P:(Masking) Right Click : Convert to Intersect & Convert to Normal

@richardplondon 

Intersection should be an Operator on its own.

It has been proposed (not by me but I agree with that suggestion)...I have given up on that and I don't expect Adobe to change things so we are going to be using Intersection as the result of Invert and Subtract.

Copy Settings on the other hand turns any existing component, in any state, into an Intersection.

It is very fast and efficient and produces always the correct result.

Just as a comment: while "intersect" can be thought of as a third kind of action (alongside "add" and "subtract"), it cannot be set explicitly for a mask component and AFAICT it does not need to be. A given mask component can either have Add / Subtract behaviour; and it can be Inverted / not Inverted. That's it.

When you opt for a brand new masking component to Intersect with what is already there: LrC simply sets Subtract action, and Invert state, for you. It's a convenience shortcut only, IOW. There's no separate 'Intersect' mode in its own right.

So this outcome is easy to achieve ourselves after the fact, once we've grasped what intersection (as an intended outcome) does actually mean.

IMO a button or shortcut that blindly (say) switched the invert state of an existing mask component and also switched its Add / Subtract mode, would not be reliably helpful towards an intersection result - there'd be a range of outcomes depending on the prior attributes of this mask component. Unpicking this could be arguably more complicated, than simply using the current controls in an aware manner.

I highly recommend to use Copy Settings by @johnrellis 

He implement exactly what I ask here.

As for  a way to Intersect or Subtract an entire existing Mask, not a component, I am afraid that is impossible now but I agree it would be great to have.

Hi,

I was wondering if it would be possible to implement a way of subtracting, adding and intersecting previously created masks by selection or via a drop-down from the mask list created in RAW and Lightroom Classic? 

I would find this a powerful and time-saving improvement of using the already very impressive masking system.

This could also be achieved with a  shortcut, with the Intersect modifier.

Alt/Option + click on component = converted to Intersect/Normal depending on its state.
