How do you set up a camera and lens for use in low light conditions and or with infra red lighting?
An ND1 (Neutral Density) filter should be placed in front of the lens when setting the back focus of a Color camera for low light conditions. An ND3 (Neutral Density) filter should be placed in front of the lens when setting the back focus of a Mono camera for low light conditions.
In order to set the back focus of a Mono camera equipped with I/R illumination for low light circumstances, an IRP (Infra-Red Pass) filter should be placed in front of the lens.
