I've read about people dissolving powder developer in propylene glycol as a means of one-shotting. The PG is supposed to prevent any oxidation from taking place, and mixing the full bag of powder means you don't need to worry about different quantities of powder ending up in the stock solution if you were to simply add powder to water in a one shot fashion. Anyway would be interesting to hear if anybody has done that with xtol. Might be handy.

To my surprise the kodak technical data sheet says that you can develop 15 rolls of film with 1 liter of stock solution with time adjustments (so 75 rolls for the 5 liter). Adox, for xt-3, is a bit more conservative with 10 rolls per liter. I wouldn't dare to try this many rolls though. My guess is that Replenishment and one shot at 1:1 are more consistent and easy to do (and as you say, that's already quite cheap)

Nice video - great idea with the wine-box. I am missing a discussion about finding good development times for the various films. Using the stock times will underdevelop somewhat with a replenished solution. When it has stabilized, bi-products will make it less active than stock and therefore more time is needed. The replenisher regime will then keep it at that activity level. Some mention that times will be somewhere between 1:1 and 1:2 times - so this is something one has to find. I try to come up with a factor and then test against same film (easy to do with sheet film) developed in stock solution to see if I am close. Unfortunately when found a working factor - it may not be the same for all films, but a good starting point.

Good video, thanks for posting. It should be noted that XTOL is a solvent-type developer, hence the finer grain, which comes at the cost of slightly lower sharpness (as compared to non-solvent types, like D-76 and ID-11). XTOL stock solution will last over a year in full glass containers. In my experience XTOL slightly lowers film ISO. For example, HP5+ should be shot at ISO 320 (1/3 stop slower than box speed) when developed with stick strength XTOL.

I am also a big Xtol fan. However, I don't use it anymore. It turns out, you can get exactly the same results with Black, White, and Green developer from Flic Film. It uses exactly the same active ingredients as Xtol, but it has been formulated into a one shot, long shelf life, syrup. No more mixing big batches of 5L at a time, no more annoying powder, no more bothering with replenishment! Great video as always sir!

This is a subject where the old adage that history forgotten is doomed to be repeated proved true. If you pulled some issues of Modern Photography or Popular Photography from 60 years ago, you'd find all of this discussion over developer replenishment versus one-shot. At that time, Kodak sold a dozen developers, and each had a specific replenishment solution sold separately. Why? Photo processing, except for DIY at home, was done in large vats of solution with film hung from racks being moved from vat to vat. The volumes of those vats were from 10 gallons on up. The solutions had to work over time and usage without change, so the developing agents were renewed with added replenishment solutions based on quantity of film developed. These solutions were chemically tested every day to make sure the compositions did not stray out of spec. Small volumes were sold so folks could do this at home. The problem of doing this at home is that most folks will not monitor the usage and do the replenishment with sufficient accuracy, so the working developer drifts out of spec and films start coming out "different". The modern usage adds another problem: There are no true replenishers, which have ingredients designed to replace what is lost during development in the main solution. Just adding more of the original developer will add developing agent, but it also adds everything else, meaning that over time, you are no longer using the original developer formula, but some other mix of components - a different developer. So long as you are happy with your on-film results, no problem. This lack of consistency won the day in the '60s, and many folks shifted to one-shot variations of their favorite developers. True, that can cost a bit more, but it's not that much more, and the simplicity of use and consistent results dominated thinking then, and it is hard to overcome today. Oh, and those wine boxes were a fad in the 70s, but died after a few years. The plastic liners are oxygen permeable, so long term storage of developer in larger volumes will kill a lot of developer and money. Amber glass bottles are the gold standard, so get some small ones and break up 5 gallons into 20 quarts. Hell, try freezing some of them if you have the freezer space. (Allow for expansion during freezing.) Video is a great discussion.

Many thanks for your detailed explanation. I like it a lot: it convinced me to switch from HC-110 to Adox XT3, as in the Netherlands it is not so easy to get Kodak XTOL anymore. So now I am re-testing the development times for my film stocks to achieve 1.3D above base+fog for Zone VIII, at box speed and pushed & pulled one stop (so, FP4+ @ EI64, EI120 & EI250; Delta 400 @ EI200, EI400 & EI800; Delta 3200 @ EI1600, EI3200 & EI6400... So quite some work). Anyhow, in contrast to 'my times with HC-110', I realised that 'my times with XT3' are quite a bit longer from the Ilford data sheets recommendations for the aforementioned films regarding XTOL. With HC-110 my dev times were always quite near the recommended time from Ilford. I am using replenished stock solution (70 ml per 135 or 120) and at 20 degrees C exactly, three gentle inversions every minute. Do you know if this is common with XTOL in general, or might be that Adox XT3 is actually quite a bit different from XTOL?

You should not pour powders like that into a funnel, it makes dust you breathe unnecessarily. You should put the cut corner of the bag either directly in or like 1/4" above the surface of the water. Also although XTOL is way less bad for the environment than D76 or similar, you should still not pour it directly down the drain, more so just for the sake of your pipes. It is best to neutralize it with a bit of vinegar, doesn't take much, to reduce how corrosive it is to the pipes before it gets diluted enough to stop mattering.

Q : everyone included Kodak, say the life span of Xtol, is around 1 year in powder, if kept dry and cool, and will last about 6 month once mixed with water, adding it may suddenly not work at all with no prior sign, from 1 day to the next. In your video lookalike, you just keep in an ordinary cabinet, yes must give to you, genius thought of the bag, but how sure you can be that it will really last that long ?

The bag just ran out for me after a year. I do a clip test on the Xtol before I use it to make sure it's still active before I use it. Also film manufacturers are very conservative about expiry times so you can get away with going over the expiry they give you.

@@psybard The machines at the factory do not magically manage to distribute chemicals evenly in every 5L batch but NOT in 1L portions, somehow. If it was that badly mixed that 1L was majorly noticeably different than another 1L, then that poor mixing also would have made 5L bags noticeably different than one another as well, on a regular basis. I used to measure out 250ml portions of D76 and it was 100% fine, never had any issues at all. Except extra dust creation, which is actually a big deal with toxic developers... but no issue with the development.

There's no reason. If you kept it the same 70ml figure for amount of developer replenished, it would by definition not last any longer than doing it this way. Meanwhile, diluted developer goes bad much faster, so having it sit around would go badly compared to stock. Dilution is inherently for one shot.

I meant to replenish a 1:1 with a 1:1. But still, it will very likely starve out of active chems and go bad, as you mentioned. Otherwise they would not warn against it in the datasheet, I reckon. Not really worh the hassle.
