Painting With Light
This is one of my favorite methods of creating an image. Very literally, you paint your subject with light using any one of countless illuminating tools: flashlights of varying size, strobe units, speed lights, modified LEDs, etc. Anything that can cast or shine light is an option.
The post-processing is rather intensive with some images having as many as hundreds of layers. Most of these here are not that deep, but they still can take hours or days to edit.
