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

@nathank58160098: "The detect objects feature is useless if when I trace the object, it quadruples the footprint I've highlighted onto everything around it. This is so useless now with this latest update."

@FrankMazz: "it's just awful at finding objects,"

Detect Objects hasn't changed since it was first introduced last fall. Many have observed that it fails in many situations, including skinny objects and objects near the edges of photos.  

I never use it -- it's much easier just to select the object manually.

@erica60735567: "I would love there to be a soften edge option for instances where the background is a solid color."

I agree -- 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:

That is creepy!

In this case, it looks like Remove is trying to match the shadow and reflection of the forehead on the shiny floor. When I select that as well, it does a better job in the first several variations:

Lightroom does that sometimes when your selection brush is just over the, in this case, person. Try to include more under the man, where his reflection is in the water. In general I found it works better if you select more, a larger area around the object you want to remove. 

Go to Settings -> Update AI settings

Or use 

[Option] + [Command] + U

Or click on the little yellow circular arrors at the top right 

@Rebecca217624854pcb: "I've been experiencing a sporadic error "generative remove failed". ... it could be my firewall, but I've disabled and it still persists."

If the full error message is "Generative Remove Failed. We've encountered an issue and can't complete your request at this time. Please try again later.", then try connecting to another network, preferably one serviced by a different ISP. E.g. a Wifi connection of a neighbor, a coffee shop, work, or your phone's hotspot. Sometimes the routers in these networks block LR's requests, especially in authoritarian countries like China.

If the full error message is something different, please include a full-resolution screenshot (not a phone pic) of the entire error.

@Gabriel E._Escobar L�8187: "With the last update in Lightroom Classic, Generative Remove isn't removing objects, it just replaces them with other random things with bad quality."

Generative AI Remove hasn't changed since LR 14.0.  To get it to remove rather than replace:

1. Uncheck Detect Objects before brushing a selection -- 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:
https://www.lightroomqueen.com/generative-remove-replace/

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.

@Joseph Allen-Keys: "A lot of generations aren't blending - like it needs feathering on the brush. It makes the corrections too obvious to use."
