The emerald sea .... arista and R09

redbandit · Mar 10, 2023

did the ol' 1:100 R09 and arista edu 400 iso in 120 format tonight... long slow process.... after 13 minutes i WAS chewing on the bath towel to stay awake.

Problem is,,, WHY did it create this massive emerald green dye cloud? Is it secretly celebratin st patricks day EARLy...

only two images worth puttin gin the enlarger though... damn 1-8 second exposures just dont work hand held.

The green color is the anti-halation dye in this film. Most of it washes out in the first bath, with little bits washing out in subsequent processing steps. It's normal.

some developers seem to remove the colour from the dye. Rodinal is not one of them.

I think he means that the washed out dye is less colorful in some developers.
I wouldn't know; all developers I've souped Fomapan in gave this brilliant green emerald color. Perhaps with some minor hue variations, but it's always pretty vibrant.

One thing I really like about Fomapan films is how easily the dye washes out btw.

never had it happen with eco pro developer... never.

Have you developed Fomapan 100 in 120 or sheet film format with it? It won't happen with 35mm.
I use instant mytol a lot, which is chemically virtually identical to eco pro developer. Vibrant greens.

I always look forward to seeing the green and miss it when developing other films.

redbandit · Mar 11, 2023

ive tried the 120 before i believe... but it went no color that i remember.

Havent had much luck developing 120 film.... Its awfully easy to get the paper mistaken for the film itself when you have limited sensation..

and it bunches up rather easy..

I've also always found 120 film the most annoying to load onto reels. It helps to cut the corners so they don't snag onto the reel, and I usually bend the leading edge counter to the rolls curve for the same reason. These two measures make all the difference for me at least. This is with plastic reels such as in Paterson and Jobo tanks.

It's definitely there in the 120: there is so much green that you can see it if you look at the undeveloped emulsion in daylight (ruining it, obviously).

That's why I use stainless reels and tanks for roll film, even with limited dexterity of one of my hands they're easy to load.

if you pull a roll of arista 35mm, it is grey on one side, and green on the other..

ive seen good and bad about the steel reels... ive even seen PHOTOS of steel reels that have some sort of tab that locks into the inserted edge of the roll film and helps guide it along..
but havent seen any for sale like that.

Nikor and a few other steel reel makers offered a guide that would help with loading the film. They're still aroubd if you look hard enough. Even the best of the stainless steel reels still rely on a clip to hold roll films in place.

As an aside, when Tri-X is developed in Rodinal, the developer is a royal purple color when drained out of the tank.
