Optical Low Pass Filters
RED continues to revolotionize the motion picture camera industry by providing users with more options than any other manufacturer to customize the build, functions, and look of their cameras.
The optical low pass filter (OLPF) controls the properties of the light that reaches the sensor, giving the cinematographer control over the image before the signal is processed. Options available include OLPF's designed to optimize image highlights, low light sensitivity, skin tones, infra red transmission, and underwater shooting. All RED optical low pass filters are designed to counteract moire artifacting.
