    Yes, look out for nitrate based film. BAD stuff, and a potential fire hazard.

    Probably not (unless the photographer had used decades-old film bought off ebay .) "Safety film" was introduced in the early 1900s. The movie industry didn't completely switch out until right after WWII, but consumer film for still cameras had been cellulose for a long, long time.

    Cellulose acetate, to be clear (ew, bad pun), as nitrate film is also cellulose.
    I do use a digital device in my photographic pursuits when necessary.
    When someone rags on me for using film, I use a middle digit, upraised.

    StoneNYC recently got a stash of films dating as late as 1947 with no edge markings.

    I advised him to be careful as it might be the Nitrate based. He gave it a "safe" ignition test and it went up in a flash. So I'm looking at some information that says roll films used it even in the 40s.

    This comes from a PM, but since it is critical to know for safety, I thought I would bring it up.

    What to look out for with old negatives

    Hey guys, can anyone help me identify this?

    I developed 3 rolls of old film together, a roll of technical pan, roll of "recording film" and roll of Panatomic-X all Kodak, the Pan-X was easy because it has "Kodak Safety Film 5060" on it so the number identified it, the other two, one says "Kodak Safety Film" only no numbers, and has some fog like the pan-x but the other one just says "Kodak" and is SUPER CLEAR no base fog at all, so I'm really hoping that's te Tech pan, since recording film was fast 1000ASA and SHOULD have fog, but I got the tech pan off ebay cheap and it didn't look well stored, boxes all beat up, but anyone know which is which? PE??

    Panatomic-X



    Kodak Safety Film???



    Kodak???



    Thanks anyone!
