Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two or more images or video streams together based on colour hues ( chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion ...
Basics of image editing. Raster images are stored in a computer in the form of a grid of picture elements, or pixels. These pixels contain the image's color and brightness information. Image editors can change the pixels to enhance the image in many ways. The pixels can be changed as a group, or individually, by the sophisticated algorithms ...
Sodium vapor process aka "yellowscreen" method. The sodium vapor process (occasionally referred to as yellowscreen) is a photochemical film technique for combining actors and background footage.

The PPU's video memory layout allows choosing one subpalette for each 16×16 pixel area of the background. (A special video mode of the MMC5 mapper overrides this, assigning a subpalette to each 8×8-pixel tile.) Sprites have an additional set of four 3-color subpalettes (with color 0 being transparent in each) and every 8x8 or 8x16 pixels can ...
Adobe Ultra is a discontinued vector keying application, helping produce blue-screen / green-screen effects for video (although the background can actually be any color).

Parallax scrolling is a technique in computer graphics where background images move past the camera more slowly than foreground images, creating an illusion of depth in a 2D scene of distance. [1] The technique grew out of the multiplane camera technique used in traditional animation [ 2 ] since the 1930s.
