So I shot a roll of Kodak 50D and 200T while on faction in mexico and recently sent the film out for processing and scanning. Yale Film and Video did the the work and called me when they were doing the telecine to ask if I had gotten my film wet since it was showing spots across both rolls.
They checked the rolls that were processed before and after me and said the issue wasn't present and it was just my film. According to the lab, the spots were present on the emulsion side of the film if you examine with a loupe.
I did not get the film wet so I'm not sure what happened? Screenshots of the issue are below. The spots move around so its not a lens or filter issue.
My theories are: humidity? heat while film was in camera and in my backpack in 100 degree mexico melting emulsion? grease from the camera gate? the film got wet while in the mail? condensation after removing film from fridge before loading?
Any help would be appreciated
