Cor -

Any idea where this film is available? I've heard of using X-Ray film
in pinhole and have been looking for it without luck.

BTW, I hold something black, like a slide holder, over my hand as I open
my pinhole shutter. When vibration has settled down, I move the slide
holder away and begin counting the exposure.

Thanks -
