Rendering a More Luminous Iris  
with Rob Silverman

Light and luminosity help create a more realistic eye.

1. HIGHLIGHT

Highlight in the iris should appear at the upper right of the pupil if the light source is coming from the upper right.

2. CATCHLIGHT

Catchlight appears on the lower lid at the opposite direction from the light source. This reflects light into the lower left portion of the iris

3. REFLECTED LIGHT

The lower left portion of the iris is lighter than the rest of the iris—creating a luminous effect. It is being lit by the ‘catchlight’ at the left portion of the lower lid.
