P: Generative Remove Feedback (Lr Classic & Lr Eco)

@Dan-Fx: "With the current update to generative Ai update, selections after being replaced now have a noticeable tone change from the selected area. Making it now obvious where things were removed."

Did you apply Remove on top of an AI mask (e.g. Sky or Background)? If so, do the menu command Settings > Update AI Settings. Otherwise:

Many have observed here that the replacements made by Generative Remove sometimes don't match the photo's tone or noise. To get better matches, these techniques sometimes help:

1. Adobe recommends applying Denoise before Remove. This can reduce the noise, making it more likely the replacement will match.

2. The replacement patch supplied by Adobe Firefly has a maximum size of 2048 x 2048 pixels. If the selected area in the photo is larger than that, then the replacement patch gets upscaled (and blurry). Try removing smaller selections if possible.

3. Conversely, try making a larger selection, even including the entire background. Upscaling of the replacement sometimes won't be noticeable then.

4. Sometimes there's a distinctly visible boundary where the tone or noise don't match. You can often use the heal tool around the boundary to get better feathering and make it less noticeable -- apply Heal in small brush strokes. Or use a Brush mask with maximum feathering, dropping local Texture, Clarity, and Sharpness to their minimum values. Sometimes, making a very raggedy selection around the object makes the boundary less noticeable.

5. For grain/noise in particular, see this post for how to ameliorate the problem by adding the grain back or reducing the grain:

The white branch on the very right won't go away. Why?

@Jim 185: "LrC Generative AI has issues with blurred wire fencing (as does PS Remove distratctions) It seems to substitute another set of wires for the fencing."

Interesting, I saw the same behavior until I made the selection around the wires wider (changing the margin around the selected object is always something to try when Remove replaces rather than removes):

@gwashatka: "Every now and then when I use generative AI remove tool it will show the changed area as a different color. This is most noticeable on white walls or blue sky. The distraction I wanted to remove is gone, but the area that was edited will be a slightly different color/darkness of white/blue. This issue happens on images that don't have any masks applied."

This is a known defect of Generative Remove -- many people have complained about it here. See here for ways to ameliorate the problem:

@soichiro_8988: "The deletion function using the generative AI produced unexpected results, so we are sharing the original image as well."         

That is a little surprising:

My LR removed that flower on the left edge quickly and cleanly:

Try removing the flower before applying any masking. If that doesn't help, please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot).  And attach a screenshot showing the Remove selection you've made (as I did above).

I think you were just unlucky. I have never seen this message, so it does not seem to happen regularly.

@p.n.p: "It works only in very small areas, something that we could easily fix using the clone tool. Anything beyond that, it doesn't detect image data properly and produces random results or, basically replicates the very area you are trying to fix."

1. Uncheck Detect Objects -- it doesn't work well, especially with skinny objects and along the edges of photos.

2. See this short article for how to remove objects more reliably:

Most complaints about Remove are addressed in the article. But if it doesn't help, please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot). With nearly every one of the many dozen problem photos posted here, we've been able to show how to quickly remove the desired objects.
