Exercising Your Influence On GIFs

 

This is an old trick we use to influence how Photoshop builds its color table when creating GIF images. We put a selection around the area of the image that’s most important to us (for example, if we had a product shot, we’d put a selection around it), then we’d convert to Index Color (by choosing it from the Mode submenu under the Image menu). Photoshop will look at the colors contained in your selection and build the Indexed Color Table giving preference to those colors. It’s another slick way to use less colors, creating a smaller file, but with a better-looking image.

Imageready’s Supercharged Eyedropper

In previous versions of Photoshop, you could only use the Eyedropper tool to sample a color from other open images in Photoshop, but for some reason, ImageReady had a supercharged Eyedropper. If you clicked the mouse button within your image and held it down, you could leave your image window and sample colors from, well… just about anything—including your computer desktop or any other open application. Freaky! Fortunately, Adobe finally added this same power to Photoshop’s Eyedropper tool.
