Minolta X-300, Rokkor 1.7/50 open stop, Fuji Acros100 @ 1600(!), Caffenol-C-M, crop 15x20 mm neg size, scanned with Canoscan8800F and Vuescan, edit with The Gimp.
The Acros 100 was exposed at EI 1600, developed in Caffenol-C-M for 20 minutes at 21 °C. I added +10 % of each ingredient. The neg is thin and needs some edit work. I would not recommend this 4 stop push for daily use. But not too much noise and very small grain here. Probably the smallest grain I ever saw with a 1600 ASA exposure. Watch the bigger size!
