What exactly is your target?
For the grad tool you can simply position it the other way round / turn it. Why would you need an invert option?
Please explain in more details, maybe I don't get your point
As above why would you need an invert option for either of those 2 things you mention?
I don't see a need for an invert command for the adjustment brushes.
The grad tool has the SAME invert shortcut key as the radial filter (the apostrophe ') .
My "target" is an invert function. So OK, you can rotate the grad tool, good enough. It didn't dawn on me.re I want to see it.
The adjustment tool is really where I want to see an invert button. Many times it's far easier to mask around something by masking the item itself, especially if you use the AUTO MASK function, and then simply invert the mask. I do this all the time in Photoshop using either a selection tool or if I make a channel sep. Unfortunately there's no option to invert the channel in LR.
You describe painting in a subject item (e.g. using automask), and then inverting the whole mask.
The same end result can be achieved differently: first paint over the whole picture, and then erase out the subject item (Erase offers all the same brush controls, as painting does - e.g. automask) ...or, if it is easier, brush-erase the subject item out of a grad adjustment which extends over the whole picture.
Either way, you've in the first instance defined where you DO want the effect... which has some superficial logic going for it at least.
All that said, a mask Invert button would certainly be handy. Perhaps one might want to duplicate a pre-existing brush adjustment 'pin', and then re-use that the other way around... or whatever.
It's already been Feature Requested, you can add your support there if you want: e.g
"The same end result can be achieved differently: first paint over the whole picture, and then erase out the subject item..." that's
You think that's a solution? Paint an entire area and then subtract? I know that's the only option given withing LR, but it's much simpler and faster to paint or select a small area and invert. I do this all the time in Photoshop with selections and channels seps. Seeing that the links you've posted date back to 2010/11, I guess this is a moot issue in the LR world.
Then I suggest you continue doing it in PS.
"You think that's a solution? Paint an entire area and then subtract?"
It's an available workaround that operates now. Do this out of a "grad" and it's pretty easy. Incidentally, I personally find that LR automask works BETTER in any case when erasing away from a boundary, than it does when painting up to it. So that's a practical consideration. Any "lumpiness" in application is far less visible where the mask fluctuates away from 0% strength, than it is where the mask fluctuates away from 100% strength.
But I didn't call it any kind of a solution to your particular issue of preferring to invert. To the contrary, I agreed with you about an "invert mask" button - except in so far, as I don't consider LR to be unusable without that.
This is just a user-to-user discussion forum here, nobody's actually obstructing you from getting what you want. At most, if people feel a proposal might affect the program's usability, or diffuse the clarity of its design principles, in a way that they personally would not like - they may express that opinion.
