Develop, stop, fix, oops stop again...

[Ian Leake]

I'm just washing an 11x14 neg which I developed using a drum, but I managed to pour in the acid stop bath again after fixing. My guess is I've done no lasting damage, but can anyone confirm this for me? Once I realised my mistake I washed with water briefly, re-fixed for a minute and then washed normally. Was this OK? And if not what should I have done and what can I do now?

Many thanks in advance.

Ian.

Ian, you should be fine. I actually do use a weak stop bath after fixing my negs to get rid of some residue I've had problems with the last several months. If you do a search for "residue on film" you can read the suggestions that led me to try that method.

You're a star Cheryl. Thanks

Reminds me of the time I tray developed some 4x5 film, got "lost" in my 5x10 foot darkroom (no small feat, let me assure you!), and shuffled the film around in the stop bath tray for 4 or 5 minutes before putting my hand in the tray to the left of what I thought was the developer....I cussed some, rinsed the negs in water, put 'em through the trays in the right order, and turned on the lights, to no ill effects. So now I claim credit for discovering the Stop Bath Development method.

You must have rinsed yours much better than I did the one sheet if 8x10 I did this with. Mine is unprintable.

I've done the same thing a couple of times when developing color paper. (I do this in open trays, which I find much faster and easier than using drums.) I rinsed the paper at the sink (by feel, of course) and proceeded with normal development. The results seemed OK, but of course this was the final full-size enlargement, so if there were small defects I might not have noticed, whereas if a negative were so treated and then needed to be enlarged, it might be more of an issue.

some weeks ago i put the stop-bath before the developer into the drum and waited 12 minutes (for developing :confused: ). but i realised that. 10 minutes of washing the film in the tube, and then i used the right order.
everything was ok. no marks, nothing. very nice negs.

but i think tj´his was more luck then anything else.

Why use acid stop bath ??? I use plain wather.. two times.....
And develop in APH09 for 60 min.... somebody call it standing development......
But it works......

I once turned the light on when the film still was in the stop bath. No problem, the negatives came out fine after the fix. I'm not sure it would have worked if I used plain water.

You must have been extraordinarily fortunate, or really, really fast. My understanding of the process is that film and paper is still light sensitive until the fixer has removed all of the silver that had not been affected by the image forming light, and would otherwise fog.

I will fog, but slowly. Since it doesn't develop in the stop bath, all the fog you get is the "printing-out-fog" which is very little in normal indoor lighting. If you then use an acidic rapid fix even that little hint of fog will disappear.
