Ever WOnder Why Its a GREEN Screen not Red, Yellow or Purple?!?

So I just wondered one day about the Green screen used to shoot
digital shots and movies and weather forecasts etc....
Don't YOU wonder why GREEN not any other colour of the Rainbow or spectrum?

GREEN is Least like our skin tone and the process uses
a technique called, "Chroma Key,"
which is the mixing of two images or frames together, in which a colour
(or a small color range) from one image is removed (or made transparent),
revealing another image behind it. BLUE is also used!

So as you should have figured if the person in front of a green screen
wears any piece of clothing green, that section of him will disappear.

If you want to know more about this process go read up HERE.

Not many people knew that filmmakers were already using special effects in the 1930s.

;Cuts of filmstrips edited and glued into montage/dissolve sequences.

Chromakey lighting is darn hard to light simply bcos the background has to be lighted 2 stops over than the normal exposure. so, you can imagine how films like 300 or even spiderman did it; precise lighting and a lot of rehearsals and blocking for camera and lighting as well as the actors....painful.

The most difficult effect to do? Creating water, fire, elements in film. To create "The Day after Tomorrow" where the floods and cold wind swept into the country...i think it took easily a yr or more to create the water element effect..for e.g.
