Green Screen Studios is an inexpensive video and film making system in which two frames are melded into one It is also ordinarily called Chroma key or infrequently color keying A prominent use is in TV weather circulars where the weather person looks to be standing in front of a huge graphic display What happens in reality is that the weather person stands in front of a blank Green Screen Studios Different graphic displays are then digitally added to the blank green portions to complete the illusion
Green is a preferred color because it is so different from human skin color that good separation is attained It's also the color to which digital cameras are most sensitive The other available color blue is less beneficial because it's a common color in both male and female clothing and requires brighter lighting Plenty of the more modern Star Wars flicks make intensive use of color keying techniques Green Screen Studios is also far cheaper than having your characters or props in front of an actual projection or TV screen
