Idea for brush selection>invert mask option

[Abhiishek]

Last night working on Lightroom Cc, I realised a missing feature. I was editing an image of bird on grass. I wanted to darken the grass to create contrast. SO I used selective edit>brush selection. Masked the bird, and was hoping to have invert option to select bird surroundings. But unlike Radial filter, INVERT FEATURE IS MISSING.

Hope Adobe adds this feature, as it could really save time.

In the mean-time until Invert is added as a feature-Try a work-around method:

1) Apply a linear Gradient over entire photo, (Start outside image & drag AWAY from image)

2) Select the eraser- to erase the gradient adjustment (from the bird!)

Increase the brush size as much as you can, turn off Auto Masking and paint the entire image. That will take only a few strokes. Now switch to the eraser and you've got what you want.
