Hello APUG from FILM Ferrania (PART 2)

[Mackinaw]

......When I get a few more minutes, I'll respond to questions/comments directly.

What type of chemistry can be used to process this new P-30 B&W film? And how about development times?

I am sure this information will be on the inside of the box, just like any film.


Cheers,
Flavio

Awesome News Dave!
Yes I think this is a wise decision to make use of the tested coatings to on-sell them to recoup costs is a very good move, for the same reasons PE has made.

It looks like my guesses were correct that that first coating was indeed P30! Although others claimed here that it did not look "panchromatic"

I assume this means that the coater is successfully coating film now also without the bubbles etc?

I will be emailing you soon, as I had paid for some extra rolls of colour film on top of my kickstarter reward.
I think I would be keen to grab a roll or two of this from you, so was wondering if i can exchange some of that amount of extra film for some P30

 

[Cholentpot]

Wow. Looks very nice.

Where will a late to the game fella like me be able to pick up a roll or two of this?

Two new films in one month! Looks like film's back on the menu...

 

[DaveTheWalker]

Great news about the film! I've filled in my survey, and will be purchasing some extra rolls of P30 when it's available

I just did a quick Google News search for Film Ferrania and came up with this:

http://www.savonanews.it/2017/01/11...mila-euro-per-limpianto-di-illuminazione.html

Now, my Italian's not great, but Google Translate came to the rescue somewhat. Are the team involved in this project at all, Dave?

 

[Nzoomed]

I think its amazing that P30 could be revived so easily!
Remember all the talk here about EPA banned chemicals etc? In the EU they are pretty strict on such things also, so I would imagine there was nothing really much to worry about.

Very high silver content also, so this is probably a good alternative for those that loved Efke film

I claimed that based on the first shot (the one with the horses).
But after looking at the other sample pictures, it looks as panchromatic as human eyes.
Each frame is a piece of jewerly!

I think it looks pretty impressive from the samples ive seen, but would be good to compare it with the original P30 to compare.
I think its a good marketing decision from ferrania, and I was actually kind of hoping that they would make this film available to their backers as at the end of the day its a piece of history and is the first film that Ferrania has bought back to the market.

My other question is this, i take it that P30 is a positive (reversal) film?

 

[Photo Engineer]

The 5 g/m figure for silver is in the high end of present B&W films but not unreasonable. To me it indicates possible desire for high contrast, reversal processing or perhaps just low chemical sensitization.

P30 is neg film, to be developed with typical B&W developers lile D76. Most b&w negative films can be reversed.

It would be great if it has been designed for good results on reversal processing!

 

[mshchem]

The big deal is these guys gave pulled off a miracle by getting an abandoned industrial park going again. Great accomplishment. It will only get easier with some income coming in. Let's hope the best. Bravo

What does a high silver content mean for a black and white film? I see it mentioned commonly with reversal suitable films but what does it do/change?

If you go really broke you can boil off the emulsion and reclaim the silver. A few rolls will get you enough to buy a few potatoes.

 

[mehguy]

I swear I saw an FAQ about Ferrania not planning on making a BW film a few months ago, I guess they changed their minds

The other thing could very well be the fact that they are following the original formula.
It does not surprise me that its a high silver content.

Well as it turned out, they needed to make a simple B&W emulsion for testing the coater, and they must have thought they may as well try P30, (does not surprise me, as its quite obvious Nicola has been dying to get his hands on the stuff! )

 

[Trower]

I am very excited to give this a try for sure!

See the video I posted above, it has Nicola Baldini explaing why they had made a B&W film.

 

[Peter Schrager]

I think this is fabulous as I never bought into the kickstarter for chrome film. way to go Ferrania!!
damn folks we got film choices!!
best, peter

Early methods of sensitizing silver left dead grains which were useless. These were called "high silver" or "silver rich" materials. As technology improved, the process for sensitizing became better and silver levels were decreased. As they were, grain went up but so did sharpness and thus, they made finer grains at the same speed. (following me so far?). Thus, today's films are finer grained but lower silver with better sharpness and equal or higher speed. Today, about 300 mg would equal 500 - 1000 in days gone bye (mg/ft square).

So, there it is simply.

PE thank you for the clarification! still looking for those silver rich films!! I"m looking forward to try the P30 film but my trusty TMY400 stays in the bag!!

 

[Jeff L]

This is great news. I'm in!
I'll be keeping the reward and buying P30. Form filled out and now waiting for the email from Ferrania.
Can't wait to try the P30 and the E6 (Ferraniachrome?)

This is interesting. Any idea what percent of silver was “dead” in these high-silver content films?

OK, that is interesting to know.

Do you have any idea why the high silver films such as Efke were so popular?
There has not been any other manufacturer making films with such high silver content (probably for the same reasons you mention) for quite some time.
I believe Efke had high contrast, so perhaps this is what people liked, but I expect others will know more who have shot the film themselves.

 

[Roger Cole]

Sheet film version one day would be nice, too!

+1!
