Modifying layer effects with contours

You can use contours to shape the appearance of an effect over a given range in the Drop Shadow, Inner Shadow, Inner Glow, Outer Glow, Bevel and Emboss, and Satin effects when creating custom layer styles. For example, a Linear contour on a Drop Shadow causes the opacity to drop off in a linear transition, while a Custom contour can be used to create a unique shadow transition. Custom contours created in Photoshop can be used in ImageReady.

You can select, reset, delete, or change the preview of contours in the contour pop-up palette and Preset Manager. For more information,
