I posted a video and blog article about making pinhole cameras from photo storage boxes, which are an inexpensive and easy method of getting into large format pinhole.
By the way, besides describing a simple and effective pinhole camera, this entry describes two of Joe's innovations that are really handy:
a simple "platform" to hold a camera on a tripod, with cup hooks and bungee cords.
the idea of having a divided storage compartment in the back of the camera.
I've "borrowed" both of these ideas from Joe. I use my platform often with lots of different cameras. It took all of 5 minutes to make and is very useful.
Thanks for that presentation Joe. I really liked the 'inner storage box' 5X7 concept. With this system one could pack a complete set up in a medium suitcase with trays, chemicals, contact printer, and other necessary stuff for a extended vacation. I see Freestyle has their RC grade 2 5X7 in a package of 250 sheets for $76, even with shipping that is about 70 cents per print for 125 prints, not too shabby.
I usually pick up a couple of new camera boxes during the Christmas season. Cookie and candy tins are my favorites, and the big popcorn tins are useful, too!
