Emboss Type

• Emboss

  This changes the colors in your image to grayscale and the relief is more pronounced, looking like metal. Although the image looks grayscale, its color mode is not changed. In most cases this means it will stay RGB, but you can also use this filter on Indexed and Grayscale images.

  Bumpmap (preserve original colors)

  Relief is smooth and colors are preserved.

Azimuth

This is about lighting according to the points of the compass (0 - 360). If you suppose South is at the top of your image, then East (0°) is on the left. Increasing value goes counter-clockwise.

Elevation

Elevation is the height from the horizon (0°), in principle up to the zenith (90°), but here it means up to the opposite horizon (180°).

Depth

Bumps are higher and hollows deeper when Depth increases.
