What film is this?

[Michael_4514]

An 8x10 holder that I bought has a sheet of film in one of the sides. It has no notches, and it is extremely thin. The absence of notches makes me think maybe x-ray film?

I don't know.

Without notches the only way to know for sure is to ask the person who loaded it.

Thin film could be any kind of Litho/Line film, X-ray film is usually thicker.

X-ray film usually is noticeably stronger than photographic film - it takes a bit of matter to get an exposure from X-rays. It is more likely some process/lithography film - there were quite a few thin versions of these, as base strength is an disadvantage when doing emulsion-up contact copies (as happens when a plate is exposed off an intermediate).

[Mark Woods]

If the corners are rounded it's probably x-ray film. If not, it's probably litho film.

I don't know.

Me neither.

Well, I don't know what it was either, but convinced that it was not worth shooting, I decided to open up the holder and scrap the film. To my surprise it turned out to be an exposed and processed negative. Here it is. Can't imagine why anyone would store a negative in a film holder.

Maybe for students to practice loading :D

Maybe it was inserted as a spacer. That is what I do when I have really thin film stock (lith film), I first insert a empty thin sheet to secure the thin film (and theoretically the film surface is than at the good "level" )

Best,
