Find Highlight and Shadow in Photoshop CS5 Images

Using the Curves panel in Adobe Photoshop Creative Suites 5, you can fix an image created in less-than-perfect lighting. The first thing you need to do in the Curves panel is determine the lightest and darkest parts of the image — referred to as locating the highlight and shadow:

  1. Before starting the correction, click the Set Black Point eyedropper once.

  2. Hold down the Alt (Windows) or Option (Mac) key and click the shadow input slider.

    When you Alt-click (Windows) or Option-click (Mac), the clipping preview turns on, revealing the darkest area of the image.

    If you don’t immediately see a dark area in the clipping preview, you can drag the shadow input slider to the left while holding down the Alt key or Option key. Note where the darkest area of the image appears.

  3. Hold down the Shift key and click directly on the image in that dark region.

    This step drops a color sampler on the image that helps you reference that point later.

  4. Repeat Steps 1 through 3 with the highlight input slider. Select the Set White Point eyedropper in the Curves panel.

  5. Hold down the Alt key or Option key and click the highlight input slider.

    Again, you can drag the slider toward the right if the lightest point doesn’t immediately show up.

    When you locate the lightest point, as indicated by the lightest point in the clipping preview, you can Shift-click to drop a second color sampler.

    You can Alt-click or Option+Shift-click to drop a color sampler.
