Original image

Filter “Emboss” applied

This filter stamps and carves the active layer or selection, giving it relief with bumps and hollows. Bright areas are raised and dark ones are carved. You can vary the lighting.

You can use the filter only with RGB images. If your image is grayscale, it will be grayed out in the menu.

#### 4.4.2. Starting filter

Preview

  All your setting changes will appear in the Preview without affecting the image until you click on OK. Don't keep Preview checked if your computer is too slow.

Function
  Bumpmap

    Relief is smooth and colors are preserved.

  Emboss

    It turns your image to grayscale and relief is more marked, looking like metal.

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

  That's height from horizon (0°), in principle up to zenith (90°), but here up to the opposite horizon (180°).

Depth

  Seems to be the distance of the light source. Light decreases when value increases.
