By Phillip Guye

Hollywood manages to transport moviegoers to different places be it real or normal. With today's sophisticated 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 restricted to only our imaginations. Also, creatures like monsters, angels, and beasts are brought to life with the help 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 2 pictures together. A solid background color is utilised so that another image can be transposed in front of the main picture. More frequently than not, green is the color used for this reason although blue is also generally used. Green is more favored among filmmakers because image sensors in cameras are sensitive to it. Green camera channels have less noise and can make the most clean masks. Also, the color green is commonly used as it doesn't have to be illuminated much, in comparison to other colors. This makes the green screen the ideal background of different productions from weather reports to giant budget Hollywood films.

However , there are some things to remember when using green screen Hollywood technology. Good production equipment like 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 critical to have all of the right gear when filming something that requires the Chroma Key technique.

Green screen Hollywood technology is also used to solve lots of filmmakers and photographers' issues. One vital use of the chroma key screen is that it permits the user to dump the need to find a real 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 don't exist anymore in this era.

Green screen Hollywood technology is principally used by pros. Except for being a typical tool employed in movies, it is also used for mag shoots, TV adverts, and studio photography. This is how shocking photographs and visual spectacles are made available to anyone who would desire something special for movies and photographs. When used the best way, green screens can help produce great pictures only the imagination can cook up. This is precisely why the green screen is one of the most trustworthy and helpful film making and photography tool there is.
