Green Screen Hollywood Technology - What it Consists of and How to Use It

Hollywood manages to transport moviegoers to different places be it real or ordinary. With today's advanced film making technologies, anyone can take a look at ancient Rome's grand coliseums, walk on the surface of Jupiter, and visit dimensions that was once limited to only our imaginations. Also, creatures such as monsters, angels, and beasts are brought to life with the aid of green screen Hollywood technology. But what exactly is green screen or "Chroma Key" technology? How does it work?

Green screen technology is the mixing of two images together. A solid background color is utilized so that another image can be transposed in front of the main picture. More often than not, green is the color used for this purpose although blue is also widely used. Green is more popular among filmmakers because image sensors in video cameras are sensitive to it. Green camera channels have less noise and can make the cleanest masks. Also, the color green is often used because it doesn't have to be illuminated much, as compared to other colors. This makes the green screen the ideal background of different productions from weather reports to big budget Hollywood flicks.

However, there are some things to keep in mind when using green screen Hollywood technology. Good production equipment such as lights and quality cameras should be used when using Chroma Key technology screens. Bad lighting can cause unsightly shadows and wrong shades on the screen. Therefore, it is imperative to have all the right equipment when filming something that requires the Chroma Key technique.

Green screen technology is also used to solve a lot of filmmakers and photographers' problems. One important use of the chroma key screen is that it allows the user to eliminate the need to find an actual background. Green screens allow filmmakers and photographers to be flexible. With green chroma key screen technology, any image can be added and used as the final background. This is how many Hollywood personalities end up in far flung regions of the universe or in ancient cities that no longer exist in this era.

Green screen Hollywood technology is mainly used by professionals. Aside from being a common tool used in movies, it is also used for magazine shoots, television ads, and studio photography. This is how stunning images and visual spectacles are made available to anyone who would want something special for movies and photographs. When used the right way, green screens can help produce great images only the imagination can cook up. This is precisely why the green screen is one of the most reliable and useful filmmaking and photography tool there is.
