OK, so i assume then that Kodak only considered the need for rem-jet by the time they were introducing colour films?If you read the data sheets for the currently available movie films for Black and white they tend to have an antistatic /lubrication layer on the back. But that is clear as B&W processes (as explained in Module 15 of the kodak manuals) don't have the spray arms and such that REM-JET would require. " BASE EASTMAN DOUBLE-X Negative Film has a gray acetate safety base. The backside of the base contains an anti-static layer with lubricant. " and "The N 74 plus is a marked advance over its predecessor, thanks to improved slippage,extremely low shedding and excellent antistatic qualities. {antistatic back layer}
"
The big coater ("big boy") was so huge, soooo huge (i guess Over 9000 square meters), that you would think that the head of the coater at the LRF should be designed in such a way to be identical to the one in the Big Boy, but with a far smaller width. I mean, the LRF coaters must have been built (1965?) with an intentional similarity to the Big Boy coater, in a way that an emulsion tested in the LRF is easy to be 'translated' to the Big Boy.
I mean, if an emulsion is tested to work great in the LRF, and then it can't be translated "as-is", or with predictable tweaks to the Big Boy, then the costs of final testing in Big Boy itself would be huge.
I will wait for Photo Engineer to enlighten us on this topic.
Thats sweet, so now that its clarified that rem-jet is no issue for motion picture use, I expect itMy bad on the rem jet. I was extrapolating from Nicola telling me that P30 ALPHA 35mm is "not ready for cinema usage".
I'm prone to extrapolation from minimal input, and in the heat of a live video stream, I obviously said a few things that are not technically correct, even if they are correct "in spirit"...
Scotch chrome wasn't paticularly good, the dyes fade with time. David, can you tell us if the new film will have a better formulation with more stable dyes than the older one?
I did point out that D96 is much better. Marco has been insisting that it is THE chemistry that should be used to process P30. But that's because he can buy it with no problem through his cinema lab in Florence.
C41 is off the map at the moment and there was no talk about it. Solaris was the last Film Ferrania made (in the large coater) but perhaps the Scotchrome was the last that the LRF made, thus the formulation -> production differs. This was briefly talked about, how they have a book of products that were made in LRF.
I think the main reason that Scotchchrome was chosen was because there are already tons of negative C41 films on the market, but at the time Film Ferrania got started, Kodak had recently stopped production of Ektachrome and an E6 film was the logical choice, even with the return of Ektachrome, E6 film has the biggest gap in the market.
I think that it was sort of the other way around.OK, so i assume then that Kodak only considered the need for rem-jet by the time they were introducing colour films?
I guess that the motion picture labs would not have wanted the hassle of upgrading the machines for remjet removal, so Kodak never added it to B&W film?

This is the first time I've seen anyone mention that Scotchchrome dyes fade... But it's somewhat irrelevant at this point. We are not making Scotchchrome. This was only possible during our narrow 2015 window. We are creating a new formula using Scotchchrome as a "basis of comparison" and to compress some of the R&D.
Thanks Ron for the answer regarding scaling between 'research' and 'production' coater.If there is a difference between coating machines, you can develop a scaling method to predict the changes needed to move products around. Most all of the time it works. One notable failure at EK was Kodachrome 25, where the initial transition did not work, but it was terminated before a final formula could be reached. There was not enough money to continue the work.

I feel this means that the film decline has halted and there is some resurgence, much like vinyl...
D76 is way different than D96
the formulas are related but slightly different:
INgredient D76 D96
Metol (Elon) 2g 1.5g
Sodium Sufite 100g 75g
Hydroquinone 5g 1.5g
Pot bromide 0g 0.4g
borax 2g 4.5g
It's really funny that you say this because despite the volumes and volumes of text we have published on our site, the vast majority of people simply do not read. We know this because we are continually asked questions that we have already answered, often many times.
Will the Ferrania P30 come in DX-coded cartridges? That would make it easier to shoot in my Pentax P30T.
Seconding this, for my Yashica T4. I'd have asked myself but I was out buying a projector!
Well, I don't plan on a trip to Italy. I don't speak Italian! So, there it is.
I'll be happy to be your personal interpreter if you come to visit Italy and the Ferrania plant.I don't plan on a trip to Italy. I don't speak Italian! So, there it is.

ahahahah!Just make sure your words are always supported by energetic, evident hand gesticulation, and you will be understood. The more exaggerated, the better.
As for lab work in Ferrania, you can get by the following phrases:
English ---------- polite Italian
This does not interest me, please let me work alone ------------ Vaffanculo!!
This emulsion does not satisfy my own standards ------------- questa emulsione mi fa cagare
I think you are not doing the correct thing, let me see... ------------ che cazzo stai faccendo!?
Our schedule is tight, we'll not gonna make the slide film if you don't hurry, come on! ------- dai cazzo!!
With friends like you guys, I don't need enemies.
Tsk, tsk.
