As a part of the pinhole week (or is it month?) that Oaxaca Estenopeica has been organizing for the last eight years, I was invited to offer a class on caffenol at CFMAB at the end of April. Clearly, the sensible plan was for us to make large cardboard box cameras that would produce 16x20 inch paper negatives. So that's what we did. No lives were lost. (In fact it was great fun.) At the end of the week we hung all the negatives up for the WPPD festivities. It was over way too soon. (click any image to enter slide show.)
