P: Decouple Tint & Temperature Sliders in Auto Sync/Sync/Copy & Paste workflows

Probably a develop preset could be pruned down in text editor, if you just wanted to force Tint to become the same across a number of images while leaving Temp varying.

Unfortunately that is also not possible. It used to be possible when develop presets were still of the .lrtemplate type, but since they changed to .xmp that fails.

I apologise and stand corrected on this functional linking of the two parameters by AutoSync. Clearly I was misremembering.

Perhaps what I recall using to separately tweak Tint without affecting varying Temp, was Quick Develop. That method does still work - as you may know, it applies relatively not absolutely so in this case it also respects prior varying tint values. Probably a develop preset could be pruned down in text editor, if you just wanted to force Tint to become the same across a number of images while leaving Temp varying.

As always, further options exist such as Grading, Tone Curve, Calibration panel - and Masked adjustment - all allowing a common batch appearance change to be imposed without in doing so forcing any of the images' currently varying Basic panel parameters to any common value.

@richardplondon following your instructions on using Auto Sync, as I and others have attempted in the past in this forum and others, does not result in the action you have described - upon adjusting only tint, the temp of all selected images will indeed also change to the same as whichever image is previewed at the time. And vice-versa with temp/tint. Auto WB and eye dropper have not been touched. It seems they are certainly coupled in all batch operations, as the Adobe employee and other experts have confirmed. Looking forward to potentially having the ability to decouple them in a future update!

If you activate AutoSync, with several images highlighted, and then manually update just the Tint slider: this action does not touch the Temp slider on any of the images concerned.

AutoSync only concerns itself with whatever specific action you now do on the active image. Of course if that action is to click Auto for WB or use the WB eyedropper, those tools always work by reconsidering both Temp and Tint: and that must extend to other images receiving this same new edit, whichever means you use.

If you prefer using Sync (or Copy/Paste) rather than AutoSync that's entirely for you: noting, one way couples WB Temp and Tint together, the other way does not.

@richardplondon not helpful to this discussion's topic; changing the temp or tint via AutoSync also changes the other on all selected images to the previewed image as discussed - a significant hindrance with large workloads.

AutoSync can apply any edit directly onto several highlighted images. Move that one slider and you are already done.

No restrictive checkboxes, and more direct, than first editing one image then syncing this to others.

+1 for decoupling Temp and Tint sliders for batch adjustments.

I need to adjust the Tint on thousands of photos to correct Sony's slight green Tint (personal preference), but I do not want Lightroom Classic to also change the Temp to the selected photo as I have already set the Temp while shooting. It's a shame that this used to work fine on older versions of Lightroom Classic (there is another post where someone has tested multiple versions for this reason), but I love the new features and don't want to roll back. If for whatever reason this is a designed behaviour in Auto-Sync, at least give us the option to decouple Temp and Tint and have different checkboxes for each when copying the develop settings to multiple photos/creating a preset. This costs me so, so many hours of work. Thanks!

Please add a feature to allow Temperature and Tint to be synced independently of each other rather than White Balance as a whole.  They are separate sliders, so they should be able to be synced separately.

Thanks for the info Johan, I can't understand how I got those two features confused in my mind.

"My expectation for the Auto-Sync feature with multiple images selected and the Auto-Sync activated each and every edit applied to the most selected image gets applied to the other selected images. The edits are specific so if you add +10  to the exposure, if the exposure for the most selected image was +5 it would increase to +65, if the exposure of one of the other selected images was -35 it would be increased to -25."

Your expectation is incorrect. Syncing syncs absolute values, not relative changes. Auto Sync does the same. If you change the Exposure of the active image to +65, then all selected images will get an Exposure of +65, regardless of what their initial Exposure setting was. You can only make relative changes with the buttons of the Quick Develop panel.
