In an attempt to identify the type of "mystery film" I bought and mentioned here, I would like to do some tests.
1 – Can I take multiple pictures on the same roll with a different ISO setting on the camera, then see which one stands out the best? (Or should I shoot whole rolls with different ISO settings?)
2 – Is there a way to "guess" whether it's color or black-and-white by trying different settings in the camera?
The first roll that I shot was treated in black and white and came out very contrasted. I liked the results, but I am curious to try to test the film because I often buy unbranded / unlabeled movies.
