re: #7 William Lewis

I really need to dig out the last few rolls of Tech Pan I have out of the fridge and fire up my Canon 7… I just need to borrow a decent LTM 50/2 lens to use on it.

Considering that film was discontinued over 10 years ago, I hope you have it frozen for decent results. I know Kodak always pushed the “no difference between freezing and refrigeration”, with the statement to never use it beyond the expiration date regardless of storage temp, but that was BS and I don’t know any working pro that abided by that nonsense. Aging film hardens and causes the streaking/mottled development with a dash of base fog. Radiation adds more base fog over time. Have fun with that experiment.

OT-
My favorite film was panatomic-X or tri-x rated at 200 and developed in hc100 dil B as a one shot developer. Somewhere in storage I have a box of syringes and pipettes for mixing the stuff. I always found diafine too mushy and a pain to mix. If I needed finer grain at the expense of acutance, I’d add sodium sulfite as a solvent to the developer.

On the easy side for 4X5 was Type 55, which was Panatomic-X, manufactured by Kodak and repackaged by Polaroid.

lol, my first camera was a kodak brownie. My first 35mm was a zeiss viewfinder camera. My first pro 35 was a Nikon F2. My first 4X5 was a Cambo. I still have all of them. Geez, I either feel old around here, or have publicly “exposed” the packrat side….
