“How did you light the eyes?"
Lighting the eye sockets was a particular challenge. Normally I diffuse LED's with a clear lens made from acrylic or such. After testing many variations I came to the conclusion this was not an option due to the fog needing to pass through the sockets.
Turns out the solution I found was super simple. I glued the micro-LED's directly to the skull in a circle around the sockets. There are seven LED's per eye and it lit up pretty well. The LED's were hidden and no visible hot spots could be seen. But it needed something more to look great and I needed a way to direct the fog up through the sockets.
I decided on adding a backer to the sockets by using concave shaped pieces of eva foam. I wanted the light to bounce off the backer so I tested the eva covered with aluminum tape. I wrinkled the aluminum up and it looked great with multi-directional lighting reflections. I also painted a light wash of acrylic blue over the aluminum. That way even if the LED's are washed out by daylight the sockets are still a reflective blue.
It really looks better than I would have imagined. At times, in the right light, the aluminum appears to be gems.
Sometimes the simplest solutions are the most rewarding.
