Ask some questions about photography and take photos of the party with one lens.

Party documentary? There are many such situations: 1, the room is relatively small, the lighting on the scene is not very good, and the requirements for the lighting effect on the scene are not high. This one uses a flash, and this one doesn't use the flash on the camera. If you have less money, you can buy a lamp like Yin Yan. The effect is 4-500 yuan, which is better than the top of the machine. The room is small, so you can shoot the lamp at the ceiling and then use the reflected light. General sensitivity 400. 2, the room is relatively large, or simply outdoor. There is also a situation where a flash is used. In this case, regardless of the noise of photos, ISO is usually controlled by overhead flash, or there are professional lights and shutters for automatic metering. Slow down and make the background as bright as possible. The light with metering will automatically go out when the subject is properly exposed, and the shutter will continue to open, so that the subject and the background can be exposed normally at the same time. 3, you can't use lights at all. To shoot the lighting effect of the party scene, you need a larger aperture, try to use a wide-angle distance as close as possible, use a monopod or tripod, keep it stable, and maximize the sensitivity.
