WEREWOLF DARK FUR
In folklore, a werewolf[a] (Old English: werwulf, "man-wolf"), or occasionally lycanthrope /ˈlaɪkənˌθroʊp/ (Greek: λυκάνθρωπος lukánthrōpos, "wolf-person"), is a human with the ability to shapeshift into a wolf (or, especially in modern film, a therianthropic hybrid wolflike creature), either purposely or after being placed under a curse or affliction (often a bite or scratch from another werewolf) with the transformations occurring on the night of a full moon. Early sources for belief in this ability or affliction, called lycanthropy /laɪˈkænθrəpi/, are Petronius (27–66) and Gervase of Tilbury (1150–1228). The werewolf is a widespread concept in European folklore, existing in many variants, which are related by a common development of a Christian interpretation of underlying European folklore developed during the medieval period. From the early modern period, werewolf beliefs also spread to the New World with colonialism. Belief in werewolves developed in parallel to the belief in witches, in the course of the Late Middle Ages and the Early Modern period. Like the witchcraft trials as a whole, the trial of supposed werewolves emerged in what is now Switzerland (especially the Valais and Vaud) in the early 15th century and spread throughout Europe in the 16th, peaking in the 17th and subsiding by the 18th century.
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.
