How Bayer Sensors Work

12/06/2012 7:24 AM Eastern

RED explains how a Bayer array sensor works which might help you in your creative approach to using your camera (Bayer sensors are how most cameras acquire their image).

They write, "Digital sensors capture images using arrays of light-gathering wells or 'photosites.' When the exposure starts, these are uncovered to collect photons of light; then, when the exposure ends, these are read as an electrical signal, quantified and stored as values in a digital file. To assess color, photosites typically also use filters to ensure that only one color is stored at a time. What makes Bayer sensors unique is how these color filters are arranged."
