Question

AI mask screwing up image color for some reason with the last update

Why is the AI removal in lightroom classic now screwing up the color across the entire photo when clicking remove now?  This is only just now happening after I just updated to the most recent update.

Before it worked just perfectly fine, removed and replaced things without ruining the image color.  

Now it changes the entire image.  This is unusable now and I can’t find any new option or reason it would do this.

To update…...it appears to screw up any background masks that are created.  regardless if turning them off or not before doing removal. 

This is 100% a bug, because I’ve removed things using this exact same process the last time I used this before the update and it does not bug the mask.   It for some reason is baking color into the background mask that does not exist, making it Extremely cold temperature.

I tried doing a brand new background mask after the removal, and it is getting a completely different result of the first one before it was messed up with the removal.   Almost like it needs 20x the strength on each setting to match it.

Clone stamp is doing the exact same issue.

can see here is where I started.   and then what it does after removal or clone stamp or heal brush.

    Hmmmm, so now I’m not sure how further back this issue started, because searches online point to all the way back to 14.3 or something, which I didn’t notice it throughout that, but I narrowed down a primary pusher of the temp change to the dehaze.   I’ve always used dehaze off and on, for different types of images depending the look I wanted vs using black levels, and this has never been an issue, but when not using it on the mask in this case, it brings it back to mostly normal, but still a slight color shift, but hardly noticeable, which makes me think it could have been happening for a while and not been fixed the entire time and just didn’t notice it.

    So for some reason, the AI removal is somehow changing how dehaze works and black levels too, since black levels get washed out after dehaze used.  Example, before ANY of the removal tools, AI or not, a black level of -6 to -28, requires -66+ to get a similar result after using any removal tool.  Regardless if doing remove before or after any settings being changed, completely raw or not.  Same result either way.

    This is extremely annoying when trying to maintain color consistency on images that need something removed or fixed vs others that don’t, because the black levels get messed up and the color temp gets messed up at the same time.

    Before yesterday, I’ve never, in 7 years, had to adjust any settings after using removal tools.  Was always the exact same color.

    I’ve tried disabling GPU, I’ve updated all drivers, which might be the only other thing I can think of right now causing it being a new driver messing things up….I have to test it and revert to previous.  I’ve changed back to Adobe 1998 from using ProPhoto RGB, purged cache, forced it to make a new helper and ircat or whatever those files are that store the AI information.  Tried multiple different version 15+, can’t revert back to 14 because how you guys do the catalogs.   Clicking the mostly useless yellow update mask thing that you guys added a few updates ago or so, does not do anything.  It only bakes in the bug.   Which I’m not sure what that toggle is even for, because ever since it was added, it has done absolutely nothing.  100% same result before and after clicking that to update.   Before you guys just auto update like normal and it still does the same now without even clicking that…..so it’s kinda weird it even exists, but I clicked it anyways and just like always, zero effect.   Not sure if maybe it is just supposed to bake in things to make processing easier or something?  That would make sense to me.

    I’ve tried using the removal tools, clicking reset settings and then control Z to undo to see if it would reset a color shift bug, but that didn’t work.   I don’t think that would ever work, but tried anyways.

    Don’t know what else I could try, other than it being fixed on the developer end.

    Nope, tried the older driver and removal tools are still changing how the settings work.  So I’m out of options now

    Most likely you need to update the AI mask. There should be a yellow circle in the upper right corner of the develop module right panel to tell you this. Click on it.

    Apparently something got changed when I updated to the 15.3, because reverting to the older ones still has the issue now
