Gee, I wonder where she got those links from...
Anyway, now that I'm on the spot, I don't like using paper in a pinhole or individual sheets of film for that matter. It's just too much hassle to run in and out of a darkroom or keep fumbling through a change bag to get another shot. So, like a true vagabond (you should've seen my luggage last week,) I take cameras made to use regular film and tweak them into pinholes. That way, I can shoot and shoot and shoot without needing a darkroom, etc, between shots. I can also just dump the rolls off to be developed like any other film. Bada bing.
All that said, I love Ilford HP5, to the point that thinking about the grain gets me all flush. But anything 100 speed or so will do, as long as it's Ilford.
I use a second or so for exposure, it's not rocket science right? For color, I use whatever is cheap and slow, like 100 speed Kodak.
Go to a thrift store, spend a buck on a 35mm camera, crack it open. Figure out how it works (not rocket science, remember) and remove the shutter thing, which is just usually a piece of plastic attached to a spring. Now you have a hole. Make a pinhole out of your favorite beverage (
) and center that baby over the hole where the shutter once was. Viola! A self winding pinhole. Use a business card taped to the front as your new 'shutter.'
Work smarter, not harder friends!
I'll post an explicit example of this sooner or later. I have a few rolls to finish burning.
Oh, if you want to get precise:
