How do I solve this ID-11 mixing problem? : LUSENET : B&W Photo - Film & Processing : One Thread

I've mixed all kinds of developers over the years, including ID-11. This time, despite my best intentions, I mixed part B first, in 3/4 of a gallon of water, and then added part A, yadda, yadda, yadda, and water to make a gallon. Of course, this is the reverse of the proper order. I'm so ashamed. Now, do I dump my reverse-mixed gallon of ID-11, shoot a test roll and see what happens, or continue developing my film as I always do? Any suggestions are greatly appreciated.

If everything is gone into solution it should be fine. But a short clip test won't hurt.

Luckily, with D76 this doesn't matter too much. The packet order is to help with dissolving the chemicals, and has very little bearing on the final mix.
With colour chemicals, and other more readily oxidised developers, it's a different matter, and you might end up with an insoluble sediment, or a partially oxidised solution.

Sorry! I just realised I might have confused you by mentioning D76. ID-11 and D76 are the same formulation.

The main purpose of having two parts for ID-11 is for ease of mixing, so if you got it to dissolve, then you should have proper working developer.

There is one minor issue, though. Some of the preservatives are in the Part A, so the Part B might have started to oxidize a little faster than normal before the Part A was added. So while the developer should work fine, you may have a shortened shelf life of the solution.

Thanks to you all. I'll shoot a test and hope for the best.
