Welcome aboard @teodoro!
Please show us images of Patagonia !

Yes, please!

thank you very much. I forgot to tell that I do a pre bath of 2:30 min with destilated water, so I think that´s not being considered in the Digital Truth table.
Don't worry; your pre-bath does not affect the development time in any meaningful way. Try the Digital Truth time linked to by @Daniela and adjust to your liking based on the results you get.

Patagonia... my dream photography place...

Welcome to Photrio, teodoro.

I forgot to tell that I do a pre bath of 2:30 min with destilated water, so I think that´s not being considered in the Digital Truth table.

A pre-wash won't affect the development time, but make sure the water is at the same temperature as the developer, or at least very close.

The Massive Dev Chart times are suggested times, some coming from the film (or developer) manufacturer, many of them submitted by users. As koraks said, use them as starting points — best to do so on a film that matters little to you, albeit correctly exposed. Check the results and later add or substract time in order to get negatives that suits you.

400 vs. 250 is a small difference, the lighting, subject and how exactly you meter plays a bigger role. I'd go with the standard developing time from Kodak as a starting point and, as others have said, adjust from there if necessary.

I checked again Digital Truth table and it´s ok. I´m following an argentine photographer called Fernando Gonzalez Casanueva and read in his wonderfull book on Zone System that TriX ISO 400 with an E.I250 is developed with D76 (1:1) in 10:15 min. (with a pre soak of 2:30 min in destilated water). The intention is aiming a compensated negative. I will do the process today and let you know my results. I guees that if Digital Truth recommends 9:45 and Gonzalez Casanueva 10:15 min for this process is not big difference

The intention is aiming a compensated negative.

If you want D-76 to be even more of a compensating developer, try at a 1:3 dilution.

I loved your photos! Can you share your process?
Thank you for the kind words.
MF photos (that you can find from the aspect ration 1:1 or 4:3) are generally Fuji Neopan400 (in my fridge since 10 years) developed in D-76 1+1 12'30" @20°C. Scanned on an Epson V700 using a Betterscanning holder. 35mm photos (aspect ration 3:2) are generally FP4+ developed in D-76 1+1 for 11' @20°C. Scanned with a Nikon LS-2000.
Not visible on your screen: when I enlarge it is on Fomabrom Variant 111 (multigrade, glossy, air-dried).

I hope that you had a look at the Norte Grande album:
It's Southern America all right, but northern Chile, not exactly the same climate as your place🙂 As concerns the process question, add: occasional use of yellow or orange filter.
Desgraciadamente, the ipernity server is suffering from long delays since a couple of months; be patient.

Did you know that Kodak recommends a minimum of 250 ml of solution? That will give you 500 ml in a 1:1 ratio for a 36-exposure roll.

Some people get away with using less, but it didn't work for me.

Hi Carlos, I´m from Comodoro Rivadavia, Chubut

A place I must return to. I have a friend I must visit.
The only film camera I brought broke and can only shoot D....
The petrified tree park is a great place for large format B&W photography.

Its cliffside beaches are also beautiful.

I am in Buenos Aires and will be traveling frequently to San Carlos de Bariloche.

The petrified tree park is certainly a place to go, I´ve been there many times. You gave me a good reason to go again!

Hi, today was the big day form me. I developed my TriX (EI 250) with D76 (1:1) with a pre sosak in distilled water for 2:30 min, agitating the first 30 seconds. Then 10:15 min in the developer with NO agitation for the first minute. Then the usual 10 seconds agitation every minute. Certainly, the result is a compensated negative! Very satisfied. Now i need to copy! The point is that I will have to wait for a few weeks since im traveling. The good news is that I´m going to Brazil to experience with Trix, FP5, Hp5, Portra! More "job". Thanks for the support

FWIW, here is the published datasheet for Tri-X film, courtesy of Kodak Alaris, the film's distributor. The data in it originated from the time when Eastman Kodak and its international subsidiaries were all part of a single whole: https://www.kodakprofessional.com/sites/default/files/wysiwyg/pro/resources/f4017_trix_320400_0.pdf

Thank you, the tech sheet indicates 9:45 min with the 1:1 dilution, very near to the 10:15 that i used. That tech sheet has very an various good data,k specially that Sunny system and filter factors! Thanks!
