Step 5 Let’s import another image. This one is of a metalic skull I found at Place it in your design in a layer called ‘Skull’, and move it so it’s beneath the face. Add a new layer and fill it with black, then change the blending mode to Screen. With the Brush tool (B), start painting over the teeth, in order to make them white.

Step 6 Select the ‘Skull’ layer and go to Image > Adjustments > Levels. Use 0, 1.40 and 255 for the Inputs. There’s a huge highlight spot on the forehead that we want to remove. Add a new layer called ‘Gray’ and select a gray color of the skull with the Color Picker, then paint over the highlighted area with the Brush tool (B).

Step 7 Let’s add another image for the nose, this time of a computer power supply fan. You can find it at Name the layer ‘Fan’, place it over the nose, and with the Polygonal Lasso tool (L), select the nose area and mask the ‘Fan’ layer.

With the ‘Fan’ layer selected, go to Image > Adjustments > Levels. Increase the black input to 25, change the grey input to .95, and for the white output, change this to 176.
