Osiris — F1 Film Developer

Osiris F1 won't make you a better photographer. But it will stop you from blaming your chemistry for flat negatives. Give it a try—your scanner or enlarger will thank you. Has anyone else tried Osiris F1? What’s your dilution for pushing Delta 3200? Drop your times below.

Also, shelf life. Because it’s ascorbic acid based, once you open the bottle, you have about 6 months. It oxidizes faster than phenidone-based developers. If you shoot one roll a month, stick to Rodinal. If you’re a heavy shooter, F1 is fine. osiris f1 film developer

Osiris F1 produces what I call "structured grain." It’s not the invisible, plastic-y grain of XTOL or DD-X. It’s also not the volcanic, artistic grain of Rodinal. It sits in the middle. Under a loupe, the grain looks tight and sharp, like fine sandpaper rather than jagged rocks. Scans come out looking detailed without requiring heavy sharpening in post.
