When I taught a two-week photo class to kids (7th to 12th grades, mixed), the first day we made pinholes cameras, then exposed litho film in them. Continued doing so the second day. Then three days of cyanotypes from the litho negatives. Film cameras (35mm) the second week...but we used Ilford C-41 B&W film and a deal with the local camera store to process them. Two days to shoot, three days printing 8x10's. Lots of fun! But it has been years. Have fun, Andrew!
