# Thread: Developing time for Tri-X film

and what about times for stop and fix?

Thanks for all the replies! I really want to get back into film

Yes. Mix up the gallon of D76. Call that your stock solution. Just before developing, figure out how much solution you need to cover your film. Let's say you need sixteen ounces of solution to cover your film: take 8 ounces of stock solution and 8 ounces of plain water to make up you working solution. Try to have your working solution 68 F. Use your working solution once and throw it away.

Stop bath--thirty seconds to a minute shall do just fine; use constant agitation.

Fixer: with fresh fixer, pour it in and agitate gently for about a minute. Then you can take the lid off if you desire. Fix for 3-5 minutes, depending; agitate in the fixer every thirty seconds or so.

Read the link to film developing provided above. Good luck, have fun; and keep asking questions. We're here to help.

2. anscojohn,

thanks for that info, that was exacly the answer i was looking for.

3. I shoot lots of TriX at an exposure index of 200-320 depending on the light, and develop in D76 1+1 at 20C for about 8-9 minutes, depending on the light.

4. Tri-X in D-76, exposure index 250, 8 minutes in D-76 1:1 at 68 degrees F. Agitate continuously first 30 seconds, then two inversions of the tank each 30 seconds thereafter.

Tri-X in HC-110 dilution B: EI 250, 5 minutes at 68 degrees F. Agitate continuously first 30 seconds, two GENTLE inversions each 30 seconds thereafter.

5. Last September, I wrote the results I had with TX400 / HC110. Here you can read it:

I just want to add that I repeated these analysis two months ago, and I got the same results. This time; I also read the relative density in Zone VIII, and it was 1.25.
Theoretically, if you work with a condenser enlarger, like my case, a good exposed and developed film should has the following relative densities: ZI: 0.08 - 0.11 / ZV: 0.60 - 0.70 / ZVIII: 1.15 - 1.25.
I think TX400, EI200, HC110, 1:47 (E), 6 minutes, 20ºC is OK.
