SFW = Seattle Film Works, a US company which repackaged 35mm movie film as still film (without removing the remjet layer) to sell with return processing (buy the film, shoot the film, send it back to them for the proper processing and you get prints/slides and another roll of film, and you are hooked for life!!!) – in the 1980s thru the 2000s. Much more info can be found at Wikipedia. The film was usually marked for process SFW-XL (their own code for ECN-2). Late in the business, after some legal issues, they started selling C-41 film.
Well, normally I avoid SFW film for expired-film use due to the ECN-2 issue – but recently in a bundle of old camera/photo equipment I got a boxed roll of SFW 100 that expired in March 92. Out of curiosity I opened it up to see if the ramjet back then looked like now – an almost black, flat, layer on top of the base side of the film. Hmmm – nope, looked like normal C-41 film. I could shine a flashlight all of the way through the leader. Then I noticed that the label on the canister was coming loose.
So I carefully peeled away the SFW label – and voila, this roll is a C-41 roll from a different company. “Chandi Film – Premium Plus” – interesting. Google has not found me anything to determine exactly where/when this film is from, but my guess is probably a brand sold in India?
Now it is in the freezer and I will shoot it at ISO 25 sometime sunny and see what I get.
