I have settled on D-76 1:1 for my B & W film developer, this works for me with Plus-X, Tri-X(400ASA), Tri-Xpro(320ASA), & HP-5. I recently started with 4X5 Tri-X and no time is given for D-76 1:1, does this mean that you should not use D-76 1:1 with 4X5 sheet film? This started me thinking about the minion amount of chemical that is needed to develop film. Kodak's estimated capacity gives the amount of film that a quart of D-76 can develop is 4ea 120 film rolls or 4ea 8X10. The smallest tank that I have is a Nikor 35mm tank with a 300ml capacity. Using Kodak's recommendation of 4 rolls/1000ml (yes I know that it is really only 946 ml), this gives me 250 ml for each roll but when it is diluted down to 1:1, it only has 150ml of D-76 developer in it. This is much less than the 250ml required by Kodak's estimated capacity but it works well. My questions are(posted 8796 days ago)1) How much D-76 is the minimum amount for a roll of 120 or 8x10 area of film.
2) Can I use D-76 1:1 for Tri-X 4X5 sheet film & what time do I give it.
3) What happens to D-76 1:1 that you can not keep the diluted solution for a time before use?
