30-Second Photoshop: Double Up On Layers

The original image was overexposed, so we added
an adjustment layer in Photoshop CS4 to darken it
(detail, left). It still seemed too light, so we doubled
the effect (right) with a quick keyboard shortcut.

When creating an adjustment layer
to alter, say, brightness or contrast,
you can quickly double the effect
if the adjustment doesn’t go far
enough (as in the photo at near
right). simply press control + J (command
+ J on a mac) with the layer
selected. it instantly duplicates the
layer, doubling the effect of the first
adjustment (at far right). if it’s too
much, dial down your new layer’s
opacity to achieve a look you like.
