CLOWN DANCES CIRCUS
Clowns have a varied tradition with significant variations in costume and performance. The most recognisable modern clown character is the Auguste or "red clown" type, with outlandish costumes featuring distinctive makeup, colourful wigs, exaggerated footwear, and colourful clothing. Their entertainment style is generally designed to entertain large audiences. Modern clowns are strongly associated with the tradition of the circus clown, which developed out of earlier comedic roles in theatre or Varieté shows during the 19th to mid 20th centuries. Many circus clowns have become well known and are a key circus act in their own right. The first mainstream clown role was portrayed by Joseph Grimaldi (who also created the traditional whiteface make-up design). In the early 1800s, he expanded the role of Clown in the harlequinade that formed part of British pantomimes, notably at the Theatre Royal, Drury Lane and the Sadler's Wells and Covent Garden theatres. He became so dominant on the London comic stage that harlequinade Clowns became known as "Joey", and both the nickname and Grimaldi's whiteface make-up design were, and still are, used by other types of clowns.
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.
