[Function] Lens hoods are needed whether traditional or digital. When your lens is facing the direction of the sun, since the lens is generally a combination of multiple groups and multiple lenses, It is easy to produce flares, halos, and glare. Sometimes it makes a certain area of ??the photo appear white, sometimes it produces some halos. There is a hood. These situations can be avoided. Traditionally, it is not good to have halos on photos. Different lenses have different anti-glare capabilities, some are easier to produce, and some do not have a hood. The main functions are as follows: 1. It can prevent the entry of non-imaging light and avoid fog when shooting in backlight, side light or flash photography. 2. It can prevent the scattered light from entering the lens when taking photos 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 touching the surface of the lens by mistake. It can also shield the lens from wind, sand, rain and snow to some extent. The hood is widely used in backlight photography, generally speaking, it can avoid glare. However, if the light source is close, glare may still occur. At this time, The hood can be blocked by hand on the side where the light source is located. Whether the glare is eliminated, you must observe it clearly in the viewfinder. |
