Title: can masks be linked together in PS?
Post by: button on May 02, 2008, 03:20:40 pm

Hello everyone,

I've looked around for this answer but have had no luck.  I would like to link two masks together (on two separate layers), such that as I "paint in" one of the masks with the brush tool, the other layer's mask is simultaneously painted off.  I could see this having quite a bit of flexibility if the brush opacity is changed.  Is this possible?  I played with clipping masks, but couldn't get what I wanted.

Thanks,
John

You can't.

what kind of layers would those be? there are workarounds on this issue...

I have an image with two separate masked "creative sharpening" layers, one with a 4 pixel radius high pass, and another with a 2 pixel radius high pass.  I want to paint in one while eliminating the other to allow for differences in edge spacial frequency, because I don't want to have both layers on top of one another at any one spot (too much sharpening).

Thanks,
John

So for example you have 3 layers, the image and on top of that hipass2 and hipass4, both with blending mode set as overlay. select the hipass4 layer, select blending options and change knockout to deep. that applies the hipass4 straight to the bottom layer, and the hipass2 is ignored. When you paint a mask to hide hipass4, you reveal hipass2.

That's excellent! Another way to work

You can also group layers, Alt clicking the line between the layers in the palette. The top layer, which is then shown indented, is masked by the layer mask on the layer below.

You could also put both of your layers in a folder. The apply a layer mask to the folder (select the folder , then Layer->Add layer mask). The mask then applies to all layers in the folder.
