SVEMA FN 250 USSR Soviet Union Russian B&W 35mm Negative Camera film

hello so I want to talk about a special expired film which is a Russian film from back from the Soviet Union time and it's called as Emma 64 it's it's a cool design vintage box and I bought that from Ukraine on eBay for a few bucks the interesting thing is it's a it's very slow film it's a 64 easel or easel now as we say and it's it was expired in 1994 so it's just before the just after the collapse of the Soviet Union I would rate although I'm not that precise in my history but anyway coming back to the film when you consider shooting all film in black and white you would have to say it's losing its sensibility sensitivity over time and that's about one 1/2 stop for ten years so 25 years what would make maybe one and a half stop and you can do that by changing changing the days are on you are on you are on your film so that you can pretend that it's even slower as it is so dividing by
