CUPID VALENTINE’S DAY
In classical mythology, Cupid (Latin Cupīdō [kʊˈpiː.doː], meaning "desire") is the god of desire, erotic love, attraction and affection. He is often portrayed as the son of the love goddess Venus and the war god Mars. He is also known in Latin as Amor ("Love"). His Greek counterpart is Eros. Although Eros is generally portrayed as a slender winged youth in Classical Greek art, during the Hellenistic period, he was increasingly portrayed as a chubby boy. During this time, his iconography acquired the bow and arrow that represent his source of power: a person, or even a deity, who is shot by Cupid's arrow is filled with uncontrollable desire. In myths, Cupid is a minor character who serves mostly to set the plot in motion. He is a main character only in the tale of Cupid and Psyche, when wounded by his own weapons, he experiences the ordeal of love. Although other extended stories are not told about him, his tradition is rich in poetic themes and visual scenarios, such as "Love conquers all" and the retaliatory punishment or torture of Cupid.
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.
