I am a procrastinator. I took photos of my infant son when he was one day old. I used Tri-X in a Nikon F camera using ambient light and no meter, in the hospital. My son is now 18 years old. My note on the film canister said "push one stop".
I have started doing more with film lately, so had gotten some chemicals and got out my darkroom gear. The roll of film is now hanging up to dry. It looks printable, but I am a little out of practice evaluating negatives.
I used Rodinal 1:75, water stop bath, and Kodak Professional Fixer (it has hardener in it). I used a plastic processing tank. All chemistry and filtered wash water was chilled to 15 degrees C. I put the Yankee tank in the refrigerator before loading the film. The room temperature is about 21 degrees C.
After about a minute, I inverted the tank 3 times. Total development time was 56 minutes. Agitation was very minimal, almost none. The developer had reached about 16 degrees by the end. The chilled stop bath only took about 3 minutes. I left the film in the fix for about 12 minutes. Gentle wash was about 10 changes of water over about 15 minutes. The last couple of wash baths had a few drops of Photo-Flo.
I was nervous about developing this old exposed film. I don't have an enlarger set up right now, so will probably get these printed somewhere locally. They look good to me so far.
