The standard convention with rightward shift of the H&D curve is a slower film. In this case about 3 to 4 stops slower.Could you give a brief summary of what that curve means? Specifically, how do HP5 and Shanghai negatives differ when you print them?
I have 25 sheets left and will continue to use it. It has not yielded excellent prints with all scenes, but for the price it is very good.So, do you like it?
I set my meter to 3 stops more exposure than I previously determined for HP5 from in camera tests, based on the film curve above.I've been shooting this film in same format for a few years now. EI 50 in Pyrocat-HD. Once you get the shadows higher up on the curve, they become more open. Did you expose these at box speed?
It looks like beautiful stuff. I bought a box and I've loaded some in my film holders for me to test. My first impression while loading the film is the film base is thinner than other 8x10 film. I've tried Arista EDU 200 and the film has a nice look. But the reciprocity sucks. I think Shanghai has better reciprocity failure than Artista 200. My preferred developer is HC-110 (B).
Agree with all this.It's a lovely film, but Shanghai has the worst reciprocity that I've seen from the many films I've used. For example:
An 8 sec metered exposure with compensation becomes 30 sec, with a 19% decrease in development. For HP5, an 8 sec exposure is only 12 sec after compensation, with no adjustment to the development time.
Thanks for your input! What I find with long exposures with reciprocity failure is the long exposure is for the shadows but the highlights gets blown out. I've tried using semi-stand development to tame the highlights. Ilford 8x10 is great film, but it's $6 a sheet. But Shanghai and Arista EDU 200 is about $4 a sheet. I think for long exposures, Ilford is the way to go.with no adjustment to the development time.
