The role of the hood:
The hood is a commonly used photographic accessory set in front of the camera lens. There are many materials such as metal, hard plastic, and soft rubber. Its functions are as follows:
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 with forward light and side light.
3. In lighting photography or night photography, it can prevent the surrounding interference light from entering the lens.
4. It can prevent accidental damage to the lens, and it can also prevent fingers from accidentally touching the surface of the lens. 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 quite different.
There are many sizes of hoods, and the one that matches the focal length of the lens should be selected. The shorter the focal length of the lens, the larger the angle of view and the shorter the hood. If the hood of a standard lens is used on a wide-angle lens, it will inevitably produce the consequence that the image around the screen cannot be imaged. On the contrary, it cannot play the role of the hood. When using a zoom lens, it can be equipped with a self-use retractable lens hood.
