I am attempting to retrieve extremely strangely colour cast photos for some friends. These are from an overseas trip and they would value their availability in something like correct colours. The photos are generally not overly marvellous photographically but represent valued memories for their owners.
While I can usually manage 'half decent' colour corrections from quite badly "colour debalanced" shots I am in this case not able to achieve the sort of results I'd like to.
While the result may well be due to "camera run amok" than bad white balance settings, as I'd first thought, I'd appreciate any suggestions re colour correction.
A look at the histograms has made me wonder if a 'correction that applies a gain step at the transition points such that the curve is continuius may fix the problem.
Notes / details:
A friend who uses a combined video/stills camera (Panasonic HC-V110) in "point & shoot" mode had a large number of photos from an overseas trip badly affected by what looks like severely incorrect colour balance setting. Only jpgs are available (as would be expected).
In many cases the histograms for all channels look very unusual with "chunks missing" and/or sudden large steps in level.
I'd be inclined to suspect camera error rather than a severe colour balance offset. However, 'playing' with settings while investigating colour balance settings returned the camera to normal operation.
