Invert Mask bug?

Permanently deleted user

First, create a fill adjustment layer and adjust the mask range within the luminance range.
After that, create a new layer, copy the mask from the previous layer, and then "Invert Mask" will not invert it.
To try another way, I copy the mask, check the "Invert Range" checkbox in the luminance range, and press "Apply", which momentarily inverts the mask, but the result is not inverted.
Is it possible to invert a mask created in a luminance range?
By the way, when creating a layer mask from the color editor, the mask can be inverted after copying it to a new layer.

But that too cannot be inverted when using a luminance range.

    It's your technique.

    Either rasterise your original mask before copying it, or rasterise the copied mask before inverting it.

    Thank you for the information.

    @Shane - Not so. I've just noticed this problem with 22. Rasterize mask, or not, it will not invert. I've brought a wedding session away with me on holiday to edit and am stuck on this, compared with my normal workflow. Which did not require, IIRC, a mask to be rasterized in order to invert. 

    [edit] Possibly it may be to do with the Surface Pro I'm attempting to use...

    [edit 2] OK - it doesn't invert on one image, but does on another. The one it wouldn't invert with I used a combination of 'magic brush' and normal brush to build the mask. (And rasterized, not that I normally have to).

    I was confused because I could no longer do what I used to take for granted.
    Rasterization was not necessary for this series of reversals.
    I guess it's a bug.

    Inverting a mask can work very confusingly if you have a luma range applied. Imagine that you draw a gradient mask to cover the top half of a landscape image, and also apply a luma range to it so as to mask only the bright sky, but not mask some dark mountains. If you invert the mask, you will not get the inverse of the mask you see because it will behave as if you now have a gradient on the lower half of the image, but the luma range will still be including the bright parts (of the lower half) and excluding the dark parts (of the lower half). So with the mask inverted, the mountains will still not be masked.

    But if you rasterise the mask as suggested, you get a mask that is as if you had painted it in on the sky only, excluding the mountains. And then if you invert it, you will get everything except the sky (and it will mask the mountains) because it is no longer affected by the luma range.

    Invert mask doesn't work. I just installed 23 and the first time I tried invert mask it worked. Since then not. First thing I do is to create a new layer and then a new mask in that layer by using the ordinary draw mask tool. Second, fill that mask. Third, create a new layer, copy mask from the first mask, then invert mask. In stead of an invert mask I get a filled mask. Rasterize doesn't help. Bug?

    I am also using 23 and tried the same thing and it reversed properly.
    Are you working while checking the mask display?
