What do you use to block the camera for shooting basketball games?

If you want to block the interference of light and protect the lens during the shooting of a basketball game, you can use a hood. The hood was installed in front of the camera lens. Its function was as follows: 1. Blocking messy light: When shooting with front light, side light, backlighting, or flash, it can prevent surrounding scattered light and non-imaging light from entering the lens, preventing halos and fog from appearing on the screen, and improving the image quality. 2. Protect the lens: If the lens accidentally falls, the hood helps to reduce the damage of the fall and can block some of the rain from falling on the lens. The hood was divided into the original factory and the sub-factory. The original hood was more versatile and practical, and was usually designed in sync with the lens light path. If there were no special shooting needs, the original factory standard hood attached to the lens could meet most shooting needs. However, buying a sub-factory hood that matched the lens 'caliber and angle of view (such as the Meco hood) could also play a corresponding role. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
