Photoshop CS5 Top 5: HDR Pro

High dynamic range lets you extract every last luminance variation from your digital photographs. CS5's HDR Pro lets you combine two or more bracketed photos into an image that resonates with detail and depth.

Photoshop Top 40, Feature #9: Levels

The Levels command, and its cohort the histogram, let you adjust luminance levels on a channel-by-channel basis. The upshot is that you can increase contrast, correct for color cast, and make a bad image good.

Photoshop Top 40, Feature #19: Luminance Blending

Deep inside the Layer Style dialog box are two slider bars, This Layer and Underlying Layer, that let you blend pixels by brightness. Despite their dull names, these sliders rank among the most powerful features in Photoshop.

Photoshop Top 40, Feature #23: Color Range

If you use the magic wand tool, stop what you're doing and switch to Color Range. This outrageously useful command lets you select an image as easily as the wand. But with more flexibility and much better results.

Photoshop Top 40, Feature #24: Curves

Where luminance is concerned, no feature gives you greater control than Curves. It lets you reign in highlights, open up shadows, and reveal all points in between. Curves takes a bud of an image and makes it blossom.

Photoshop Top 40, Feature #36: Black & White

In the digital age, we shoot linear images that are converted to full-color photographs. Which is a good thing, because it means we can distill the perfect black-and-white shot in Photoshop, one range of colors at a time.
