It has not been the most productive day (so far at least). Still, I learned one thing I want to post about. Few times I wanted to do that and had no idea how to.
Paste a layer(A) into a layer(B) mask. In 4 easy steps:
1. select the layer A and copy it to clipboard (Cmd/Ctrl+a, Cmd/Ctrl+c)
2. go to the layer B, make it active and click the Layer Mask
3. go to your Channels Panel, there is your mask in the bottom, set it active and visible, paste the clipboard content (Cmd/Ctrl+v)
4. make the mask channel invisible again and the RGB channel (top) active
And it’s done!
I played a bit with halftones today (Filter > Pixelate). I followed the Photoshop Guys’ and applied it in grayscale (all 4 channels parameters equal). I’m not too happy with what I got, but a post needs an image.
