When I want to soften a bokeh, I can create mask by clicking the "Select Subject" button, invert it and decrease Sharpeness.

 

But the problem occurs at the edges of subject, the edges of subject are blurred too. The only way is to create another brush mask, paint around the subject and subtract it from original mask.

 

1. It would be nice if there was a feather control in "Select Subject" that would extend the mask.

 

2. It would be great if there were an option to automatically recalculate AI mask after synchronization or if mask was copied to a new photo or when applying preset with AI mask.

 

With this features softening the bokeh could be saved as a preset and it would be very easy to apply it.

I think this would be really useful. Especially in luminance masks it could prevent detail loss because of tone compression, which otherwise happens now and then and looks really ugly.

How is that different from using the upper and/or lower falloff in the Luminance mask, and the Refine slider in the Color Range mask?

The falloff is still based on the luminosity value. An additional feather option would create a soft edge regardless of the color/luminosity value and would help to preserve details in areas with little color variance (where tone compression can become an issue).

If you post detailed screenshots of an example photo illustrating what you want, you might get others to upvote this idea, and Adobe will be a little more likely to consider it.

Here it is. To demonstrate what I mean, I created a luminance mask with Photoshop (Color Range Selection Tool on the highlights), as Photoshop has a feather slider in the mask properties. You can encounter the same issue (second paragraph in the picture) in Lightroom, but there is no feather slider to get rid of it.Luminosity_Feather_Example.jpg

Here is a screenshot directly from Lightroom. It shows what happens when you apply a luminance mask to the brighter half of the picture (with falloff stretching to the shadows) and reduce its brightness by 1 stop.

Here is another example how mask feather (aka "edge softening") can help to recover lost details and improve local contrast dramatically when working with Luminance/Color Range Masks. IMHO that's an important feature and I don't see any way to do this in LR right now. Or am I missing something?

Using an inverted "Select subject" mask and sharpness adjustment can create great depth focus. Unfortunately the edging of a subject are caught up in the subject mask and a fully edge.

 

Please add the ability to expand a subject mask by a set number of pixels to prevent this phenomenon.

The more I work with luminosity masks in LR, the more annoying this issue becomes. Please, Adobe, add a feather slider. It's a simple fix and it would make luminosity/color range masks so much more usable.

(Expand/Shrink (by a certain number of pixels) would be a nice addition, too.)

Hi! Some of these features are sorely lacking and forces me to export the image to be finished in another app:

 

- Sky and object mask: the lack of refinement and diffusion option around the selected object is lacking. For example, inverting the mask to manipulate the background, often the object becomes useless when the mask invades part of the object's edges. This feature would be very useful.
- PNG export: depending on the type of photo it is inevitably necessary to export it to another app and repeated manipulation of JPEG images is destructive and no other mobile app supports TIFF
- Liquify brush: useful for many corrections and also avoid the need to use another app (Polarr, for example)
- Masking with the same features as the unmasked image: selective hue/saturation/brightness manipulation, add noise, detail,... Very very useful.

 

Thank you!

It would be nice to be able to use the select subject option in Lightroom, then expand the autoselected mask a few pixels out to readjust the selection. 

 

Personally, I do a lot of corporate headshots and the like againsts a blown out white wall. I usually select and mask the subject and invert the selection to ensure the wall is completely blown out edge to edge. This works great, but a lot of the time when I do this the subjects hair gets all crispy. I usually fix this with a wacom tablet and pen, but it would be nice to have a more macro-level technique to emplement.
