This document provides instructions for creating a dimensional looking sphere in Photoshop using gradient tools and layer styles. The steps include:
1) Adding horizontal and vertical guides to center a new layer.
2) Drawing an elliptical selection using the guides and modifier keys to create a perfect circle.
3) Setting the foreground and background colors and choosing a radial gradient with multiple color stops to mimic the shading of a sphere.
4) Applying a drop shadow layer style to further enhance the three-dimensional appearance.
