The Invert mask option has gone missing in the latest LR CC version. There yes to be a checkbox near the bottom of the set of controls but it's not there anymore. Can someone tell me how to Invert?
The adjustment brush doesn't have that option.
Maybe you're thinking about the radial filter?
The invert mask option you are looking for is in Radial filter.
Please use Radial filter for Invert mask option.
The brush tool in the graduated filter also lets you remove parts of the overall effect, where not required.
