Milkwalker is a cartoon character of a milk carton introduced by American dairy cooperative Darigold, Inc. as its company mascot in the mid-1980s. Due to its eerily disproportionate physical appearance, the character became a popular subject of creepypastas and trollpastas on Tumblr in December 2016. Milkwalker, an anthropomorphic milk carton, was originally created by Seattle-based dairy and agricultural co-op Darigold, Inc. as the mascot of the company and a public service announcement character that encourages children to remember their full name, address and telephone number in case of emergencies. On November 28th, 2016, over three decades after its introduction, various images of the obscure mascot began circulating online after it was highlighted by the Tumblr blog Heck-Yeah-Old-Tech (shown below).
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.
