So, I bought a Watson film loader off eBay and it came pre-loaded with some unknown type of film. I'm almost sure it's fogged, but I'd like to try using it anyways. I shot a roll of stuff around the yard, so it's not important, but i wanna try to process it. How would you guys recommend I process it? Is there a way that I can develop a bit of it without any images on it to see what speed is written on the edge of the film? What do I do?
