Miracle of Green Screen

By Phillip Guye

Green Screen is really a shooting method used to bring one's creativity to actuality by placing an actor or subject in the foreground of a solid color backdrop screen. One of the main colors utilized is green because it is easy to work with and not as likely to clash with the foreground colors. This is why the word Green Screen is employed to identify this type of media. We all watch the magic of Green Screen or chroma key technologies everyday whenever we view the weather report on the daily news.

Measures found in making the Green Screen effects are: 1) Filming the actor or subject matter in the foreground of the chroma key screen. 2) Once the film is finished, it is shifted towards the editing room where post production is performed by eliminating the green background and replacing the empty area with the preferred background images. An example is in the motion picture Spiderman in which he's jumping between high buildings. 3) Throughout shooting of the first set of films, it is necessary to make use of correct lights to avoid shadows as well as to properly define the image outline. 4) Correct camera angles and distance is important for realism.

Other uses of Green Screen technological know-how over and above movie creating are: 1) Television production like news programs and action based Television shows. 2) Web advertising and marketing 3) Instructional videos such as teaching people how to fly an airplane or helping them get over their fears. 4) Shooting amazing action scenes without causing injuries or putting the actors at risk. 5) Improving still photography to create an amazing picture. 6) Making mtvs. 7) Chroma key allows for images to be added or removed from the film during the editing procedure.

Green Screen technologies bridges the distance between reality and illusions, giving film producers a chance to utilize their creative abilities to film impossible scenes. Advantages of Chroma key Coupled with Reality Set Technology: 1) Cost effective through the elimination of the expensive cost associated with location shooting such as: travel, gear transportation, extra film crew, cameras and lighting equipment, and other kinds of production tools required for filming. 2) Removes the studio's need to purchase expensive stock footage that occasionally doesn't provide what exactly is needed for a truly convincing set. The studio can purchase a relatively inexpensive 30 second film clip that may allow them to create a Reality set library that can be used again on other assignments. 3) Utilizing the Reality sets are more convenient than actual location filming that are limited by substantial costs, distance, time, weather disorders, remote location, as well as other production constraints. 4) Access to restricted places are overcome by utilizing chroma key technologies and Reality sets. A few illustrations are filming inside the Airport, the White House, or other places in which access is confined or limited. 5) Variety with a collection of Reality sets where the producers have diverse capabilities to very easily make changes, add, or delete locations. 6) Credibility is given to the producer while showing to brand new customers what's achievable to make using Green Screen technology and Reality sets. This technological know-how will save filming time through the elimination of the need for changing camera perspectives during filming. The camera angles are easily added during the post film production.

Is Green Screen technology confined only to movie studios with large budgets? The response to this question is absolutely no. This kind of technologies can be done at home. All that is needed are purchases of: a Green Screen kit, a Reality Set video, movie editing software program, and good imagination. Almost all of this products could be ordered via the internet. When you watch a film with incredible action or special effects you can say to yourself, I know how that was done. If you have a video clip or photograph you want to enhance or wish to earn a little extra cash in your own home, consider purchasing Green Screen technology.
