We therefore either need a bigger sensor to receive more information from lower light levels (which will be an investment in new hardware) or we can try to increase the light levels in the scene to allow more information to get to the sensor. What causes digital noise is low light levels and not enough ‘information’ hitting the sensor. It is true that the bigger (and more expensive) the sensor, the more light it can capture from darker settings. There wasn’t information in the light presented to the sensor therefore meaning the sensor does its best to represent the light it received. This ‘guess’ by the sensor is the resulting grain/noise. With digital footage, you are exposing light to a computer sensor that then reads and captures that light to a digital image as part of a video file.īecause a sensor is neither black nor white, it needs to fill in the missing information with something. If there is not enough light then the negative stays dark. With traditional film, the negative is exposed to light through the lens and the image is imprinted on the film. The exposure was incorrect at the point of capture.

The reason for both black on film and noise on digital footage is the same though.

In traditional film, you would not see grain/noise and instead would just see black.

It comes from a combination of your hardware set up and the shooting environment for your shoot.
