How to use the bull shield

One is a round head cover, which 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 for wide-angle lenses.

The second hood is petal-shaped. Generally, the upper and lower petals are long and the left and right petals are short. This is for the convenience of framing and shading. Sometimes you will see a square hood, which is rare.

As the name implies, the hood is used to block light, and its main function is to prevent harmful light from entering the lens from the side. When we shoot in a light environment, the hood is useless, and its role will be highlighted when shooting in side light and backlight.

It can also protect the lens, which may be appreciated by people who have fallen off the lens. Once when I was taking pictures outside, the camera hit the wall and the lens was disfigured on the spot. If there is a hood, it should be avoided.

When the hood is useless, it can be installed on the lens in reverse, so it can be put in the bag to save space. In addition to shading, the hood also has a certain protective effect on the lens, such as blocking dust and water mist. Sometimes the camera accidentally bumps, and a hood will not directly let the lens touch the object, which will protect the lens from being broken at 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.

In night photography, the role of the hood can not be ignored. Especially when shooting city night scenes, the light source is complex, and street lamps or roof lighting are all point light sources, which are easy to cause ghosts or light spots, affecting the imaging quality. However, the hood can block part of the side backlight from entering the lens from nearby, thus reducing the probability of ghosts or light spots.
