A polarizer is a specialized filter used in photography and cinematography to improve image quality. It's like sunglasses for cameras, helping to reduce glare, manage reflections, and make colors appear more vibrant. Camera operators and cinematographers use polarizers when filming outdoors to control how light appears in the shot, especially when dealing with water, glass, or sky. Similar tools include neutral density filters or UV filters, but polarizers are specifically valued for their ability to enhance visual drama in scenes by controlling unwanted reflections and deepening colors.
