Well, I've seen 'chocolate prints' (or so referenced as far as I know) done using 8x10 and 20x24 Polaroid. The chemistry is similar, taking a sheet of color and processing it to a bw negative sheet (or do I have the backwards

?). Since the larger format Polaroid pos/negs are not married until after exposure, it's an excellent way to experiment. When this Chocolate film smaller pack was first talked about (here I think?), I was very intrigued. The larger chocolate prints I've seen have never had a pinkish cast to them. They were a richer brown print.
Anyway, I love the shots here, and funny calibrations aside, it is really a nice result.
