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

If you see a shiny highlight on your subject’s lips, and you want to make it look glossier, duplicate the Background layer then change your layer blend mode to Screen to brighten the entire image. Option-click (PC: Alt-click) the Add Layer Mask icon to hide this brighter layer behind a black mask. Press D to set your Foreground color to white; choose a small, soft-edged Brush (B); and paint over those white highlight areas on the lips and they’ll get even glossier.

Did you know there’s more than one dash? In Photoshop, add a standard dash for separating clusters of words by pressing the Hyphen key. To add an en dash to show duration of time (e.g., Monday-Saturday), press Option-Hyphen (PC: Alt-0150).

If you have a text block with quotation marks, it’s standard to have them appear outside the text block so that the copy can line up.
