Hmmm. Everybody seems to be of the mind that P30 needs to be shot at an iso slower than box speed it seems. Just developed a roll I shot at iso 64- was not impressed. A lot of overexposed shots! For my development process I definitely need to shoot at box speed. That being said though, my xray processor is breaking down and I won't spend the money to repair it once it's gone. I'll have to experiment all over again....
The grain is almost undetectable, in 120 this is going to be a game changing film.
They've mentioned it's coming somewhere within this thread I believe, but I don't remember seeing a timeline. I'm happy just seeing it in 35mm for now.I haven't been following this closely, buy is this coming in 120? I couldn't find anything on their site about it.
They were supposed to coat a trial batch in 120 format in April. I suspect the factory modifications currently ongoing have delayed that.They've mentioned it's coming somewhere within this thread I believe, but I don't remember seeing a timeline. I'm happy just seeing it in 35mm for now.
Asking a lot from them really. Still working on getting a continuous supply of 35mm. I wish them luck though.
They said they would, one day. Not asking a lot. Easier job packing sheet film.
Well, they've got to make money somehow and selling P30 in various formats might be the way.
Well, we need to give them a break. As I understand it, four years in and they don't even have electricity. Unless I am remembering incorrectly, they have been operating on generators while they wait on the government to rewire the building.Yeah sure I understand, it is just that they completely underestimated what they had to do and how much money they needed. They are still nowhere near making what they first set out to, ie colour slide film. Anyway.
Because these recommendations are anecdotal from various photographers around the world, and not laboratory derived using sensitometry.I'm looking at the DevChart to use D76 and I just noted that ei 50, continuous agitation is 8 minutes, while ei 80, intermittent agitation, is 7 minutes. How can this be?

Thanks for sharing your results! I really appreciate it.These are my sensitometric data.

Here a small review, sorry only in italian, but I think it could be quite understandable using an automatic traslator.
I stress that this work with my workflow in my darkroom and that are exlusively for enlarger printing.
P30 has a long toe and can be used with good results at EI 25, may be EI 50 too if printed on soft grade paper using a diffusion enlarger.
May be that scanners can pull out more details in the shadows than photographic paper, but my workflow is all analog.
Hope it help.

That data will be from successful development reported by users of the P30 Alpha film. It is a "best practices" document, not an official "this is how it should be done".
I used ID-11 (=D76) with intermittent inversions for 7 minutes and felt that it worked better for EI50 than EI80. However in both cases I was able to get good negatives. I only shot two films, one at 50 and one at 80. I think P30 is beautiful stuff but we're still collectively learning about it.
Film Ferrania will tell you they don't have the money or personnel to do the testing themselves. Not sure how you wasted 6 films. When testing, use one film at a time.I get they are "best practices", but there should also be a minimum of proofreading and verification of the data. How can the 8 minute vs 7 minute be? I did 7 minutes in d76 (ei 80) and I got underexposed underdeveloped thin negatives. And it is not the developer, because HP5 developed the same day with the same batch of developer yields very good results. So I switched developer. At the end I ended up wasting 6 films for testing and only 2 with usable images.
Sincerely I don't think that asking for some real, tested development times is too much. I would do it myself if I had the equipment. But now I'm down to my last roll of P30, so I guess the party is over.
I did, more than once. But then I could never reproduce consistently the results in my "real" filma (which I counted in the 6).When testing, use one film at a time.
