The sample size of the Eyedropper tool (I), found in the Options Bar, controls the size of the area that’s evaluated when it provides color and tonal feedback, but it can also a?ect how certain selection tools work—e.g., the Magic Wand or the Color Range command. The default Sample Size value is Point Sample, which samples a single pixel; however, this isn’t ideal for photo-graphs, where using 3 by 3 Average or 5 by 5 Average will give you better results.

If you have a multilayer composition and you
want to apply an effect to all the layers at once, don’t flatten the layers–use a composite layer instead. Hide the layers you want excluded, and press Shift-Command-Option-E (PC: Shift-Ctrl-Alt-E). A new layer will be created at the top containing a merged copy of all the visible layers.
Another option is to create a new layer at the top of the stack and make it active. Command-click (PC: Ctrl-click) each layer you want to include to make those layers active, as well. Press Option-Command-E (PC: Alt-Ctrl-E).
