SEXY ELF CHRISTMAS
An elf (plural: elves) is a type of supernatural being in Germanic mythology and folklore. Reconstructing the early concept of an elf depends almost entirely on texts in Old English or relating to Norse mythology. Later evidence for elves appears in diverse sources such as medical texts, prayers, ballads, and folktales. Recent scholars have emphasised, in the words of Ármann Jakobsson, that the time has come to resist reviewing information about álfar en masse and trying to impose generalizations on a tradition of a thousand years. Legends of álfar may have been constantly changing and were perhaps always heterogeneous so it might be argued that any particular source will only reflect the state of affairs at one given time.
Chroma key compositing, or chroma keying, is a special effects / post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture and videogame industries. A color range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific color-related variants such as green screen, and blue screen – chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from most human skin colors. No part of the subject being filmed or photographed may duplicate the color used as the backing.
