What is the meaning of t for camera?

Answer 1

In Photography, "t" typically refers to the exposure time or shutter speed, which is the duration the camera's shutter remains open to allow light to hit the sensor. A longer exposure time (a higher "t" value) lets in more light, which can result in brighter images or capture motion blur, while a shorter exposure time captures sharp images of fast-moving subjects. It is a crucial element in achieving the desired exposure and artistic effect in an image.
