Adding a layer mask using an existing layer

[Dean Fritzel]

I have 2 layers. One is a photo, and the other is a black and white layer I want to use as a mask for the photo. How do I do this?

TIA

one way is to create a layer mask (click add layer mask in the layers palette) then copy the black and white layer data into the mask.

on the B&W layer
make a selection of the black or white areas (select color range)
then hit the mask icon at bottom of layer palette
you might want to inverse the selection first depending what you wanted to
mask off

Though probably an extra click, or two, you can create your Selection, as KatWoman suggests, then choose Selection>Save Selection and choose Layer Mask. This has the added advantage of allowing you to easily Invert.

As I use this method most often (old habits), I often forget about the icon, that Dave mentioned.

there are at least 3 ways to do anything in photoshop! :)

Don't forget ctrl+alt+2 to load luminosity selection. May work better than color range.

... and I can think of a fifth. But let's not get carried away. ;)
