The Eye's Iris Muscle Strands
Experimenting with a macro lens and side lighting through an eyeball reveals the multiple strands of papillary dilator & constrictor muscles, showing that the beautiful iris can actually be somewhat creepy when viewed too closely. The small lines and colors we notice within an iris are individual muscle strands used to pull the pupil open or closed. And layers of the corneal limbus appear as flawed ledges having jagged drop-offs around the exterior of the cornea, easily identified once lighting is angled across the eye.
This image is best viewed at it's largest size (1024px). Lighting was a 200w/s studio light thru gridded snoot, placed to the far left of subject's face (camera-right) to limit reflections. Canon 50mm f2.8 Macro lens on Canon 5D-MII.
