How to take a detailed photo of light graffiti (light painting photography)? ? three

at least two friends can cooperate with each other to complete it, so it is more varied and interesting. Light painting photography can be done indoors, at night, or even in some dim light environment where it is impossible to take pictures at all. It does not need a special camera or lens, and almost everyone can take pictures. Preparation for light graffiti: 1. Two people are needed, one to take pictures and the other to draw patterns with light; 2. Prepare a flashlight, camera and tripod. If you don't have a flashlight, you can replace it with a mobile phone screen. If you don't have a tripod, you can also put the camera on a stool, table or railing. Light graffiti photography skills: 1. Take out the above props where you can't see your fingers; 2. Turn the camera to M, and the focusing mode is selected as manual; 3. Adjust the sensitivity to ISO1, the shutter speed to several seconds, and the aperture is about 8; 4. The photographer presses the shutter, and another friend is opposite the camera, drawing any pattern you want in the air with a flashlight! 5. Look at the photos! If the photo is too bright, reduce the aperture a little, if it is too dark, enlarge the aperture a little, and then try again! Tips for light graffiti: 1. Using ground reflection will have a surprise effect; 2. Wrap the toilet paper in front of the flashlight and paint the toilet paper with various colors, so that beautiful colored light graffiti can appear; 3, remember! The words should be written backwards! Considering that light painting must be exposed for a long time when shooting, a camera with B-door shooting mode is necessary. This is a necessary condition. Generally speaking, most digital SLR cameras, as well as single-camera and micro-single-camera, have this B-door mode, which is generally set in manual M-file. The shutter time is set to the slowest setting according to the user's freedom, and there is no need to set the number of seconds to be exposed before shooting. For light painting, because many creations need to be composed of a series of actions, it is impossible to predict the length of exposure time in advance, so switching to B-door exposure can greatly improve the freedom of shooting. In addition to B-door, some high-end models also provide a more advanced T-door mode. The specific principle is to press the shutter to open and then press the shutter to close, so it is easier to operate. The NEX-5, as a demonstration prototype, is equivalent to enabling the T-door when using the wireless remote control in the B-door mode. The picture below shows the domestic cottage remote control used by the author. As for the question of where to sell, this is well understood and will not be explained.
