I recently found a Nikon EM and a Pentax K1000 in a box in my grandmother’s attic. She gave them to me as a goodbye gift. I was wondering if anyone has experience with film cameras. Just a basic how-to. I know there are different ISO films, but that’s about it. I have a 50mm on the Nikon with a 2x teleconverter and a 50mm on the Pentax. I obviously know shutter speed and aperture. I mostly need help with the film choice, how to take care of the film, where to get it developed, how to properly change films, and the modes on the cameras, etc.
