T-max Developer expired... Worth trying?

[marciofs]

I know the R09 developer works as new even when long expired. But how about Tmax developer? The bottle is almost full but expired

If it has gone brown it is not worth wasting a film on. Admittedly I have never used it for many years, but the only developer I know for certain that works when it has discoloured is Rodinal as you mentioned. If you really wanted to try it do a 'clip' test, a short piece of film with a 3-4 exposures on it and see what you get. If it works -fine, if it doesn't then get rid of the bottle.

Thanks for the advise. I guess I will do the test..

I used tmax rs developer,an unopen bottle,that was 10 years out of date-it worked as new.T-max developer is different,but it is worth trying before dumping.

Let us know, please. What is the colour, haw long expired and how came out your test.

I've used it two years after opening (with all the air I could squeezed out) with no issues.

I had the exact same experience. Some discoloration does not mean it is dead, but testing is your safest bet.

I have a bottle over a year out of date that was opened nearly two years ago. Last I tried it worked fine. I'll be testing in the next couple of weeks (have a fresh bottle too) but probably not in time to help much.

I will make the test next week and I show here the results.

Just a warning. Tmax developer is not guaranteed to be dark when it's dead. I had a few bottles a few decades old (from 1980's or so). The developer was clear as new, but completely dead, as in water. Do a test run and see for yourself. If it is less than 15 years old, it's probably good as new

 

[marciofs]

It is less than 1 year old.
