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

problemas en los bordes, y areas de cabello 

it would be nice to be able to add or subtract from as we can with masking.

I have just tried out the lens blur and focus tab.. after finishing I am stuck on the brush used to add blur and focus, even if i pull out of that tab and go into another.. only way out is to close down lightroom and start again. 

anyone els had this problem or is it just isolated to my computer again lol... 

I had been enthustiac about this but after trying if further I see serious problems.

1) I wish they would call the refine brushes "Refine Edge" Brush. In the dialog, until I watched Julieanne's video I didn't know what it was. Consistincy PLEASE..

2) I have a decent graphics card and yet this is terribly slow and fraught with black screens.

3) To me, this feature should be in the Masking dialog instead of the main dialog, so the subject can be selected and refined, and THEN Lens Blur could be applied using the "Intersect with" control so only the background can be selected. That's because it is much easier to select and refine the subject in Masking, where we're already familiar with using the tools. Further adjustments could then be available using brushes in the normal manner. I think being in the WRONG SECTION of LIGHTROOM is restricting its functionality.

I just tried first going to Masking and selecting the subject, then I returned to the main dialog and applied the lens blur. The Lens Blur completely obliterated my subject mask and now even in the main dialog, screens are going black. For sure this is in the wrong place! 

To make matters worse, despite Auto Masking being checked, it seems to be nowhere near as functional as the auto masking of normal brushes. It has to be refined and refined and it is SLOW and has Black Screen after Black Screen, which never happens for me using brushes in the Masking dialog.

Instead of doing this, I can flip the image to Photoshop, and use an Action I made that selects subject onto a masked layer then dups the background, makes it a smart object and applies the lens blur filter with 9 evenly spaced selection points that can each be manipulated to give the intended blur. Bokeh can be added, etc., and in under 2 minutes, I have an image with realistic depth blur NO BLACK SCREENS and no tedious corrections. and the benifit of being able to refine the subject mask, the blur in areas of the background, etc. 

I'm sure this will get better but to me it is in the wrong place and rather than working in conjunction with the excellent Masking process Adobe worked so hard to give us, it is working at cross purposes with Masking.

This needs a re-think. It's like they have 2 teams adding features, each trying to look superior ...and they don't get along with each other.

Lens blur on latest LrC. It's there but when I "Apply", comes back with "something went wrong".

The AI frequently guesses the depth wrong. Rather than try to make it perfect, it would be good to be able to paint areas to increase or decrease the 'depth' of that portion of the image. The visualize depth feature is very slow and frequently completely blacks out the window, to the point that it's not really usable. The wrong guessing of depth renders the ability to change the portion of the depth map that is to be defocused moot. I could see this working well for simple images but for complex ones with a lot of people in foreground or background it really struggles. In one particular example I have a bike race photo shot at f/4.5 which blurs the background but less than I'd like. I want to bring more emphasis to those riders who are completely in focus and are the subject of the photo. The feature doesn't do well with that at all.

Used tis funtionality for the first time and it really does well, I am a sports photographer and spent years looking to get backgrounds right and this works great to tweak. Great job well done.
