Writing with Light
I set ISO 100 for low light sensitivity to minimize noise. Using a slow shutter speed, I allowed more light into the lens. I put the aperture to f/8.0, so the detail in their faces could be seen. My participants first held their cell phones under their chins to illuminate their faces when I pressed the shutter release button; then, they started to write. I have always wanted to capture light writing. I never knew how.
