Florida Video Production

Traditionally the most favoured colour on the screen is blue. Also, earlier films used to be more sensitive to this colour as a result of which the shots use to come out better. Yet with the advanced software any colour can be used and all channels can be used. Everything said, a green colour screen is always good for a video. The film and television industry usually prefer a green or a blue screen against other colour tone. However it has to be ensured that the screen material which is used for the shot is not glossy as it will reflect light and this in turn will affect the edges of the foreground and spill the colour on the subject. One of biggest challenges we face while shooting with the best of cameras and developing them into quality production is the lighting aspect. With advanced software and technologies, the task of managing the technical side by placing the keyed figures in a sequence is now easy. However the one aspect which needs to be kept in mind for a seamless production is how to deal with the green light. There are some simple steps as to how to go about it while shooting on the green screen effect. While making a video production for a motion picture which requires the skill to shoot against a green, chroma or blue background it takes more than just a good lighting. To start with we need to visualize how the project will look like. For example if the film is about an apartment interior or a cocktail party, then the lighting needs to be according to the interior and even the camera needs to be placed at an appropriate height so that the footage can cover everything. The more the planning is in place, the better will be the shot. Also the subject needs to be at a considerable distance from the screen, almost 10 feet. This will help to separate the subject from the background. Hence the lines will be more defined and clear around the subject. A slight background light may be good to adjust with the green background which will counter effect the green light. The camera can also be set to the un sharpen mode. This will avoid compressing the input and producing slightly bit mapped and jagged edges. Un-sharping the camera will remove these problems. Also, even before the shot is taken, the camera needs to be rolled for a few seconds so that the footage which will be used is sharper and it is easier the separate the subject and the background once the camera rolls with the subject. While following these steps we also need to keep in mind that the chroma key background is lit uniformly which also includes the floor in case of a full shot. So the stage, background and the subject should be in sync so that uneven levels of chroma do not affect the footage. The reason why we need to be so careful with the background is that the light meters do not work effectively for a green screen. So its essential that we detect the hot spots and see how the luna and chrome levels look through a vectorscope and make the necessary corrections.
