is it possible to redevelop film?

[wilfbiffherb]

I have just processed some film in a jobo rotary and there are streaky areas of blue in my skies which look like uneven ddeveloping. I know you can rebleach and fix but is it possible to redevelop to try and get rid of thesee streeaks??

I'm afraid it's too late to redevelop. Unlike b/w film, color does not retain any silver after bleach and fix is done. Once silver is gone, there is not much you can do.

No. Once you fixed the image, the undeveloped but exposed silverhalides that you needed to develop in the first go, are gone, meaning you can not "correct" a developing error like streaks caused by bad rotation.

You can bleach a B&W film image and redevelop it, but it will come back with the same streaks and uneveness of the original.

100% correct, once the silvers gone no.

There is a techniquee called looping which was used by astronomers where a colour film was developed and fixed, then washed and bleached in a rehalogenating bleach and redeveloped this built up the dyes and could be repeated a few times before finally bleching and fixing.

Yep Ian you are correct, some call it rehal or acceleration too. I have played with it a bit with interesting results, but re the OP, like you say, is out of luck unfortunately

This is a colour film so all the silvers been removed if the bleach and fix went to completion. As the swirly bits are printing or scanning lighter from a negative it sounds unlikely the excess density was a developer isue but it could be incomplete bleach/fix or the bleach wasn't poured in fast enough and/or an agitation problem.

As has been stated here not all is necessarily lost in your case. Have you tried rebleach&fix yet?
