Automated software to fix film processing errors
« on: February 04, 2018, 08:17:37 AM »

Someone sent me an old photo which obviously has a processing error in that the developer was uneven, is there any automated or uncomplicated way to correct the image?  see attached image

This is a local editing issue, not a global one; all the software I'm aware of that has Auto-correct features would work at the global level, so not terribly useful in this case. It wouldn't be too complicated to bring this photo into Lightroom, use the Brush tool with a feather to mask the defective area, then go first to the Temp and Tint sliders and make some adjustments that counteract the orange colour bias. If need be, you can make some further adjustments with the exposure and saturation controls. See whether this approach works - it's probably the least complicated I can think of. Similar kinds of adjustments - and a whole lot more - can be done in Photoshop, but you are looking for "uncomplicated", so this is an initial suggestion.

Everything that Mark wrote!  :)  And I will emphasize Mark's statement that there is no automated application that will fix a localized issue as shown in this example.  Mark has offered some very useful possibilities in Lightroom.  In Photoshop this would not be a terribly difficult problem to fix.  Just a matter of creating a selection of the affected area, copying it to a second layer, and with minimal work one could bring that area back very close to the rest of the image.  I won't get into the further steps required to do the job, since this procedure is anything but automated.  Also, in my experience with chemical colour processing this is not a 'developer'/processing issue.  I believe something has come in contact with the print, perhaps some time after it had been printed and processed.  Possibly some sort of liquid, not sure.  But of course all of that is moot now, since you are stuck with job of trying to fix it.  Good luck.

I agree - of course more steps involved, but along with that a wider range of applicable Adjustment Layer tools to do a refined job of it. Photoshop also provides the ability to put gradients onto Layer Masks, which could help with blending the adjustments into the surrounding photo, but here we start getting a bit more "complicated"! :-)
