Shanghai GP3 fun/"informal test" using a Rolleicord Vb.
To be short, the film is good, but fiddly. The tonality and contrast seem reasonable, I'm not sure how close it is to FP4, but there is some similarity. The grain is probably quite comparable. As I mentioned earlier what lets the film down, for me, is:
(i) The base, which is a bit curly and somewhat uneven. Quite difficult to load onto a development reel.
(ii) The fragility of the emulsion, which is somewhat easy to damage at every stage in the development process.
(iii) The reels themselves, which are thin, and (though I haven't tried) might be problematic in some cameras.
(iv) The end seal doesn't have any usable gum on it. Obviously one can just use a rubber band (incidentally quite easy to find in the UK, as Royal Mail leave them all over the place).
I developed the film in 1+50 new APH09 (equivalent to Rodinal) for 12 minutes, exposing the film at about 80 ASA. This is probably the optimal speed for my use; going to 50 ASA didn't seem to help the grain or the contrast.
