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

[Rikk Flohr: Photography]

This post applies to Lightroom Classic and the Lightroom Ecosystem products.

Camera Raw feedback can be found here.

Generative Remove makes it easier to remove unwanted objects and distractions with a simple gesture, even on complex backgrounds. For more accurate results, be sure to include the object's shadow in your selection and/or expand its size. 

Detect Objects uses AI to find the objects underneath a brushed area. The masked areas will now appear larger than the Early Access version of this feature. You can also circle objects for quicker selection now. 

We have also updated the spot selection experience to make it easier to manage variations, switch the fill type, refine the selection area, or re-generate as needed. 

Batch updating is also now supported for Generative Remove spots. 

Try out the latest updates and share your feedback with us here. Please also include the following details in your post: 

• App version
• System details
• Example image(s) if you wish to share

Our team continually monitors this thread to track issues for future improvement. Thanks!

@Colin332508902nkk, with the boat, it very much looks like you've applied an AI mask to the water to darken it, and that mask didn't include the boat itself:

Do the menu command Settings > Update AI Mask to recompute the mask after removing the boat, and you should get a very good replacement:

A similar issue appears to apply to the kite -- it looks like you've used a Sky mask to lighten the sky, and the mask didn't include the kite. Again, do the command Settings > Update AI Settings to recompute the mask.  You should get a much closer (but still somewhat noticeable) replacement with a distinct boundary:

Many have complained here about such mismatches in tone and texture. In this case, you can use the healing brush with many short strokes on the boundary to feather it, making it much less obtrusive:

Other techniques for these mismatches 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 using smaller selections if possible.

3. Make a larger selection, even including the entire background. Upscaling of the replacement sometimes won't be noticeble 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. 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:

@Colin332508902nkk: Now that you know the issue with Remove and AI masking, are you still seeing a big difference between LR Desktop and LR Classic? If so, please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot), along with screenshots describing the problem edits, so we and Adobe can see the issue in detail.

Seriously the number of times I'm randomly told "We encountered an error please review our guidelines" with 1) No actual explination what it is talking is both extremely unhelpful and extrmemely aggrivating and 2) given my best guess in most cases quite literally inaccurate. I get that it's looking at the whole image to try to generate the best matching content I'm wanting but it's detecting for example too much skin and instead of erasing the flyaway hairs I've selected to erase it's like assuming I'm trying to erase clothing or some nonsense instead of seeing I'm trying to erase a dude in the background. 

1) Actually add what the system thinks I'm doing that's against the "guidelines" as that's just plain useful info and not including it is plain stupid. Yes, stupid. Serves no one to not give a proper error message it's 2025 not 1993.

2) Please adjust how it determines this as it's throwing false negatives like crazy. 

[johnrellis]

@August_The_Dragonfly:  "We encountered an error please review our guidelines"

There are a fair number of similar complaints in this thread about Remove mistakenly thinking a photo violates Adobe Firefly guidelines. You can read the "guidelines" (i.e. rules) here:

https://www.adobe.com/legal/licenses-terms/adobe-gen-ai-user-guidelines.html

So far, however, no one has posted sample images that were wrongly flagged.

In both LR and PS Beta, I have tried to remove one person from a group photo, but generative ai persistently tries to fill the space with another person.  All I want to do is remove the person and fill the space with the background.  I have tried everything including tighten the selection, expand the selection to include part of the background, but no matter what I do, PS and LR ai puts another figure in place of the one I am trying to remove.  What am I doing wrong?  Also, I dragged the photo into your box below, and it said it was too big - come on, as a professional photographer, I deal only in large raw files and I would expect Adobe to accommodate!

[August_The_Dragonfly]

I've had luck using the heal brush and cloning basic background elements over the person first (like a really bad paint over) and then using the generative AI with no prompt in segments to clean up edges and such.

[johnrellis]

@tomb2763: "I have tried to remove one person from a group photo, but generative ai persistently tries to fill the space with another person"

Make sure to remove any shadows or reflections from the person and any disconnected parts (e.g. an arm over the shoulder of another person).  Removing the disconnected parts can be a little tricky due to a LR design bug -- see here for a detailed example of removing a person from a group photo with three disconnected parts:

If none of this helps, please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot). With nearly every one of the several dozen problem photos posted here, we've been able to show how to quickly remove the desired objects.

The generative Remove has been working very well. Starting today 1/13/2025 it removes tiny objects fine but anything bigger than a "stanp" size is smudged badly.

@SiamackSF: "but anything bigger than a "[stamp]" size is smudged badly."

There are several easy-to-resolve possible causes. Please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot). Also attach a full-resolution screenshot (not a phone pic) of the entire LR window showing the Remove selection and smudged results.

Hi!

No idea if this hint has already happened: Perhaps it would be useful if you could provide comparison photos, e.g. from the web, to the AI. I have already had the case several times that I wanted to remove a poster or something similar from the picture. The solutions generated were often not so good and in most cases images already exist in the web, from time points at which the disturbing element was not yet there.

[john_2203]

AI has been working perfect up to this point. Some great improvements have happen most recently. Thanks! 

[Mathias23592962evfe]

Comlete nonsense!

There is nothing removed. The marked object is replaced by some other object. Pure phantasy!

[johnrellis]

@Mathias23592962evfe: "The marked object is replaced by some other object."

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.

Remover objetos por IA deveria de fato remover objetos. Eu recebo muito resultado ruim, incluindo objetos que não deveriam estar ali. Se o objetivo é remover, não deveria incluir. Removendo libros de uma prateleira recebi imagem colocando LIXO, uma lata de lixo e uma torre de papel amassado no lugar. No Photoshop funciona melhor quando eu consigo descrever com prompt simples: "remove with content aware". É mágico! Só que no LR é uma tristeza. São muitas tentativas. Tantas que me questiono se essa é uma ferramenta útil no LightRoom, porque só me fez perder MUITO tempo de trabalho. Triste e frustrante.

[johnrellis]

@Leandro_Barreto: "I question whether this is a useful tool in LightRoom, because it only made me waste A LOT of work time."

There are many dozens of examples posted in this thread showing it usually works quite well. But as with any AI tool, there are certainly some instances where it doesn't. Please attach a full-resolution JPEG exported from a problem unmodified original photo (not a screenshot) and call out what you're trying to remove.

I'm attempting to replace an electrical box on a wall that intrudes into the rectangle for the graffitee that is the subject of the image. What I get with generative AI is new material with people and objects that aren't in ant of the photos in my library. I also get partial replacements and replacement with other objects in the image. Since the box is surrounded by a stucco wall, I would have expected that it would use this adjacent area to remove the object. In no iteration was the replacement anywhere close to replacng the box with anything closely resembling the surrounding wall. Totally useless for this photo in any case.

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, but there's no guarantee obviously with your photo.

Hello.



This is the original photo.







I wanted to remove the person in the foreground, but I got this:







I made several attempts. Once there was a road construction worker, once a
child bending down, and finally this very object. What happened there?



Best regards

@Mathias23592962evfe, the photos didn't actually get inserted into your reply. If you inserted them into your email, that won't work -- you have to do it by coming back to the web in your browser to reply.  Regardless, perhaps just attach them rather than insert them into your reply in the browser. Thanks.

[Mathias23592962evfe]

Hello,



this is the second attempt to send the picture before and after removing the
person in front.



Best regards

M. Dietrich

Hmm, they're missing from your second reply too. I checked both Firefox and Chrome, and they're not in the HTML :-< When you go back to the replies in your web browser, do you see them?

my ai erase not working please start this other wise i stop your cloud payment

[Hal35668775dy1a]

This does not work as well as photoshop? why?

[johnrellis]

@Hal35668775dy1a: "This does not work as well as photoshop? why?"  Generative Remove in LR uses the same algorithm as in Photoshop. Try unchecking Detect Objects (on by default in LR 14) -- it doesn't always work well, especially with skinny objects and along the edges of photos. 

If that doesn't help, please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot) and call out what's not working in LR but works in PS. 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.

just made a mess of the attached photo.   LR classic.
