Let Photoshop Do The Work In Curves

 

Let’s say you’re using the Curves dialog for correcting images and you have an image where you’re trying to adjust the color of some green plants. How do you know where that particular green “lives” on the curve so you can dial in and adjust it? Photoshop can tell you—in fact, you can have Photoshop automatically plot that color on the curve for you. With the Curves dialog open, just Command-click (PC: Control-click) on that color within your image. Photoshop will then add a point to the curve that represents the spot you sampled, and now you’re ready to tweak it.

Invert to Alpha

When working with vector - created art and the source art is unavailable, modifying the art to create a logo can be a pain, to say the least—particularly when it’s flattened and the background needs to be knocked out.  A careful combination of Invert (Command - I [PC: Ctrl - I]), Color Balance (Command - B [PC: Ctrl - B]), and layer Blending Options (Control-click [PC: Right-click] the layer name) can yield simple background knockouts of one- or two-color logos without making a mess.
