SCP ANTI CONTAMINATION SUIT
The SCP Foundation is a fictional secret organization documented by the collaborative writing wiki project of the same name. Within the website's shared universe, the SCP Foundation is responsible for capturing and containing various paranormal, supernatural, and other mysterious phenomena unexplained by mainstream science (referred to as anomalies or SCPs), while also keeping their existence hidden from the rest of global human society. The real-world website is community-based and includes elements of many genres such as horror, science fiction, and urban fantasy. On the SCP Wiki, the majority of works consist of SCP files (short for "Special Containment Procedures"), which are confidential reports that document an SCP object and the means of keeping it contained. The website also contains thousands of "Foundation Tales", which are short stories featuring various characters and settings in the SCP universe. The wiki's literary works have been praised for their ability to convey horror through a quasi-scientific and academic writing style, as well as for their high standards of quality.
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.
