I saw a guy in Kenya 10 years ago, using a homemade 8x10 and photopaper as film. Underneath the camera he did a quick develop and fix in a wooden "dark box". He then got the "negative" photopaper sandwiched with a new photopaper, and held it in broad daylight while counting out loud. After that the sandwich returned to the box and some minutes later he presented a photograph.
Some of them re-photograph the 'negative' by placing it in front of the camera. The cameras I have seen have the chemistry inside.
