Some films esp., Foma gives green color liquid after pre-wash. I don't know what dyes they are but I wonder whether they have any effect on working stock solution in replenish scheme.
I always found better tonal range with replenished developers better shadow and highlight details, un-replenished developer give harsher results in terms of contrast..

I used several variations of D76 and in te end, settled on D76H,which I'm still mixing and using(1+1.Dear Team,
I will have to be ordering new chemistry soon, usually from Freestyle Hollywood...
I notice that they have several house brand powders at reduced cost vs Kodak and Clayton 76 which is liquid already..
Has anybody had 1st Hand experience with these alternatives?
Mostly shooting 120 fp4, hp5 and tri-x as well as some sheet film 4x5....
Maybe not having to mix at 121 degrees F?
Any sample shots, any to avoid, or do I stick with the big yellow bag?
Many Thanks for your input and suggestions...
If the formulas are identical I wouldn’t mind Saving 30%, during these strange times....
Be Safe!

OK, dumb question...
I've never used a replenished developer before...does the replenisher get added before or after development?

Well the working strength developer is in the tank developing your film, add the replenisher to the bottle you normally store the working solution in.OK, dumb question...

I've had good results with XTOL-R for a while now, although I was skeptical at first, due to my use of a rotary processor. I seem to recall that Gerald Koch who used to post here claimed there wasn't a benefit to replenishment with XTOL, so possibly a case of varied experiences?

FWIW, I'm using D-23 though not with Replenishment. D-23 couldn't be simpler to mix. Not sure I want the bother of replenishment. I've always heard folks swear by replenishment, but guess I hadn't seen the difference described as harsher contrast in the unreplenished.
The down side is, it's an extra step and an extra chemical to keep on hand (Xtol is the only one I can think of offhand that is its own replenisher, but even with that, you have your working stock solution, and a separate bottle of fresh stock for replenishment).
Thank you, all, for the tremendous help!
OK, I saw time mentioned somewhere above... Do I need to adjust development time per roll and/or sheet(s) of film processed? If yes, how do I determine how much time to add? I guess I'm thinking that a replenished solution should work the same as fresh?
Most developers intended for replenishment will have different times for stock solution (reused without replenishment, and time added for each previously processed film) or for replenished. This is because the replenished working stock reaches an equilibrium state that isn't quite exactly like fresh stock -- it gains certain things dissolved from the film, and loses others used up the development. Most replenishment systems require "seasoning" with a few films and replenishments before they reach that steady state (though there have been "starter" solutions available to speed that seasoning process).
In practice a replenished developer settles down and is seasoned quite qucckly especially if it's a small volume like 2.5 litres, it's not an issue.
Do I need to adjust development time per roll and/or sheet(s) of film processed?
+1After. That way, the developer in the storage bottle is ready to use.
May I know the sequence of chemicals that goes into M-Q Borax?
I normally give a pinch of Sodium Sulfite before dissolving Metol but how to for Hydroquionon and Borax?
Other than a pinch of sulfite before metol, I always mix in the order shown in the formula.
I noticed on Ian's web site a Kodak formula for D-76 based on the Australian MSDS. Maybe not now, but in times past, the Australian MSDS docs had more detail than those in other countries, presumably because of local regulations. I told this to Bill Troop years ago and he found it very useful. I wonder if the "Australian" D-76 formula is actually closer to the "real" Kodak D-76. (yes, I know that MSDS is not the formula but still sometimes useful)
