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!

mmh, I guess so. I cannot really understand why a gradient with matching texture seems to be an impossible task thus far. Thanks!

@Tom de Kort "I tried to remove a tree on the right side. The generative remove yields unusable results: the sky is completely off."

Many have observed here that the replacements made by Generative Remove sometimes don't match the photo's tone or noise, especially with smooth gradients like your sky. 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:

-----------------

With your screenshot, I got pretty good results with step 3, selecting most of the sky except the sun's corona (which I assume you want to preserve):

Great tips, i can work with this. Thank you, much appreciated!

Using this thread to ask a question, since there's quite a bit of knowledge:

I tried this week end using Gen remove on an image I wanted to export a HDR version as well.

If I do the remove while HDR is on, going back to SDR mode, the replaced portions are almost complete dark.

Reverse happens if I do the remove on the SDR version, switching to HDR yields pure white.

My first reflex was to kill any AI masks; none were impacted in any case by the Gen remove, and it didn't change anyway.

Am I missing something or is it not possible to do that?

[johnrellis]

@AlexJz: "If I do the remove while HDR is on, going back to SDR mode, the replaced portions are almost complete dark. Reverse happens if I do the remove on the SDR version, switching to HDR yields pure white."

I just did a quickie test and didn't observe that. In either direction, the Remove replacement remained well-blended in.  I don't recall any posts about this before, but since HDR editing isn't widely used yet, you may be the first to report a bug or limitation.  

Please upload a sample raw and screenshots showing the precise Remove select you've made and any changes you've made to Basic panel sliders. Upload the raw to Wetransfer, Dropbox, Google Drive or similar free service and post the sharing link here.

Doesn't work on underwear/swimsuit photography even if it's completely covered intimate parts. I completely understand the reasoning behind this but we use these tools to work and they shouldn't hinder but they should make our work easier...

When using the remove tool to remove a branch, it often leaves either a lighter or darker background color where the branch used to be, so it "removes the branch but leaves the shape of the branch. If you try and remove the shape again, it won't remove it.

If you applied Remove on top of an AI mask (e.g. Sky or Subject mask), do the menu command Settings > Update AI Settings to recompute the mask.  If you didn't apply Remove to an AI mask, please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot), so we can see the issue precisely.

If this hasn't yet been metioned, despite the tool working really well almost all the time, it struggles adapting to noise / grain inherent in higher ISO photos. It would be great to see the tool adapt to the grain / noise inherent in these types of photos.

[sb2314]

One of the instructions I read in the past suggested that the only setting
that should be used before using this tool is denoise. This is good advice.
I have been doing this with high ISO pics and then using Generative tools,
and it works great.

A fair number of people have complained about that.  See here for some ways to cope with it:

It has been getting progressively worse over the last week or so. Initially main problem being that once you have selected the area to remove the system then creates an area at least twice the size if not more rerquiring constant adaption. Now - well it has simply stopped working. Error message no more help that stating the obvious. Note in the selection shot the area selected is the red and white blocks area in the centre. Previously worked like a dream. Now its a nightmare.

LrC 14.2

Sonoma 14.6.1

@planeman320: "Initially main problem being that once you have selected the area to remove the system then creates an area at least twice the size if not more rerquiring constant adaption."

Uncheck Detect Objects -- it doesn't work well, especially with skinny objects and along the edges of photos.  I find it's faster overall never to use it.

"Generative Remove Failed. We've encountered an issue and can't complete your request at this time. Please try again later."

This quite unhelpful error message is shown when LR is unable to contact Adobe's servers, and it usually occurs when firewalls and anti-malware / anti-virus utilities incorrectly block some network requests from LR. Try these troubleshooting steps:

- Temporarily disable all the firewall / anti-malware on your computer. If that solves the problem, then add a specific exclusion for LR to the firewall's rules.

- Connect 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.

Thanks for responding, and I will try. However I think it worth pointing out that everything has been working perfectly up until a couple of weeks ago. What’s more I have not changed any settings, I am not doing anything different so it’s unlikely that this is the issue. Additionally I am using a desktop Mac so not quite so easy to use another network (although as I say, I am using the same network as when it was fine.)
Many thanks

[johnrellis]

It's definitely a network issue of some sort of-- that's the only time that error is issued. The anti-malware rules throughout the network are constantly updated without you doing anything. If your cell phone can do hot spotting, try that as a diagnostic. 

[planeman320]

I will but it doesnt explain all the other issues. I see somebody else has posted with exactly the same issue and timeline. I also forgot something before. On numerous occasions the remove tool leaves a ghost of what has been 'removed'.

[johnrellis]

@planeman320: "On numerous occasions the remove tool leaves a ghost of what has been 'removed'."

That typically happens when you apply Remove on top of an AI mask (Sky, Subject, Background, etc.).  Do the menu command Settings > Update AI Settings to recompute the mask. If that doesn't help, please attach a full-resolution JPEG exported from the unmodified original photo (not a screenshot) and a screenshot showing the ghost object. 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.

Hi.

I have used Generative Remove Feedback (Lr Classic) since I started my Adobe subscription 3-4 months ago, and I have been SO happy with it, as it did wonders to my photos taken in Prague, Wienna, Bratislava, Tatra Mountains etc. back in 2007. There was/is a LOT of spots on those - so many that I simply did not want to look at my photos from those 20 days travel in that area 😞

BUT LrC did it for me... until now! The last couple of weeks the Generative Remove simply do not remove the spots - and when it does, it's not as thourough as before! I have not touched the settings at all - and that goes for LrC in general.

Have there been an update that messed up this fantastic tool?

LrC Version:
LrC 14.2 - Camera RAW 17.2

The enclosed screendumps:

01. Before.jpg - the original .cr2

02. Editing_1.jpg - Marking it up, then pressed Remove

03. Editing_removed!.jpg - Removed, but it is still there!

04. After!.jpg - The 'questionmark in the sky' is still there.

The fileformat is:

.cr2 - and it is not write protected.

The camera:

Canon EOS350D (back then in 2007)

My computer setup:
My PC setup is:
Motherboard: ASUS TUF GAMING X570-PLUS (WI-FI) ATX AM4 AM
ASUS GeForce RTX 4070 DUAL EVO D6 OC - 12GB GDDR6 RAM
AMD Ryzen 9 5950X CPU
1x 3200 128GB Kingston FURY Beast KIT (4x 32GB)
WD Black SN850 NVMe SSD SSD WDS100T1XHE 1TB
WD Black SN850 NVMe SSD SSD WDS200T1XHE 2TB

I hope you can help me out on this 🙂

Kind regards

Frank

PS. I have removed spots on 1000+ photos since I started my subscription, both on .dng (my current camera is Sony a7IV), .jpg and .cr2 with no issues at all - but now... 😞

[Frank Guldber259204389t7y]

I found out 30 minutes later... I must somehow have hit the 'Capacity' ruler...! I don't know when, and have not even noticed that ruler... embarrassing (My excuse: I'm pretty new til LrC 😉 ).

So I am happy again 😉

Work in progress! It just doesn't work sometimes, and I mean that most of the time. 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.

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).

Hi.

I am experiencing this for the first time in two months (since I made my subscription). I had marked this evening for a thourough correction of a photoalbum, so it's pretty inconvinient... for me!

Is this problem something I might run into often, or have I just been unlucky today?

Kind regards

Frank

[JohanElzenga]

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

生成AIを利用した削除機能で予期しない結果が発生したため、元画像と共に共有いたします。

[johnrellis]

@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).
