ISO 800 represents a sensitivity setting on a camera’s sensor. A higher ISO value, such as 800, allows the sensor to capture more light. For instance, if a scene is dimly lit and the camera’s meter suggests underexposure at a lower ISO, increasing the ISO to 800 can brighten the image to an acceptable level.
Employing this particular ISO setting offers a balance between image brightness and noise levels. It is particularly beneficial in environments where additional lighting is unavailable or impractical. Historically, this setting provided a significant advantage for capturing usable footage in situations previously deemed too dark for video recording with acceptable quality. Modern cameras have improved noise performance, extending the utility of this and similar ISO values.
