Ghost Image Using Generative AI Remove

[Jeff A. Goulden]

I used the Generative AI remove tool in Lightroom Classic V14.3 to remove two people from an image.  After removing the people, there was a ghost image remaining.  I tried all 3 variations and all had the ghost images.  See before and after pictures as well as my settings.  Has anyone else experienced this?

This is a frequently asked question. You used an AI mask and the object was not included in that mask. Now that you removed the object, the mask still has a gap where the object used to be. That means the mask must be updated, shown by the red dot underneath the mask icon.

Thanks Johan.  I had the people masked.  I deleted the masks and the ghost image went away when I removed the people.

It is not generally necessary to delete and re-create masks for this; just to update them.

If they were automatically generated then you can click Update and they will be re-generated to suit the changed appearance of the photo content.

If a brushed mask was manually painted to take account of an object in the scene, and then you later 'substitute' the place where this object showed, then similarly that part of the mask can be re-brushed / erased suitably. In that case of course there is no "update" button to click, also there is no red dot to warn you that what you brushed before, may now not be appropriate to this 'substituted' photo content.

Thanks Richard, that's all good information and is useful to know.  In my case since the people in the picture were masked and I was erasing the people, it made more sense just to delete the mask.  In case you were wondering, I wanted two versions of the picture, one with people and one without people.  After editing the original I made a virtual copy and erased the people.  That's when I ran into the ghost problem.

Yes, whatever works most efficiently.

That said: re-creating an entire mask involves also re-finding the same adjustments to be applied by that.

Just updating the extent of a mask selection retains those adjustments - also, how this mask selection may interact with other mask selections - perhaps, subtracting / intersecting.

I am having this exact same problem and I cannot click on "Update Mask" as it's not highlighted.
