I have quite a stash of 4x5 and 5x7 Shanghai. I loaded up some of the 4x5 in Graphic Film Backs and shot a still life with my new Broncolor Octobox 150. This is great film IMO, so loading up a bunch more as I have time. I shot my test flash exposures at F16 and F11, and both sets negs could yield good prints. This film likes D23 1:1 in a Unicolor UniDrum. Back when this was being discontinued, this film was quite a bargain. Next I will test the 5x7, and I've been shooting quite a bit the Shanghai 220 with great results.
