This film was returned from the lab. My least exposed shots are the only ones to show decently. Good thing I bracketed and then experimented even more in low to no-light. The interior at f1.5 was overexposed. It must be 320 Asa. Twilight out of doors of lamps by a garage door show all the details in the dark edges, then later, and even darker, another exposure even looks good. The film edges are a light gray as is the leader, much lighter than I process, I project my films, This looks like it is made to be scanned, not projected. I can not even come close to duplicating what they did. Should have been very hot and very fast. My hot and fast resulted in totally clear film. 98 F and 30 seconds. 88 and 30 gave faint images. I got it to work though at other ways. No other markings appear on the film other than the numbers every 20 frames. 400 and 800 ASA are now in my tool kit with this film. I shot bright sun at f22 and 64 fps today to process after I buy more chemicals.
