frans_waterlander Posted March 3, 2023 Share Posted March 3, 2023 After applying haze removal to 16-bit images, green patches appear in highlight areas, varying from just a few small ones to lots of big ones, depending on the image. The patches change in size when zooming in and out. This doesn't happen to 8-bit images. If haze removal is supposed to only work correctly on 8-bit images, then one would expect the program to gray it out. Any ideas and/or solutions?

Correction: The relative size of the patches changes when zooming in and out. Wish this forum had an edit function. Link to comment Share on other sites More sharing options...
digitaldog Posted March 3, 2023 Share Posted March 3, 2023 Try disabling GPU in the preferences If turning OFF the GPU works, it's a GPU bug, and you need to contact the manufacturer or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products. Disable third-party graphics accelerators. Third-party GPU overclocking utilities and haxies aren't supported. https://helpx.adobe.com/premiere-elements/using/gpu-acceleration.html Author “Color Management for Photographers" & "Photoshop CC Color Management" (pluralsight.com) Link to comment Share on other sites More sharing options...
frans_waterlander Posted March 3, 2023 Author Share Posted March 3, 2023 In my Photoshop Elements 2021 you turn GPU on and off in Preferences, Performance. Doesn't make any difference. I don't have third-party graphics accelerators or GPU overclocking utilities. I have Windows 10, so no haxies or other hacks. Link to comment Share on other sites More sharing options...
frans_waterlander Posted March 3, 2023 Author Share Posted March 3, 2023 Upon further experimenting, the green patches go away if you zoom in enough or save the file and then reopen it. I've also seen small, black patches after haze removal in other images, also in highlight areas. Can't think of any warning mechanisms either; Elements 2021 doesn't have a gamma warning for instance.

digitaldog Posted March 3, 2023 Share Posted March 3, 2023 It could be a corrupted display profile or a profile built using v4 (instead of V2). That the green goes away when zooming, if that is the correct description, indicates this is a display path issue somewhere (IOW, it's not in the data as you describe it). But until you upload the image to something like Dropbox so others can examine it, there isn't much more we can do.

digitaldog Posted March 4, 2023 Share Posted March 4, 2023 Zoom into the 16-bit image until you see the green issue; make screen capture. Zoom into the 8-bit image the same way; make screen capture. Save crop (or entire image) in native format, zip and upload both to something like Dropbox.

What you have shown with your images is pretty much what you would expect with having the OOG overlay turned on. Attached same image with OOG on in 16 bit and 8 bit JPEG note the lack of green in the 8 bit JPEG Frans you are not helping us to help you here when you do not supply what is asked here and in the other forum. I asked on the other forum (as did digitaldog) before knowing what your image looked like [quote]If the highlight areas are meant to appear neutral what RGB numbers do you get when you mouse over one of the areas editing in 16bit and similarly in 8 bit? Have you tried printing one of the green highlight images to see if the patches appear?[/quote]So obviously in this case highlights are not neutral however if you did mouse over the values would change showing huge move to green if this was an image data issue between 8 and 16 bit. Remaining the same could be a Display issue, profile issue etc. Similarly if you did print and no green highlights further proves not an image data issue or PSE issue Edited March 6, 2023 by TonyW Link to comment Share on other sites More sharing options...

The problem areas are all where the red channel is blown out, which is hard to avoid in this kind of sunset situation. So it looks like the haze removal action can't handle that in 16-bit but doesn't have a problem with 8-bit. Nice bug, it looks like.
