It would be great to have access to the side by sides for all of the different films on a website so that we could compare say the Arista 200 to the FP4 side by side. Loving the seires though.
Even a shared Google Drive folder would already be enough so we can download the images and compare them by hand. Almost no effort required and it can be added to on the fly when new episodes are released. This would be very helpful.
I would love to see the impact using Rodinal, HC110, XTOL, D76 and DDX have on the spectral response compared. I usually use Rodinal with Foma films as although the highlights can be challenging I like to compensate for the 'milkiness' (?) which I feel Rodinal helps with. Foma 200 is apparently t grain? I would also love to see the graph for multiple batches, I was wondering how much variability there is. Thanks for the video!
With all of these videos comparing to tri-x, are there any favorites you come across? Or even just some that seem to be a cut above on pleasing grain, good dynamic range, etc
It's strange. You told us that Fomapan 400 is slower than 400, but you're telling here that arista is a 400 speed film. They are the same film as far as I know. They both have increased red sensitivity and decreased Cyan sensitivity
Potentially. The speed was determined by exposure on my sensitometer and plotting, then finding the speed point of 0.1 above base fog. I also compared the visual density of the negative (I bracketed my shots) to the Tri-X negative. I can’t explain the differences, I just report my findings.
@@TheNakedPhotographermaybe is due different batches. Foma Bohemia is not the most reliable source of precision. It can have something to do with how old was either the films. Many variables. Either way, I like foma 400. It haves a beautiful spectral response, and for large format is fast enough for a fair price.
the key here is 'as far as you know'. And you don't know much, apart from urban myths propagated on internet forums. Nobody knows what Arista 400 *exactly* is. Could be it was Foma 400 at some point, then no more. Could be it still is, but it's old stock Foma 400, or B-stock Foma 400. Perhaps there's huge batch variability at play and the speed differential is due to batch variability. I'd just bypass the issue and shoot whatever you like the most.
It's interesting that your results showed this was a true 400 speed film. In my (non-scientific) experience, Arista EDU is a bit slower than what it says on the box - or have I been under developing this entire time? (stock XTOL 7min)
It's a true 400 speed film? Well this is good news. We can't expect this film to be as good as Tri-X, but if it's gonna be less than half the price, I'm cool with it. I just wonder who makes it. Is it Foma?
@@jimmyha5212It's an unproven claim that Arista = Foma. Our guy here got rather differing results from testing either. But we can't know for sure why that is. Someone could ask Arista, but I doubt they will get an answer. Still, everything else is speculation.
Arista = Foma. Period. The only film producer in Czech republic is Foma Bohemia. We often get medium format rolls with font and tape used on Arista export films (it is different than Foma font and tape) in our lab but packed in Fomapan boxes. This probably happens when they produce more than needed in out of EU markets. Tape used on Arista MF rolls are different than on Foma rolls. Tape on export rolls are very sticky and cannot be taken off. Tape on Foma rolls are standard masking paper tape, that is easy to take off. There is no doubt Arista is made by Foma Bohemia in Hradec Kralove. Same as Lomo Earl Grey and Lady Grey and other third party rebranded films. Last but not least, when you develop Foma made MF rolls packed in whatever boxes, your developer will be dark greenish/blueish. This doesn't happen with Ilford/Harman made films or Kodak made films.

truly my favorite channel - thanks for all the work 🧀

Just.... thank you for all free and very good content you give us!

Its Very easy to read the numbers through the little red window.

My vote also goes to Arista 200. I bulk load it to bring the cost down even further.

Yes, i wondered the same on the Arisa 200, as thats Fomapan 200. He got 200 iso from that but not from Fomapan 200.
Devlopment time may give different results.

It is slower, it's literally Fomapan 400, that means it's true speed is around 250.

Its fomapan 400
Yep, it’s Foma!
@@Nobody-Nowherethat's where I get confused. Nobody says Foma is true 400 speed film.
