Camera equipment has evolved through the years from the old pinhole cameras to the very sophisticated equipment of today. During this time there has been an ever increasing desire to produce photographic, videographic or cinematic special effects, while keeping cost effectiveness of the equipment and technique in mind.
Various camera techniques including chromakeying, luminous keying, and double exposures. These techniques involve the use of two cameras simultaneously, the images of which are combined into a single image. Alternatively, the seperate images can be shot with the same camera with the images combined into a single image.
Before now the equipment needed for these functions have been extremely complicated and expensive. These techniques were limited to those commercial production houses that had sufficient finances and trained personnel for expensive and complex equipment. What is needed in the industry is a simplified piece of equipment and methodology for carrying out these various filming techniques. The simplified method and equipment should be designed to be used by the amateur or beginning enthusiast, yet maintain the high quality of production experienced by the commercial production houses.
