BLOG QUESTION: GAIN IN VIDEOGRAPHY

What is gain in video? What is it used for? What are some risks using it?

Gain controls the light sensitivity of the camera. It is mainly used to brighten the low lit or dark videos. You want to use the least amount of gain when filming, because it creates noise (static) in your video. Lower gain results in less noise and a sharper image, while higher gain creates more noise, softening your image. Having a high grain can lessen your video quality, so you only want to use it at night (you should always try to adjust exposure through organic ways before turning up the gain).
