What cameras and materials are needed for light painting?

Light painting: also called light painting photography. As the name implies, it is a photographic work with light painting as the creative means. If you want to do simple illusory light painting, you can shake the camera, but the effect will be difficult to predict and you need to try many times. The light painting photography mentioned here refers to recording the patterns drawn by luminous objects (such as flashlights, candles, light sticks, mobile phones, etc.) under the long-term exposure of the camera. Although the principle is not complicated, it takes some brains to come up with new ideas. Shooting methods and techniques: 1. First, you need to draw a design sketch and draw your own ideas first. Because under long exposure, the noise control ability of the camera will be weakened with the increase of time, and the noise will be more and more, so it is necessary to minimize the time of light painting to obtain better image quality; 2. Use an all-black background or in the dark, and avoid contact with other light sources (street lamps, etc.). ), which is beneficial to capture the trajectory of light painting; 3. You must use a tripod, and the shooting process in light painting photography creation may take a long time, so you need to use a tripod to fix the camera; 4. Brush for light painting-flashlight, candle, light stick, mobile phone can be used, but generally choose a stable brush, and unstable candles are generally not considered; 5. It's best to release the cable, so that you can get a longer exposure time (using M file, the slowest shutter speed can only reach 30 seconds), and the process of light painting is generally about 30 seconds, which means that the exposure time is set to 30 seconds; 6. Choose a large aperture, so that the trajectory of light painting can be blurred and the effect will be better; 7. Fix the camera, brighten the background you want to draw, focus with the camera, and then adjust the focusing mode to manual to keep the focal length unchanged; 8. You can use your imagination at will when you start light painting, but remember to highlight the subject with a flash after painting, otherwise you can only see the trajectory of light painting; In fact, the process of light painting can be completely imagined as: in the darkroom, the creator outlines the outline of the subject with luminous objects, and fills the outline with colors with luminous objects of other colors to enhance the visual effect, that's all.
