Light painting, or light drawing, is a photographic technique in which exposures are 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. The technique is used for both scientific and artistic purposes, as well as in commercial photography.
You need to know two things: aperture and shutter time. Aperture is how much light you let into the camera. Shutter time is how long you allow that light to go into the camera. To Light Paint we want to decrease the amount of light we let in the lens of the camera, while increasing the amount of time the shutter stays open. The longer the shutter of the lens stays open, the more action it can capture in one still image. Every camera is different, as is every photography scenario. Play around with your camera until you get the desired look you want for your photo.
The Light Painting Stick uses 8 AA batteries or a 3 cell LiPo battery.
The Light Painting Stick has two lengths.
1 meter tall: 144 RGB LEDs
2 meter tall: 192 RGB LEDs
You need a camera with manual mode. If your camera is on autofocus, it will get stuck adjusting focus and you won’t be able to get a picture. You need a tripod to stabilize the camera. You can use anything in place of a tripod, a box, or even a dresser drawer. You need a dark place and a focused light source. Depending on what you are shooting, you can use a large floodlight, small penlight, or even glow sticks. As long as you have a light source whose beam of light can be directed at the subject of your photo, you are fine.
