Welcome to the world of Green Screen! Once the exclusive domain of Hollywood special effects artists, green screen imaging has expanded to include video, computers, and photography. There are many mysteries to the successful execution of a green screen composite and considerable confusion as to what a green screen composite is. Robert James Photography has been able to learn and efficiently execute all aspects of green screen and offers it to you and your clients. This is an exciting addition to the photography world, and we are at its forefront. Be one of the first to catch the Green Screen Phenomena!! It�s exciting and virtually limitless!
What is Green Screen?
Creating a green screen composite image starts with a subject that has been photographed in front of an evenly lit, bright, pure green background. The compositing process, whether photographic or electronic, replaces all the green in the picture with another image, known as the background plate.
Green screen composites can be made optically for still photos and digitally to computer images. Another term for Green Screen is Chroma-Key. Chroma-Key is a digital process only.
How does Chroma Key work?
The Chroma Key process is based on the Luminance key. In a luminance key, everything in the image over (or under) a set brightness level is "keyed" out and replaced by either another image, or a color from a color generator. (Think of a keyhole or a cookie-cutter. When we want to key people over a background image, problems arise because people and their clothing have a wide range of tones. Hair, shoes and shadow areas may be very dark, while eyes, skin highlights and shirt collars can approach 100% white. Those areas might key through along with the background. This is where fine-tuning comes in. We use the latest and fastest software to maintain even pictures and perfectly groomed edges. This allows for no green blotches to show up in prints.
What Lighting for is needed for Green Screen?
A considerable amount of mystery is usually attached to green screen lighting design. Also, a number of myths have been nurtured through the years, most of which are only half true. Myth Largest is the flat lighting myth. While it is true that the green screen must be lit evenly, this is not true for the talent or other foreground subjects. They may be lit as dramatically as you desire. The trick is in lighting the foreground without screwing up the background.
WHAT SIZES DO YOU OFFER?
We offer a variety of sizes. The most common size is 5x7. It is a great size, and fits into a common stock frame and people like displaying this size. We do offer 4x6 if there was a need or desire for a smaller size. They all come in a matted folder/folio sized for the picture.
