Camera Raw/Lightroom: Dehaze altering the color-balance/white-balance of photos
As much as I love the Dehaze slider, there is one thing about it that I absolutely HATE and that is when it decides to go psycho in altering the color-balance/white-balance of photos.
These example photos may not show up (I've had issues with photos disappearing from being uploaded), but here is one pair from earlier today... the tint setting on WB is just 50k apart, one click on the arrow key.. but the difference is HUGE.
All settings are identical between the 2 photos, the only change was hovering the mouse over the WB tint slider and pressing the up/down key once.. changing from 5850k to 5800k
I often get similar shifts going from consecutive, continuous-high photos from frame to frame with the exact same settings, no changes in wb settings, and it all seems related to the dehaze slider and the way it analyzes the photos.
Years ago, I thought I actually had a defective camera, as the photos would change biggly even using the same exact settings 0.1sec apart. Eventually, I tracked down the cause. The programming of the Dehaze feature.
So, the problem I wish they could figure out is some way to get Dehaze to not do massive shifts in WB

IMHO, a properly functioning dehaze tool should not cause such massive color changes/shifts

I have two photos that exhibit the same behavior with just a 50k temp change with a large dehaze. It only happens at one spot on the temp slider. Notice the large change in the Histogram. If I am not on this spot than the histogram changes very little with 50k temp changes.

Knowing that would help identify which team with which to file the bug.
Additionally, would you be willing to send us the raw files with XMP data accompanying so that we can attach the me to the issue once we identify the correct team?

I shot a series of timelapse photos - each one 8 seconds in duration with a second between them. Imported them into LrC and made some adjustments. Sync'd settings across the images and noticed that some of them look wildly different in colour to the ones that followed.
Narrowed it down to just two consecutive images - one that was ultra-blue and the following one that looked more purply (I was after a more purple look so the blue one was not expected). Adjusted one setting at a time and found the Dehaze was the culprit. A Dehaze of 88 (yeah, I know - quite high) on one image made it blue and a Dehaze on the very next image (just 1 second later) was purply. Odd.
Opened each image in PS and did a Dehaze of 88 on each in Camera Raw and was very surprised to see that they BOTH looked purply. So, from my variations of settings and applications, it appears that under SOME circumstances the Dehaze under LrC performs wildly different from that in Camera Raw in PS, and Dehaze in LrC can result in wildly varying results even for two consecutive images.
Attached image shows the Camera Raw Dehazed version of image 9204, then the LrC Dehazed version of image 9204 (note how the Camera Raw Dehaze differs from the LrC Dehaze), Camera Raw Dehazed version of image 9205, then the LrC Dehazed version of image 9205 (note how the Camera Raw Dehaze is the SAME as the LrC Dehaze).

I have two photos, taken just a couple of minutes apart, and from the same location. When I add a Dehaze adjustment in the Develop Module, the images behave in wildly different ways. The only significant difference between the two images is the illuminated sign post, which was cycling through different colors as shown below. Could the color in the sign post be creating the wildly different Dehaze behaviors here?
In the first snapshot, you can see the two photos as imported, with no Basic adjustments and only the camera profile, lens corrections and a small noise reduction applied. In the second snapshot, I've added Dehaze +30 to both images. One goes strongly magenta, the other strongly blue.
Any thoughts as to why this happens? I really like the magenta sky in the second image, and was trying to replicate it in the first one. Instead, it seems I stumbled into a bug.
Notes: Windows 10, LrC 9.3, Canon EOS R raw files.
