Camera Raw/Lightroom: Dehaze altering the color-balance/white-balance of photos

I've logged an issue with the Camera Raw team and attached your files, Doug. You can pull them offline if you like. 

Here are a couple of more examples... these are what I was describing using the same exact settings between 2 frames captured 0.1 seconds apart, but the dehaze tool causing them to look very different in color.

and of course, it happens in the dry also.. this example isn't as big a swing because dehaze is fairly low (25).. with a higher dehaze setting, the color shift would be more significant.

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

To counter the effects of color shift, you can use the dehaze slider in photoshop camera raw filter , on a duplicate layer set to luminosity blend mode.

Seems like a bug

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.

In your first example Doug, if you take those two files into Camera Raw and apply identical settings, does Camera Raw exhibit the same color difference as Lightroom? 

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?

This reply was created from a merged topic originally titled Dehaze in LrC performing wildly different to Dehaze in Camera Raw.

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).

egos and narcissism........zzzzzzzzzzz

I noticed a similar problem to Mark Robinson above:

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.

In experimenting a little more, setting Dehaze to -100 makes one image have a strong greenish cast, and pushing to +1-- gives it a strong magenta cast.  The other image, -11 gives a strong pink/orange cast, while pushing to +100 gives a strong cyan cast. Other images from the very same shoot don't behave this way.
