Question to all you techy film folks: If I have a variable ISO film, can I swap ISOs on the fly & still end up with all photos correctly exposed at the end? Say I have a 100/1000 ISO film, if I shoot two at 200, then one at 100, then the rest at 800, when it’s developed, will they all be okay, or will I get some under-exposed, some over-exposed, and some just right (due to them all being in the emulsion for the same amount of time)? It may be a silly question but I’d like to know before I go out & shoot!
To compound the issue further, I had some redscale where I intentionally over exposed one frame, and while the whole roll looked great. Compare this (normal daylight exposure in sun):
…to this (Put in bulb mode & held for 4 seconds):
What about you, smart people? Do you have answers for me?
