Applying adjustment layer to a group of layers

[reindeer4]

Is there a method to apply an adjustment layer to a group of layers?

I have a curtain on one layer of a Photoshop CS4 document.

I duplicated the curtain twice and repositioned the copies.

Now I'd like to use an adjustment layer to change the color of my curtains without affecting the rest of the composition (and I can't move the curtains down to the bottom because they need to sit above other elements).

I tried grouping my 3 curtain layers together and then applygin an Adjustment Layer>hue>colorize - but that's affecting the whole composition.

And when the layers are grouped, holding ALT while hovering between the adjustment layer and the group does not bring up the special icon that lets you apply the adjustment just to the layer beneath it.

Would apprecaiate andive on how to apply an adjustment layer to a group of layers.

(I can go back and apply my adjustment to the original curtain then reduplicate and reposition, but would have to repeat that procedure every time change color preference).

Thanks?

Put your layers in a folder, and change the folders blending mode from pass through to normal. You can then put an adjustment layer on the top of the layers in the folder, and it will only affect what is in the folder.

Perfect!  Just when I thought there was no use for "normal" mode...

Hi Mike, 

I must be doing something wrong, because as soon as I select the Normal blending mode, the adjustment layer no longer works at all. I am trying to use the Levels adjustment on just the layers in a group and it is not working.
