Hasselblad H1, 80mm 2.8, Shanghai GPX100 220, DF96 Monobath.

This time I had the monobath at 70, not 75, and there was far less damage to the emulsion.

Just bought some more off Amazon - which is by far the cheapest source and has next day delivery. $13/roll

Time to revive the thread about Shanghai 220. Who has used it recently, and did you detect any flaws, emulsion issues, or faulty tape on the leader/trailer? Any comments? I see it advertised on ePrey at a decent price including shipping from China to USA. Thanks!

No issues. Check Amazon first before you go the ebay route.
5 rolls for $66, next day delivery.

After processing 3 rolls of GP3 220 I come to the conclusion that this film is a very close relative of the FOMA Pan 100.
The real speed of the material is about 50 ASA, the graininess corresponds to the FOMA Pan 100 and also the graduation in the highlights corresponds to the FOMA PAN 100. Both films react indentically to a development in PMK (same amount and color of stain).

Please post examples as I have found that it is perfect shot at ISO 100.

I just processed a roll in D-76 1:1, it's drying now but it looks perfectly exposed, maybe even slightly over. I exposed at ISO 100. No stuck papers and it fit on the reel. The scan will reveal if there are any short comings.

Prewash dumped out and it was the prettiest shade of blue.

However it is Filmotec who presented in their plant the GP3 amongst a range of their products.

The 135 version of the film is original filmotec UN54. I use this film since many years.
The 220 version I tested now is totaly different. It shows exactly the same sensitivity, contrast and gray scale and graininess like the FOMA 100.

The tests had been done using the following equipment:
Bronica SQA - PS 2.8/ 80
Zone VI modified Pentax Spotmeter
Paterson System 4 tank
Heiland TAS Filmprocessor
Heiland TRD 2 Densitomerter
Zeiss microscope

That's what I see. The exposures are perfect at ISO 100.

It is indeed! And much better to find out with test rolls, than shooting a project and then ruining it!

I think Shanghai should note that on their packaging, or at least provide a list of recommended developers.


which developer did you use, then, in the end?
