First Roll of 120 B/W

[unohuu]

I finished and processed my first roll....J and C Pro 100 in Rodinal 1+25 for 8.5 minutes. The images were made on Mamiya M645 w/150mm f/4 and +2 diopter. Took the best to Pro Color for a proof print. Hope to see them soon. It was an orchid that has found its way to my space. I water and watch it grow. Today the light was soft (cloudy in Minneapolis) and the new blossom had just opened. I finished the entire roll bracketing f/11 -f/32 and speeds of 1 s to 4 secs with cable release. The negatives were perfect, except for a scratch on the negs that should have had MLU when shooting. Luke

Sounds great. Did some JandC 200 4x5 in Rodinal and was very happy with the results. I understand that the 100 is a different film but I don't know the differences aside from the speed.
Post your results to the gallery when you get them back, I'd love to see them.

Neal, the most recent posting in my personal gallery, "Frosty Morning Calm", is from Pro 100. It's a completely unique film, custom coated for J&C on very old equipment in China (the Classic 200 and Classic 400 are rebranded Forte). I like it a lot, but it's a soft emulsion, and benefits by avoiding temperatures above 68 F and sudden shocks from alkaline to acidic (so no acid stop bath); it also scratches very easily.

That said, it's the only ISO 100 film I have around; at the price, I'm willing to put up with the black backing and framing numbers printed in (sometimes rather thin) white ink, the very soft paper of the backing, and the lack of a useful end tape (I either use the masking tape that secures the new roll, or if it has too much black paper stuck to it, a fresh piece of masking tape; either way, I stick it inside the door of the camera so I'm sure to have it handy when I unload). Grain is fine, even, and crisp, tonality is excellent, sharpness and resolution quite good, and at least in my process, speed is exactly as rated. It's even got good latitude; hard to argue with those qualities in a film that's $1.39 a roll including a black film can.
