Film Ferrania p30

[Raghu Kuvempunagar]

Sure the kit is optimized for Foma R 100, following it to the letter you'll have fantastic slides.

Surely it is optimized for Foma R100. MSDS of the reversal kit makes no mention of any halide solvent in the first developer. It might not work well with films such as Delta or TMax. Delta 100 is not a film optimized for reversal process and yet "it's handling of deep blacks and bright whites is unsurpassed through dr5". Would be nice if someone who has used Foma R100+Foma kit and Delta 100+DR5 can compare the results.

I know of one person who managed to get beautiful results out of Fp4+, Delta 100 using a modified Ilford reversal process. It's viable but with much trial and error. Certainly not using a ready made kit.

Thanks for the information. It is good to know because I have a Foma kit on my shelf I've been waiting to try out. It looks like film and process have to be matched.

@wyofilm, can you please tell me, where did you get the Foma reversal kit in the USA?

B&H has it, but they won't ship it, so no help to me.

 

[runswithsizzers]

The process is the Foma reversal kit, the only chemistry I use because it's cheap, very long lasting and reliable.
Only films designed to be reversed gave excellent results: namely Foma R 100, Adox Scala 160 and Adox Scala 50.
Other films gave only acceptable results (all regular Fomas - which dr5.com can't reverse at all, Rollei Retro 80, Rollei Superpan 200), some gave unacceptable results (all Ilfords, Rollei Retro 100 tonal, Agfa Apx 100).

Can you tell me please, when using the Foma kit to develop film other than Foma R 100, say Adox Scala 160, do you use the same times and temps as if for Foma R 100? If not, does Foma provide target times and temps for non-Foma films, or is trial and error testing necessary to get acceptable results?

I can't make any comment on the kit as I haven't used it yet.

With films other than Foma R 100 I still use the times and temps written in the instructions that comes with the kit.
I don't change anything.
If a particular film doesn't yield satisfactorily results out of straight Foma kit I usually give up on that film.
Films are expensive these days.

This is of course the Ferrania p30 thread. It would be great to hear an independent voice on P30 reversal with dr5. Dr5 says results with P30 are spectacular - albeit at a EI of 16. Dr5 reports dmax of 6 and 10+ stops of dynamic range. Anyone with direct knowledge of dr5 and p30?

Ferrania P30 is impossible to buy in Italy. Nobody carries it.

they have a map on there site listing dealers who have received at least some stock, MANY are in Italy.

try https://www.filmferrania.com/where-to-buy and perhaps contact some of the physical shops listed in your area. This is NOT a product that you will find in Walmart.
also as other indicated the mail order folks others mentioned MAY have some product in stock. Last u date, they were still having to contract out th efinishing step ( Putting the film in cassettes) and so thay are limited to a fixed quantity of finished rolls every month. They say they are putting their effort into reviving a 120 Packaging machine.

 

[twelvetone12]

Well Alessandro is not wrong on this respect, Last winter after the new P30 was launched I did search for it in quite a few Italian shops and none had it, even ones that were listing it on stock. I did not ask Punto Foto, through.

Very interesting video here

Looks like Ferrania P30 may not be panchromatic at all! May also be native ISO more like 32. Worth a watch.

Thanks for sharing.
Yes it is very interesting.

Maybe his camera or developer has some type of issue. Density testing is closely tied to individual cameras and developer recipe/technique.

I've not experienced any ortho tendencies with P30 at 80 ASA. This chart is from P30 in Adox Silvermax developer, 80 ASA.

That's exactly what I thought !

Never trust a naked developer

I have no explanation, but he is quite thorough in all those tests so I'd be surprised if that's the reason.

I have to shoot it at EI 32 or lower to get shadow separation that I prefer. A nice nice thing about this film is that it responds well to N+ development.

Ah, I argued about it not being really panchromatic some years ago, as soon as the first P30 tests were available.

Hear, hear!

Then could we not work with the film under a red safelight if that is the case? Have you tried that?

No, i didn't say it was ORTHOchromatic. I argued that it's sensitivity wasn't similar to the otther panchromatic films, that is, that there was much less sensitivity in some colors.

Honestly, this was readily apparent when the first P30 pictures were uploaded. You can see the same with Fomapan 100: the spectral sensitivity is so different to other films, it gives an instantly recognizable 'look'.

I think that it's exciting that it's an extremely fine grained film and that DR5 loves this film under their reversal process, where it gives ISO 16.

EI 16 is pretty much what I use to obtain a decent, fully exposed negative.
Getting back to its colour sensitivity, I looked at a colour chart photographed with P30. It does look like its spectral sensitivity drops sharply off in the yellow region. In my book, this is like an orthochromatic film. It's definitely not panchromatic. I wish Ferrania would publish its spectral sensitivity chart so it would be clear. Still though, P30 a very unique emulsion. I look forward to when it's available in large format.

Yes, I sort of agree... I say it's not panchromatic. But IMO to be "orthochromatic" as we know it, it should have zero sensitivity to the red color.

I didn't understand why they say this is an ISO 80 film. But in any case I don't think a quasi-orthochromatic film can be classified under the regular ISO scale, because the sensitiviry would depend on the light source.

Orthochromatic films are sensitive out to yellow. Yellow is about 560-575nm.

 

[Mesabound]

Has anyone processed this in Rollo Pyro yet?

 

[pentaxuser]

An interesting video, Greg. I wasn't aware that ortho film was much less sensitive to yellow v panchromatic Does that mean that in say 3 portrait shots of you wearing a white, light blue and yellow tee shirt the brightness would be in that order but in fact it would be difficult to detect blue from white but yellow would be much darker?

P.S. anyone else with experience is welcome to answer

Thanks

That is my video, and the camera had no effect on film speed because the film speed was determined with a sensitometer and densitometer. The results were backed up by which bracketed (1/3 stops) negative produced the shadow value identical to the Tri-X negative. The lighting was a 5500K Profoto strobe with a soft box.

I wonder if p30 might have unusual reciprocity response - something that might yield a different speed when used with relatively short duration electronic flash.

 

[pentaxuser]

Ortho is more blue sensitive, so theoretically at least, the yellow would appear darker than the other two. In this particular video, my skin tone (which is reddish) is darker than the Tri-X, and the light blue shirt is lighter. I don’t recall from memory if the yellow patch of the color chart is different than Tri-X.

Thanks Greg. I had to go back and look at the video again in case I had remembered it wrongly but in fact the yellow in the Ferrania was a lot darker From what I recall having seen how a panchro film renders blue and yellow it look as if the Ferrania renders it almost the exact opposite

What I am not sure about is whether all ortho films do the same or whether Ferrania has a quite unique rendition of colours that does differ from the rest of the ortho films.

Allowing for the vagaries of scanning even red looks to be rendered darker on Ferrania than say Ilford Ortho but this may not be accurate as I am not talking from actual experience but just seeing other users scans
