2 CHECK
FOR CLIPPING
You usually want to use the full tonal
range from black to white, without
losing details in highlights or shadows. Hold
Alt while dragging the Whites or Blacks in
the Basic panel for a view that shows clipped
pixels as you drag – bring both sliders to a
point just before the pixels begin to clip.
3 VIBRANCE
FOR SUNSETS
Often a sunrise or sunset displays
strong colors around the sun, while
those further out are less saturated. You
want those colors to pop, but if you increase
Saturation you risk pushing the strong colors
too far. Instead try Vibrance, which targets
and boosts only the less-saturated colors.
4 CHECK FOR
COLOR CASTS 5 FIX UP
THE FRINGING
Sometimes your camera’s white
balance isn’t entirely accurate, but
you can use Lightroom to ix a color cast
in seconds (especially if you shoot raw,
which means you can set the white balance
afterwards). Simply grab the Eyedropper next
to White Balance in the Basic panel then click
over a neutral point, like a rock or a road. Wide-angle lenses are susceptible to
chromatic aberration, which causes
color fringing along high-contrast edges. Go
to the Proile tab in the Lens Correction panel
and check the box to ix it. To enable the ix by
default on all imported images, check the box
(and alter nothing else) then hold Alt and click
the Set Default button in the bottom-right.
