Using a digital camera, adjust the shutter speed (how fast it will open) and aperture (how big it will open) using the 'TV' or 'S' symbol, setting the exposure for a relatively long time (e.g. 4 seconds). Make sure you are in a dark location with little or no light. To avoid a blurry picture, the person holding the camera must stay still. Once you open the shutter, your picture is exposed. Here, use a flashlight (e.g. cell phone) as a paint brush to draw a picture. Keep moving the light around in order to spread an even amount of light. This is known as painting with light. The above picture of a butterfly is an example, created in class today with my teammates.
