To learn about how to draw with light, I drew some of these photographs including the flower (bottom right), the person, and the strange square (bottom middle). I did not have my camera so had to be the one to draw some of these images.
This experimenting showed us as a class how to set up our camera’s, controlling the Shutter speed, setting it to bulb, controlling the aperture, setting it to a small F. number, and controlling the ISO setting it as low as possible. It is important when taking a photograph of a moving light source to use a tripod so the image will be as crisp and accurate as possible. Another factor to bear is to focus the camera manually, as most camera’s will struggle to focus in dark conditions.
