Applying Radial Ramps
The Radial Ramp Tool. Keyboard shortcut: Ctrl+R
Depth values vary from one selected depth value (Depth1) in the center of an ellipse, to the second selected depth value (Depth2) around the outside. Use Radial Ramps for hollows and bumps. Ramps do not have to be applied to circular objects.
Like all Depth Data Ramps, the Radial Ramp has to be applied to existing data. Paint Depth Data of any value over the part of the image you want to apply the ramp to. Use one of the Selection tools to select this part of the image. Select the Radial Ramp Tool. Select the two depth values (Depth1 (red, left) and Depth2 (green, right)) to use for the center and edges of this ramp.
Tip: A % symbol above the Depth Picker indicates that the Percent scale is selected. No % symbol means the Value scale is selected.
Tip: To quickly sample two depth values on the screen, press and hold the Alt key to select the  Eyedropper tool, then click and drag from one value to the next. Release the Alt key. Click and drag the mouse to create a circle anywhere in the selection. The first click will be used for the center of the lump or hollow, but it does not have to be drawn in the center of the selection.
Tip: You can get different effects by varying the size of the circle you draw.
Tip: If you do not like the effect you can simply draw another circle immediately.
