How to emit a light beam

2. Stage lighting; 3, ordinary light source (such as flashlight lighting, etc.). ). The main things that can give people a strong sense of beam are shed light and stage lighting. 1. Use manual exposure mode. In my experience, only in manual mode can you expose according to the photographer's intention, instead of giving it to the camera for exposure in aperture priority mode. This kind of camera often measures more light automatically than manual exposure, which leads to overexposure. 2. Use spot metering. Spot metering will darken the background and highlight the light beam, which can distinguish the light and dark parts more accurately and clearly. When metering, we should pay special attention to an important issue, that is, metering position, which is the key to ensure accurate exposure. I often put the metering point at the edge where the light source contacts with objects, such as people under stage lighting, and measure a little inside the edge of the face, so as to ensure that the face is exposed clearly and the light beam will not be too bright to lose its texture. Of course, the position I'm talking about is a general position. As for the specific shooting, we can take more photos according to the specific lighting conditions and find out the best exposure parameters, which is also necessary. 3. Try to use a tripod. If possible, try to use a tripod, especially under the stage lighting. The light source is often very complicated and needs a tripod to stabilize the camera. 4. Find a good shooting angle. The purpose of choosing a good shooting angle is to apply light correctly. In the application of light, side backlight or side backlight is generally used, and backlight is also used, but it is difficult to grasp. Use less forward light, so that the objects in the forward light are bright and lack of contrast between light and shade. I think it should also be pointed out that don't shoot with the overhead flash that comes with the camera, which is often a way that novices like to use. Improper use will destroy the texture of the work. As for some people who say to shoot with a small aperture, I haven't realized the necessity of using a small aperture, so I won't say it here. What is discussed above is the shooting method in general. If you are a professional or a photographer, you can also take the following measures to enhance the beam effect of your work: 6. Make full use of objects such as gaps between leaves and trees. In these objects, it will be easier to shoot the beam effect. 7, conditional can artificially fill the light of the subject. For example, the application of reflector often has a good effect. 8. use RAW format.
