What is the use of camera hood and how to use it?

the main function of the SLR hood is to prevent harmful light from entering the lens from the side. We shoot in light environment, and the hood has no function. When shooting in side light and backlight, its function will be highlighted.

SLR hood is suitable for shooting night scenes, and the role of lens hood can not be ignored, especially when shooting city night scenes.

there are two kinds of p>DSLR hoods, one is a round hood, and the round hood is long and short. A long hood can avoid the interference of surrounding light sources and is usually used in conjunction with a telephoto lens. Short round hoods are usually used on wide-angle lenses. When the hood is useless, it can be installed on the lens in reverse, which can save the space in the bag. In addition to shading, the hood can also protect the lens to some extent.

for example, it can block dust and water mist. Sometimes, the camera will accidentally bump. There is a hood that does not let the lens directly touch the object to protect the lens from being broken for the first time. Therefore, according to your personal habits, you don't need to install a hood when you are not using it, but under special circumstances, it can still help your camera take better photos and protect your camera.

the light source is complex, and street lamps or ceiling lamps are all point light sources, which are easy to cause ghosts or light spots and affect the imaging quality. The hood can block part of the side backlight that enters the lens from nearby, thus reducing the probability of ghost or light spot.
