P: New AI-powered Lens Blur (Early Access) available across all surfaces.

This post applies to Camera Raw, Lightroom Classic & the Lightroom Ecosystem products.

The Lightroom team is sharing an early look for AI-powered Lens Blur–giving you the ability to apply optical blur on any image regardless of how it was taken. Lens Blur is now available to try on all Lightroom surfaces.
 
How does Lens Blur work?
  • Lens blur applies a depth-based blur effect, similar to what can be achieved with real-world optical lenses, by using AI-generated or device-captured depth data (when available).
  • Lens blur will automatically prioritize focus for the detected subject, but you can also interactively adjust the focus distance. Precise focus range tuning is also available (currently desktop only: Lightroom Desktop, Lightroom Classic, and Camera Raw).
  • You can also further customize the Bokeh shapes, highlight Boost (desktop only), and make depth map refinements (desktop only).
 
Will my Lens Blur adjustments on one surface be synced to other surfaces? I.e. mobile to web to desktop, and vice versa?
  • Yes, all edits will sync. To revert settings, you can go back to previous versions or history steps, or un-apply Lens Blur settings.
 
Can I add Lens Blur settings to my presets?
  • No, presets and copy + paste workflows are not currently enabled for Lens Blur during Early Access.
 
For more information, please check out Lens Blur. 
 
Please give it a try and share feedback in this thread as we continually improve this feature.

When the background blur misses a bit how can I make adjustments?

I notice that LENS BLUR analyzes the entire image, even if I crop the image. Will LENS BLUR tool ever allow one to analyze an image after it has been cropped? Then it might work better on the cropped image.

It works like magic! I wonder how it' s possible, to create such an accurate depth-map of a shot taken, without any real depth information. Thanks for this awesome feature - with all its pros and cons to photography...

Great feature, would like to see a feather feature for the edge so it wouldn't appear so hard and sharp

Thinking of real world behavior, how would that be useful?  If something is in focus in the foreground, blur from objects in the background doesn't bleed into the foreground object...

Thinking more on this, I can think of a situation where it would be useful:  Consider an object that is in the foreground, but curves from front to back - maybe a closeup on a large object like a car.  In that case, the blurring would be gradational.  It would be interesting to see how the tool handles that.

Needs to be able to work with user created masks too. AI is not exactly a genius at reading our minds (not yet)

Very useful even in its early access form.

Suggestions:

  • make the generated depth map a mask entered into Masks panel

Observations:

  • intermittently required a large amount of memory. LR physical memory usage climbed to over 20GB. 
  • Intermittently caused large, continual usage of GPU, even after the initial effect was produced, without any additional control inputs. 
  • Intermittently appeared to cause significant LR slowdown (often correlated with observing continual high GPU usage).
  • Depth map had difficulty following extended open objects in the same plane. For example a wire fence (open wire squares) in the same focal plane, was only selected around the main subject.

From what I've done with it so far, it works GREAT! Very easy to use and very good at deparating foreground and background subject! Yeah, it's GREAT! Mitch

the blur itself is surprisingly good but since everything hinges completely on the mask is unusable for high end commercial retouch as it stands. The masking is all over the place. for now, a little more than a gimmick.
