PHOTOSHOP TIPS
Building color tables
This is an old trick to 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
QUICK TIP
Speeding up your batch actions
If you’re running a Batch action on a folder full of images, one of the things that can really slow the process down is the fact that the History palette keeps creating History States (undos) for each image. To keep your Batch actions running at full speed, there are two things you can do: In the History palette’s flyout menu, under History Options, turn off the checkbox for Automatically Create First Snapshot. Secondly, go under the Photoshop menu, under Preferences, and choose General (in Windows, Preferences can be found under the Edit menu). In the History States field, lower the number from 20 (the default) to 2 and click OK, then your Batch will run like a greased pig. Don’t forget to increase your History States or change your History Options back after you’re done batching or you’ll be down to two undos.

Color Replacement options
To get the very best from this tool, you need to understand the Sampling and Limits options
The Color Replacement Tool’s Sampling options determine which pixels are recolored and which are left unchanged, based on their original color. If you select Once, only the color sampled when you first click, and those within the specified tolerance range, will be replaced as you hold down the mouse button and drag, and a new color will be sampled each time you click. If you select Continuous, the tool will continually sample the color directly beneath the crosshairs as you brush, and replace all of those colors, and those within the tolerance range, that fall under the brush stroke. The results can vary dramatically, and if you don’t use the right setting, things can quickly get out of control. So start out using a low Tolerance setting and work on areas of high contrast to get a feel for how thios option works. The Background Swatch option limits the targeted areas to those that contain the current background color. Using a low Tolerance setting with this option is the easiest way to constrain the effects of the tool.
