The digital photo workflow has three major creative phases: Composition and shooting Digital image processing Presentation (print, slideshow, Web gallery, etc.)
Bayer pattern
human eye can differentiate between many more shades of green than it can red or blue, which is not surprising when you consider the number of shades of green in nature.
A software trick called Bayer pattern demosaicing, or color interpolation, adds the missing RGB information using estimates garnered from the color information in neighboring pixels.

A demosaicing (also de-mosaicing, demosaicking or debayering) algorithm is a digital image process used to reconstruct a full color image from the incomplete color samples output from an image sensor overlaid with a color filter array (CFA). It is also known as CFA interpolation or color reconstruction.
Most modern digital cameras acquire images using a single image sensor overlaid with a CFA, so demosaicing is part of the processing pipeline required to render these images into a viewable format.
Many modern digital cameras can save images in a raw format allowing the user to demosaic them using software, rather than using the camera's built-in firmware.
