Depth Cue
From ZBrush Info
Rendering with depth cues is only available in Best Render mode. Depth cues cause the image to be rendered with different levels of bluriness at different depths. This can be used to, for example, simulate the effect of a lens that focuses sharply at only one depth, or atmospheric haze that causes distant objects to appear blurrier.
Depth Cue Alpha: You can modify the depth cue effect by using Depth Cue Alpha. Click the Depth Cue Alpha patch to access the texture sub-palette and choose a texture. It will be converted to grayscale alpha and stretched over the entire canvas area. Each pixol of the alpha will determine the intensity of the depth cue at that location. White areas give the strongest depth cue effect, black areas give no effect. Useful for restricting the depth cue effect to a selected area of the canvas.
Intensity: Sets the intensity of the blur at its far point. Range = 0 to 100%. Default = 100%.
Softness: The number of pixols averaged to produce the blur. Higher numbers produce more blur. Range = 1 to 8. Default = 4
Depth1: Depth1 is the near point of the depth cue effect. There is no blurring at this distance. The blurring begins as depth increases. Type in the Z depth directly or click and drag from the slider to the canvas to set the value; pick an object at the depth where you want the depth cue to begin and release the mouse button.
Depth2: Depth 2 is the far point of the depth cue effect. There is full blurring at this distance. Type in the Z depth directly or click and drag from the slider to the canvas to pick a depth.
On the left, a fish rendered without depth cuing. On the right, the same fish rendered with Depth 1 set on its nose and Depth 2 set on its tail.
Depth Cue Curve: Clicking on the collapsed Depth Cue Curve area of the sub-palette expands the Depth Cue Curve to its full size. You can adjust the intensity of the depth cue between the near point (Depth1) and far point (Depth2) by adjusting the curve.
Note: By setting a high depth cue intensity at each end of the curve, and a low intensity at an intermediate point, you can achieve a "lens effect", where depths both in front of and behind the focal plane of lens of the virtual camera are blurred.
