Painting with Sunlight
Prismatic Mandala was painted with sunlight. Not with some brand of paint named sunlight, but real sunlight. By holding a glass prism, and directing the light into a darkened area of the studio onto a flat surface, I was able to paint a section of the above image while being recorded digitally on a Nikon D700 camera with a 28 – 105 mm Nikon lens. Although there were many tests before I got the right effect, the exposure was just 8 seconds long at f22. I used 10 layers and sections, plus the step and repeat method to complete the design with Photoshop.
