An ND (Neutral Density) Filter is like sunglasses for cameras. It's a special piece of glass or resin that professionals put in front of camera lenses to control how much light enters the camera. Think of it as a tool that helps camera operators film beautiful shots even in very bright conditions, like outdoor scenes on sunny days. It's similar to how sunglasses help us see better in bright light, but for professional cameras. This tool is essential for cinematographers and videographers who need to achieve specific creative effects or film in challenging lighting conditions.
