This is an iris texture I created for use in creating realistic 3D eyes. It was created completely in CG; there are no real-life textures used. I noticed a lack of really nice iris maps on the web and created my own to suit my needs. The file is 1152px (16inches x 16inches) square and is 72 dpi. If you create your 3D eye with a contracted pupil, the texture will move easily to full dilation. Enjoy.
