I have an image of the subject on a background that was replaced. Portions of the edges of the subject have a white fringe, particularly noticeable at 100% viewing. I cannot seem to find anything in LR v14.1.1 to remedy this. Any suggestions? Thank you kindly.
 
Can you give a bit more details about this? How was the background ‘replaced’? Lightroom Classic has no options to really replace a background, it can only change its brightness or its color. What is the subject? I have found that quite often a mask of a person is much better if you use object selection than if you use person or subject. Here’s an example of how I changed a white background into a blue background, done completely in Lightroom Classic with just object selection. No other mask refinements were made. Not perfect, perhaps, but quite good if I may say so. Having said that, really complex masks are still Photoshop territory.

Johan: This is an old Jepg. I likely replaced the background in PS years ago. Unfortunately I have no recollection of which PS tool I used. The subject is a close-up of a person similar to the one you posted. I assume that I will have to go back to PS to remove the fringing. But the question is: Which tool?
 
You can open a jpg in Photoshop and work with layers.
The problem is that you will have to create these layers first, and that is going to be the greatest challenge. You will need to select the subject very precisely, with 100% of the fringing as part of the subject. You copy that selection to a new layer, and only then you can use the well known techniques to remove fringing.
 
You can open a jpg in Photoshop and work with layers. This video shows a way to remove light-colored haloes in Photoshop: https://www.youtube.com/watch?v=kU19UXuR1vM . I've found, especially with jpgs, that too much clarity can produce haloes.
With my limited knowledge, I gave this a try & it seemed to work reasonably well. I created a separate layer for the halo removal. However, I do have a curious question. When I attempted to save the edited PS image back to LrC, it didn't appear to save. At least I could not find it. This never happened before. Must be an error on my part. Any thoughts? Thank you.

If you added layers, then the image cannot be saved again as jpg, because jpg does not support layers. It has been saved as psd or tiff, and that is unexpected for Lightroom Classic. That means you will have to import this new image. Use ‘Synchronize Folder’.

Johan: Thank you for the response. I do save the image as a tiff. If I understand you correctly, simply saving the PS-edited image as a tiff will not export back into LrC. Am I correct? Although I do not use PS often, I am not sure that I experienced this before.

Correct. If you send a jpg from Lightroom to Photoshop, then that is what Lightroom expects in return. If you return a tiff or psd, because you want to save the image with the layers, then Lightroom doesn't know what you did so you'll have to import that image yourself.

I understand. I suspect that the reason that I never encountered this issue before is because all imagesa that I sent to PS were RAW files. I will followup on your suggestion to use Synchronize Folder. Thank you.
 
In order to use Synchronize Folder, I have to know the location of the particular folder where the image is (I assume this would be on the hard drive since I am trying to import the image back into LrC). Unfortunately, I have no idea where that folder would be. However, in the process of looking through various posts on this forum, someone mentioned that if I send a jpeg to PS from a Collection, when I save the image upon exiting PS, the PS-edited image will be placed next to the original in that Collection. I tried it & it seemed to work. Thus, I assume that there would be no need to import the image into LrC since it is in a Collection already. Does this make sense?
 
If it is in a collection, then Lightroom Classic did import it after all, so no need for importing. If you want to know its folder for some reason, then select the image in the collection and choose ‘Photo - Go to Folder in library’.
