What is the function of ZLDS 100 range hood?

The hood is a common photographic accessory set in front of the lens, which is made of metal, hard plastic, soft rubber and other materials. Its function is as follows: 1. When shooting with backlight, sidelight or flash, it can prevent non-imaging light from entering and avoid fogging. 2. When taking photos with forward light and side light, the scattered light around can be avoided from entering the lens. 3. In lighting photography or night photography, you can avoid the surrounding interference light from entering the lens. 4. It can prevent the lens from accidental damage, prevent fingers from touching the lens surface by mistake, and shield the lens from wind, sand, rain and snow to a certain extent. Sheyuan net
