TV mode, short for Time Value, is a camera exposure setting more commonly known as shutter priority mode. In this mode, the photographer selects the desired shutter speed, and the camera automatically adjusts the aperture to achieve the correct exposure.
Photographers use TV mode to control motion in their images, such as freezing fast action or creating intentional motion blur. Understanding and using TV mode allows for creative control over movement, resulting in dynamic and expressive photographic effects.
