I’ve shared photos from this roll of Agfa CT Precisa 200 before (see When Expired Film Goes Bad), but at that time I did not know the cause of the spots. I thought it may have had something to do with the age of the film or poor storage conditions. I was partially right. I have since learned that the spots are actually caused by a fungus that can infect and feed on the gelatin layer of a film’s emulsion. The fungus/mold is often visible on an infected roll of film (before shooting) and may appear as white spots. Sadly, there is nothing that can be done to reverse the damage once the fungus has burrowed into the emulsion. The only way to prevent this kind of damage is to ensure that film is stored in cold and dry conditions. High humidity can promote this kind of fungal growth.
