I love this tool. It is fascinating how well it works and really gives images that extra pop. Currently, every time I work on one photo, my Lightroom freezes and tells me that an error occurred and it needs to close, asking what the error is and if I want to report it or not.
In the future, it would be nice if this does have the option to copy and paste to photos.

Please share your system info via Lightroom>Help>System Info...

If you encounter GPU driver issues while using ML features in LrClassic/LrD/ACR, please try to update to the latest macOS version or if you are on a Windows machine, follow https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html to update your machine to the latest GPU driver and see if the problem resolves itself.

If the OS or the driver is not available or possible and the problem persists, then try the following workaround method as a last resort. The method provides a mechanism to allow LrDesktop/LrClassic/ACR customers to force the ML inference to always run on CPU instead of default. See details here https://helpx.adobe.com/camera-raw/kb/acr-gpu-faq.html#lens-blur

So far I'm impressed. I like that I can create a shallow depth of field for an image that didn't have enough to begin with. Way easier than it used to be. At least to me it is.

If I have not posted an update, BLUR works great for me bit maybe one out of 6 or 8 tries. I can get this:

When not, my ENTIRE computer freezes and nothing works. Not even mouse. HARD reboot.

When I do get the message, LrC disables and greys out the GPU settings.

Can never tell when it will work. Sometimes purging the cache (which has near nothing in it) AND changing cache size gets it to work next try after closing and opening LrC.

Thanks for sharing your system info. Your CPU and GPU might be a little bit under-powered I think. But you have lots of RAM 32GB. Try the following workaround to force the ML inference to always run on CPU. See details here https://helpx.adobe.com/camera-raw/kb/acr-gpu-faq.html#lens-blur. It would unload some of the workload from the GPU.

Funny you should mention. I cannot get this to work.

First, the file is not downloadable. No way. When it opens, has one line- Disable GPU Inference

When placed in the directory, open LrC, GPU shows still enabled. Can you help me better try that?

On first try I fell in love with this feature, I used it on a sports shoot it worked seemlessly.

My only suggestion, if one has a bunch of like images, allow the blur to be synced accross multiple images.

My observations and feedback:

I'm running Lightroom Classic 13.0.1 on a late 2019 MacBook Pro with 32GB of RAM on macOS Sonoma 14.0. GPU is AMD Radeon Pro 5500M.

When the lens blur works, it's great. With some fine-tuning it can produce a very realistic effect. Unfortunately, soon after I started using it, it started turning the whole screen black when I'd move a slider or press Visual Depth. The same thing happened when I'd use the Dehaze slider -- black screen. When I'd use Dehaze in a mask the masked area would be solid black unless I set Dehaze to 0.

Based on comments in other threads about this problem, which started with Dehaze and seems to extend now to Lens Blur, I turned off my GPU for everything except Display. This seems to help, but now LR runs very slowly. When I move from the Library to the Develop module, for instance, the image I'm trying to work on doesn't display for several long seconds -- all I see is a grey screen. When I press the "eyeball" beside a mask, it takes a few seconds before the mask is disabled. Hard to toggle back and forth to see the effect of the mask.

So...my feedback is that it seems there's something amiss with the way Lens Blur and Dehaze are hitting the GPU. Besides disabling the GPU, I have seen no other workarounds and definitely no fixes. I certainly hope no one will suggest the solution is to buy a new computer...

I am having a lot of difficulty with the Lens Blur Tool. It is taking extremely long to function. What are the minimum requirements for its use? I have 32 GB RAM, 1 TB SSD with a GeForce 3050 GPU, and a Corei7-10700 CPU

Olhando rapido aqui sem muitos teste gostei , senti falta de uma borracha para apgar as falhas da leitura IA que as vezes deixa borrado oque não era para estar , senti falta de um controle baseado em 3d e não 2d como este parece ser , usei em imagens JPG e em RAW e os resultados foram incrivelmente bons .

Em alguns casos a seleção da IA não é perfeita, fica borrada sem nitidez por exemplo nos braços e ao redor da cabeça, então os fios de cabelo ficam desfocados , por vezes o vão de pernas , braços , ou mesmo entre uma pessoa e outro ficam desfocados ....

How do I uninstall the latest update with the lens blur? I want to revert back to my version before the update.
