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.
