Michael,

Other than using manual repair techniques (Healing Brush, Cloning, Heal Selection) you may have few options. I took a look and there is no useful data in the color channels. In essence, the image is "blown out" for the pink/orange coloring and there's nothing there use to reconstruct what should have been there. The tools I mentioned are designed to allow you to use one part of an image on another part of an image (. The Clone tool is likely your best options. Heal Selection will use image data adjacent to the selection, which likely won't work well. The Healing Brush can use data from other parts of the image, but the algorithm won't over-right data like the Clone tool will.

You may find it to your advantage to use the Select By Color tool and replace the pink/orange with more neutral colors for the immediate background (grey for the elephant, green for the grass, etc.) before using the clone tool. You can also use selections to constrain where the Clone tool operates and masks to modify the visibility of the things you've done to the image.

Explanations, if any of these are unfamiliar to you, for Clone, Heal, Selecting, Mask are found here: https://docs.gimp.org/2.8/en/

Also, I don't think the sensor is at fault for your camera. The images do not show any type of pattern for the pink blow outs in the three images--since the sensor remains fixed no matter what image you capture, I'd expect issues to show in the same "place" on all three image. It may be the image processing software.

But, there may be another consideration--some cameras provide a setting where one taking images can see on the camera display blown highlights (my Nikon cameras do this). Does your camera provide such an option and, if so, does it also provide an option to SAVE such images (I do not know if my Nikon cameras can do this)? If it does, and you inadvertently selectws such an option, perhaps you can revert your camera to default settings? Also, if the issue is not mechanical (sensor, etc.) perhaps you can flash the camera's ROM to wipe out faulty processing software. That is another line of action beyond the scope of this reply. Too, given the costs of cameras today, it may be worth your time to simply purchase a new camera.

Wish I could offer more options.

Hi all,

Just got back from honeymoon and discovered the camera broken part way through

Here are a couple of links to some of the photos. https://goo.gl/photos/K8sVazdmNExXef2H8 https://goo.gl/photos/F2Ku8g6QuXXwDAqY8 https://goo.gl/photos/YCqCsrMwvBPUK5gC9

I think the sensor in the camera what broke as anything with a lot of white bleeds out to the pixels near by.

If anyone has any advice on how to try and repair this kind of damage I would
greatly appreciate it.

Kind Regards, Michael

My sympathies on the poor images from such an important trip.

You can change the colour of the "pink" (pink on my monitor), but I think your highlights are waaayyy blown out anyway. Perhaps a setting on your camera got changed part way through your trip without you noticing it? Try taking some sunlit photos in your backyard to see if you can replicate the effect with normal settings at ISO 200, then a much higher ISO and/or exposure compensation. The curves are strange.

You can select by colour in GIMP, try threshold 70, and change the colour of the selection by using COLORS > Color Balance. Try adjusting the "highlights" yellow and cyan sliders. It will still be ugly, but the pink has gone.

Sorry, best I can do.

Rick S.

I don't have anything to add to the good advice you've already gotten on techniques for fixing the photos. But it may not be a broken sensor. I once had a camera that mysteriously started producing images like that, even in videos (except in my case the color was green rather than magenta).

It turned out I had somehow gotten my Canon into a mode called "Color Replace" (I probably hit the wrong button while exploring menus). Once I realized what had happened, I turned off Color Replace and the camera worked fine after that.
