I built this hybrid Kodak Box Brownie - Polaroid (Polabrownie) some time ago. I cut the "nose" off a plastic Polaroid packfilm camera (probably a Colorpack IV or Supershooter) and attached the filmpack back to the back of th Kodak 2C box camera. Focus distance is about 3 to 3-1/2 feet, which makes it good for portraiture, like a Polaroid Big Shot.
The photo was taken last weekend in early dusk near a window.
When I heard that the deadline for Glazer's Instant Photography contest had been extended. I grabbed a pack of FP100-C and the Polabrownie and took several photos. It took a few tries to get my exposure right.
Film: Fujifilm FP-100C
Exposure: f/5.6 (widest camera aperture) for 6sec.
