P:(Masking)Add controls to modify mask to expand, contract, or feather in AI Selections

Here is an example of what I'm talking about (sorry for blown highlights - just pulling something up quickly)

The first is the original bokeh (looks kind of crunchy to me from harsh lighting):

The second is with a background mask applied and clarity pulled all the way down. You can see the bokeh looks nicer now, but the edges of her hat are all fuzzy.

The third is what I was going for – I hand-brushed away from the background mask so that the edges of her hat weren't affected. Now the bokeh looks creamier and she still appears in focus (ish - but that's my fault). This could be more easily accomplished with an expand and feather function for subject/background masking.

Absolutely!! This would be incredibly helpful for portrait photographers. I use the subject mask feature constantly, but if I want to decrease clarity in the background, it also blurs the edge of the person's hair, clothing, etc., which makes the photo look as if it's not properly in focus. Being able to expand and feather the selection would solve this problem.

It was - this is now merged into the authoritative thread. 

Hi,

I often lack the possibilty to add some feather to a mask. If the mask is too harsh, which can be the case with AI masks for instance, it is rather painful to feather it "by hand" with a brush.
An additionnal feature of feathering would be IMO very handful.

I really think it will be useful if lightroom Masks could be feathered.

thanks

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.

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!

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.)

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.

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.
