The Santa Barbara 4x5 wooden camera is a very simple box camera. It comes in three different focal lengths. I have the widest angle. For these shots I used "paper negatives". This is using darkroom photo-sensitive paper as the negative material instead of film. It is a lot easier to work with and is well adapted to pinhole. The paper I used was over a decade old, but had been refrigerated. It appears to have a film speed of about ISO 8. The negatives were processed in Dektol and Kodak Rapid Fix chemistry, washed, dried and scanned. .
