i'm looking into getting some tin type supplies from rockland colloid (www.rockaloid.com)
i want to put them directly into my camera and expose them that way, as opposed to doing it in the darkroom with an enlarger.
has anyone done this before? what approximate ISO would it be? i don't want to burn through 15 exposures just trying to figure out what speed this 'film' would be.
thanks in advance!
