Render filters

The Clouds filter generates a soft cloud pattern using random values that vary between the foreground and the background color in the toolbar.

Difference Clouds

The Difference Clouds filter uses randomly generated values that vary between the foreground and background color in the toolbox to produce a cloud pattern. The first time you choose this filter, portions of the image are inverted in a cloud pattern. Applying the filter several times creates rib and vein patterns that resemble a marble texture.

Fibers

The Fibers filter creates the look of woven fibers using the foreground and background colors. You can control how the colors vary with the Variance option (a low value creates longer streaks of color, while a high value makes very short fibers with more varied distribution of color). The Strength option controls how each fiber looks. A low setting creates spread out fibers, while a high setting produces short, stringy fibers. Randomize changes how the pattern looks; you can select this option until you find a pattern you like. When you apply the Fibers filter, the image data on the active layer is replaced with fibers.

Lens Flare

The Lens Flare filter simulates the light refraction caused by shining a bright light into a camera lens. You can set the flare brightness, flare location, and flare shape (the lens type). Click in the preview window in the dialog box to set the flare location.

Texture Fill

The Texture Fill filter uses a grayscale Photoshop image as a texture for an image.
