Chroma key compositing or green screen is a process for compositing two images or frames together wherein a green color is removed, exposing yet another image right behind it. This method is likewise referred to as color keying and often uses a specific shade of blue or green. These colors are classified as the furthest away from skin tone that irrespective of ethnic background, are very different contrasts of pink. As indicated by Wikipedia, green is currently applied as a background a lot more than any other color because image sensors in digital cameras usually are most sensitive to green. The marvel happens in the video editing software program as it looks for the particular shade of green and replaces it with the desired background.
The purity of the green screen color is yet another critical issue. If the green screen does not have purity of color, the completed matte will forfeit fine-edge detail like hair. Be sure to use materials as well as paints that are specifically made for green screen shots. While it helps to use colored lights or gels, be aware that they don’t sparkle on the talent as this is going to add serious green spill issues during compositing. Once the green screen lighting is set correctly, its lights could be turned off as well as the lights for the talent switched on. This is to make sure that the talent’s light will not ruin the green screen and that the talent will be lit for the planned setting they are going to be composited into.
Numerous green screen shots are part of a match move sequence in which the green screen layer has to be motion tracked during compositing in order to move it with the background. Tracking markers are put on the green screen. The color of the tracking markers isn’t significant as they can be easily keyed, painted, or rot scoped out, yet their shape and size is very important.
When shooting green screens with video, the first rule would be to switch off the video camera’s edge sharpening attribute. All camcorders have this function, called sharpness or detail or some other name, which is designed to make the photo appear sharper than the digital camera actually captures. The dilemma is that this sharpening adds edge artifacts which would significantly degrade the composite. The picture can be sharpened during compositing. Combining these lower color sampling cameras with the normal image compression that all modern cameras now use creates a photo which produces very poor quality composites.
In selecting the perfect Los Angeles green screen studio you have to be certain that the color is completely uniform as well as the surface completely flat. The screen likewise has to have the suitable measurements. It is recommended that you go through every single shot you plan and then measure the screen area so you have the proper measurements. Make allowance for a little additional in case you would like to dilate or frame the shot more than you had imagined. Study the area on each side of the screen to ensure that there is adequate room to position your lights. Ultimately, get the maximum possible space between your characters or props and the screen itself. This will make the job of lighting easier.
