JEFF THE KILLER
"Jeff the Killer" is a story accompanied by an image of the title character. In the story, a teenager named Jeff is on his way to school with his younger brother when they are attacked by a group of bullies. Jeff defends himself and his brother, and leaves the assailants lying in the street beaten, their hands and arms broken. After his brother claims he injured the bullies and is arrested, Jeff spends several days distraught, before going to a birthday party in the neighbourhood where he is attacked by the bullies again. Although he manages to kill all of the assailants, he is severely burned during the confrontation after being set on fire. During a stay at the hospital, Jeff realizes that he enjoys harming people, and goes insane. The night after he is discharged, he slices his face, leaving a scar in the shape of a smile, and cuts off his eyelids, so that he will never sleep. He then murders his parents and brother, whispering "go to sleep" while killing his sibling. He becomes a serial killer who sneaks into houses at night and whispers "go to sleep" to his victims before killing them.
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.
