pixels between just-resolved line-pairs (8 here)
- resolution = 8 pixels / 9600 pixels-per-inch * 25 mm-per-inch = 0.02 mm-per-line-pair
the reciprocal is 50 line-pairs-per-mm.”
A big thank you to Mr H. Cohen (Nov 2012).
