I would like some help with this, I have been going around in circles. I would like to select two adjustment layers at once to apply a brush on teeth. I have created one adjustment layer of hue/saturation ( saturation 0 on the yellow) and also a brightness/contrast layers ( brightness + 20 ). I would like to apply both layers at once when I brush the teeth and not go one layer by layer. I am attaching a screen shot of the two I wish to select at the same time but it won't let me it says " warning no pixels selected ". I have got a feeling that it should be easy to accomplish but I cannot find the answer. I know I can do one at a time but I just want my workflow to go faster.
