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....

Not everybody. :smile: 1/2 my roll at 50 was accidental, the rest were at 80.

I shot one at 80 and one at 50, certainly neither was over exposed. Some people would argue the first was under exposed but in both cases I got some truly lovely images. I developed in ID-11 stock, small tank with inversions every minute. The grain is almost undetectable, in 120 this is going to be a game changing film. I hope it comes out at a reasonable price in 127, because I have a simple Ferrania Tanit 127 camera that I could bring back to life.

I haven't been following this closely, buy is this coming in 120? I couldn't find anything on their site about it.
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 were supposed to coat a trial batch in 120 format in April. I suspect the factory modifications currently ongoing have delayed that.

They said they would, one day. Not asking a lot. Easier job packing sheet film.

One day, one day, like 4 years after they said they would get that colour film out to their backers but still that one day is not here...

Well, they've got to make money somehow and selling P30 in various formats might be the way.

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.

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.

According to Dave Bias they actually didn't make any money selling the first batches of P30. But they are now looking for bigger investors than the Kickstarter.

Yes, the building is currently without power and the local government is still doing renovations. But....Dave Bias has also told us that when P30 production resumes they are now in a position to produce the final product in house without having to rely on an (unreliable) partner to load the film into cassettes and put those in boxes....and he confirmed a while back they were working on getting their equipment for producing film in 120 format into working order. As we know, timelines don't always turn into reality so it's best not to put a target date on this...but P30 in 120 would be pretty amazing stuff.

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?

Because these recommendations are anecdotal from various photographers around the world, and not laboratory derived using sensitometry.

Exactly what I think. Too bad there is no real sensitometric data, this is the real party killer for me. I could not reproduce results with two rolls. I guess others are more lucky than me, but I give up.

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.

Grazie mille Diego! Sono Italiano quindi la recensione it Italiano non è un problema :smile:
Your review is very appreciated, I too work only with an analog workflow (I just use the scanner to make previews to share with friends). I too had good results at ei 25, and I found it frustrating that apparently I just end up with underexposed and overdeveloped negs @ ei 80. The charts are appreciated too!

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.

Thanks for sharing your results! I really appreciate it.

I didn't have all that much P30 to expose but I also found it to be a slower film than expected. I didn't try EI 12 but found results at EI 25 and EI 50 were producing better results than EI 80 for me when wet printing. It will be fun to continue the fine tuning when this film comes back to us.

This. Not everyone completes or even shares density data because it is very specific to equipment used for the test.

With the original developing chemistry not available yet, people use off-the-shelf developers to obtain a look they like and donate the recipe to the sheet along with some sample scans and any techniques used in post processing.

What I "see" using ISO 25 or lower, is more like pull processing to obtain fantastic shadow detail and curtail the highlights, which would be true for many films I suppose.

I'm not as experienced as most here, but it's my two cents from reading and viewing results since the P30 alpha was made available. I have only made 5-6 prints and they were immediately stolen as gifts for friends. :smile:

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.

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 did, more than once. But then I could never reproduce consistently the results in my "real" filma (which I counted in the 6).
My photography is not particularly good and I don't call myself an expert. But normally I can obtain consistent results. This is why I'm so frustrated with this film.
