The lens hood is a common photographic accessory set in front of the camera lens.
It has the following functions:
1. In the backlight, side light or flash photography, it can prevent the entry of non-imaging light and avoid fog.
2. It can avoid the surrounding scattered light from entering the lens when shooting in front light and side light.
3. In lighting photography or night photography, you can avoid the surrounding interference light from entering the lens.
4. It can prevent accidental damage to the lens, and it can also prevent fingers from touching the surface of the lens by mistake. It can also shield the lens from wind, sand, rain and snow to some extent.

Lens hoods are widely used in backlight photography, generally speaking, to avoid glare. However, if the light source is close, glare may still occur. At this time, you can use your hand to block the hood on the side where the light source is located. Whether the glare is eliminated, you can directly observe the effect in the viewfinder. In addition to the optical quality of the lens itself, the role of the hood is very obvious. The color, sharpness and contrast of the picture without the hood are not ideal, and the picture with the hood has good performance in several aspects. With a small hood, the effect is very different.
