How Green Screen Worked Before Computers

How Green Screen Worked Before Computers

http://tomscott.com – http://twitter.com/tomscott – For those of us who grew up in the age of CGI, green screen is just “a thing that computers do”. But how did effects like this work before the age of pixels? With the help of some suitably shiny graphics, here’s a quick summary.

Thank you to Matt Gray – http://mattg.co.uk – http://twitter.com/unnamedculprit – for sterling work getting the camera and lighting right!

    Yea easy on the “click the buttons and settings and the greenscreen is
    gone” pal. It takes a lot more work than that.

    How do you know so much interesting information? Your CS background alone
    must have taken mad years to accumulate, plus all this culturally relevant
    science/tech.

    So many IGNORANT comments saying that due to technology, there’s no
    remaining talent or jobs. There are PLENTY OF JOBS, TECHNOLOGY HAS OPENED A
    WHOLE REALM OF JOBS AND LIVES MORE THAN ANYTHING. If anything, it is UTERLY
    STUPID AND ABSOLUTELY RIDICULOUS to have needless amounts of jobs and
    wasted lives to do tasks that a computer programmer can do in 1 hour.

    overall!

    I am not sure if I understood everything that was going on… I kinda got
    the film one, but you lost me at the TV explanation. I think I need some
    more graphs and pictures to really get it XD
