Light Painting is a photographic technique made by moving a hand-held light source while taking a long exposure photograph, either to illuminate a subject or to shine a point of light directly at the camera, or by moving the camera itself during exposure. A person takes a photo of another person moving a hand held device with a flashlight. Then, in oder to capture the fast moving light the photographer needs to change the shutter speed and aperture. Light painting painting is so much fun to me because you never know what you are going to produce. The photo above was using 1/8 aperture giving time for the camera to be slightly moved creating a random effect using lights my friend made with his flashlight in the background.
In this image I was in my room late at night. I took this picture of me in mirror. My sister was behind me, tracing my body with a flashlight. This picture shows that a light painting picture doesn't have to be a cool design but it can involve a person too. When I took this photo the shutter speed was 15' and the aperture was 6.3'. I tried different shutter speeds and apertures to get the perfect image. The one I used in the photo below is the best and allowed for a unique light painting.
