In the pictures of the bricks I have placed above; what should I notice?
In the photo with the hammers (that you have quoted), there was nothing red on the table ...
So I take it that there either isn't a published spec sheet which shows P30's sensitivity to the colour spectrum as is the case with Ilford and Kodak films or if there is such a sheet no-one so far replying has access to it?
Maybe Ferrania will supply the new chart on P30's sensitivity to the colour spectrum or if it indeed it replicates the old P30 of the 1950s it will give us the "old" chart. There must be such charts, surely?
Then we can have a debate on whether it is panchro, ortho, panchro-ortho or ortho-panchro once we have decided on the resurrection of Kodachrome, Panatomic X and HIE
.
Just as an "aside" I raised at many referendum meetings in early June 2016, my need for an answer to this question about an Italian film's colour sensitivity without giving much thought to the consequences. Then on the 24th June I awoke to discover we had voted to leave the EU. All I can say is that I did not intend my discomfort at living with uncertainty about an Italian film to have this effect

Pentax, it appears that every single user around the world who sends in an example with development time and temp is contributing ever-so-slightly to the new spec sheet.
I wish I had your optimism. We have seen examples in this thread which taken at face value seem to indicate we should draw opposite conclusions on its red sensitivity. A pity but its a dilemma that can be easily resolved with a chart based on tests.

I don't know why that's a big deal. Remember, this is the ALPHA version of this film; the very first rolls off the line. The data for that chart is still being assembled. As a software developer, I would never let a user see my alpha product. Instead, Ferrania has courageously given us a rare opportunity to play around with a product nobody else has ever touched, or even know exists. Besides, how much are you out, 5 rolls? For that you could get a Happy Meal or two. It's nothing that's going to make any difference in anybody's life.
OK. I had thought that the film was very close to the original P30 from the 1950s and that the colour sensitivity might be very similar or at least its red sensitivity was likely to be very close such that a chart might exist from those days that would be helpful. I hadn't seen anything that suggests that the P30 is a brand new film whereby the final version is likely to be quite different in terms of red sensitivity from the ALPHA version
What is certain is that it is the same P30 that the contributors who have commented on its normal red or lack of red sensitivity have in their possession and I wondered how we could reconcile the difference.

What made me want to try P30 in Diafine? These were test shots taken with my Nikon F100, bracketed, so each frame is at 200, 400 then 100. Epson V500 scans, with all corrections turned OFF. Developed in Diafine, 3+3, at 71F (pardon the mild drag). Draw your own conclusions!
... Draw your own conclusions!
Probably 80 iso !
What color was the roof of the house? Thanks a lot. ;/)

Yes, yet more proof that P30 is about 80 which is more or less what Ferrania says, isn't it. What Ferrania doesn't say or if it does I can't find it, is P30's colour spectrum sensitivity.... Draw your own conclusions!

Good question about the roof. Maybe some kind soul who possesses P30 will take a picture of a Macbeth chart or just some items that are yellow, orange, red, green and blue with white and black thrown in for comparison to put me out of my misery as the saying goes

Funny you should ask. Only difference is it's overcast today (and she cut the grass...).Probably 80 iso !

Every kind of film, once it has come into production, will be available in all formats !!!
Obviously those "normal" ... 135, 127, 120, 4x5 8x10 and those movies;
This was stated in Milan. Saturday 06-10-2017
Wow!! P30 has nice colors! And it doesn't seem insensitive to red!!
Probably because I click with Soviet material ??? Which as we know well, is sensitive to ... red !
Best joke of the month in APUG.
There is no orthochromatic question. If you read Ferrania's advertising it definitely states that P30 is an panchromatic film with an ISO 0f 80 based on their cine film.

Based on bvy's photo of the house with P30, and the corresponding color photo, there seems be reasonable panchromatic sensitivity to me. Far from orthochromatic.
Here are some I took last week.
I developed using D76 1:1, 21c for 13 minutes on a Jobo. I shot at ISO 80, but I typically will overexpose half a spot or so while composing. It was a very sunny day.
I like the film quite a bit, actually. I'm looking forward to using it again.
