Shooting with a 42 year old 120 roll of Kodacolor; exposure index?
So I'm planning to go out and shoot this super old roll of film in my Yashica Mat 124 sometime soon in the future, perhaps to do some night photography. I have no idea what the results are going to be colour-wise but I guess that's the fun of photography!
When this film was sold in 1960, it had an EI of 32. I've heard that even with good film storage in a freezer (which is what this film has had since day one) that the film could lose as much as one full stop of EI/ISO every decade. I have been struggling to figure out at least a good estimate of what the EI/ISO would be today so that I can meter accurately. Any ideas?
