Re-use one-shot developers

[joho]

Doing an experiment with one shot developers like R09 with replenishment.

but have to write it out .....

Not worth it. Their practical lifespan is in the order of half an hour to a few hours. Even if you were to replenish a developer like this, you'd be shooting a moving target all the time because the degree of oxidation will vary strongly with the time and conditions of use.

Also, why try and save $0.10 on developer? Literally not worth it!

 

[joho]

you are correct !
just got the results not worth it ...

They're called "one shot" for a reason But there is nothing wrong with testing it out.

Some developers get the one shot name but don’t deserve it. Like hc110. I like to mix a tank of it in dilution c 1+19 and use it for a month then toss it. I only developer sheet film and I will never run through the capacity of it before the month is up.

With the cost of film in every size, i have no interest in reusing developer...

There is really no downside to using the developer like this. My mix is either a 1/2 gal or 1gal and I can be ready to develop without any setup. Just check temp and adjust time. I just developed 36 hp5 4x5 sheets over the span of 2 weeks in a mix of dilution c. All came out just as expected.

Edit: dip and dunk on hangers. Either Arkay 1gal ss with floating lid or a 1/2 gal yankee with floating lid.

cjb.....it all depends. My developers of choice are PMK & Pyrocat.... so different animals altogether.
