Invert Mask on iPad Affinity Photo

[MartinKoss]

Hi. I just created a high pass layer but only want to apply the filter to a small area of my photo.

So I created a mask layer which, as you’d expect, starts off fully white. But I want to now invert that to a fully black layer so that I can brush with a white brush only where I want to apply the filter.

But I cannot find a way to INVERT a mask to black. I tried CMD + I as I expected to do the invert but it doesn’t.

What is the command to INVERT a MASK on IPAD AP?

Thanks.

Here you go, use the channels studio, select the high pass alpha mask then select invert.

Also a quick way is to add an empty mask layer instead of a mask layer. This works when creating a mask. The channels/alpha invert works Well with an adjustment layer or live filter when a mask layer in automatically created.
