The three primary colors are red, green, and blue. Color correction professionals are involved in manipulating the balance, saturation, and luminance of these three colors in the recorded image. Before the advent of digital imaging, an art director was responsible for choosing film of the correct ASA rating and color temperatures that complimented the shooting environment.
Daylight film would produce images that appeared normal if the shooting took place during the day. The results of using tungsten film under tungsten lighting also appeared normal. The art director’s ability to manipulate the image was limited. It was possible to create a blue cast on the film when tungsten film was used under daylight conditions; using daylight film under tungsten lighting resulted in an orange cast to the resulting film.
Computer Generated Imagery
In the early 1990s, the film was scanned to create a digital intermediate. This allowed for computer-generated visual effects to be wrought into the film footage. This proved to be a cumbersome and expensive process; as such, it was used primarily to effect shots.
With the rapid development of advanced technology, the cost of digital imaging fell. Unlike the old film process, digital color correction could manipulate the parts of the image that the colorists chose rather than change the color of the whole image.
Digital Imaging is Today’s Norm
Hi-tech digital video cameras allow the color balance to be set electronically. There are different digital formats in common use; depending on the choice of format, the image may or may not be manipulated. This is of little concern when the image is color balanced on the set, but many media projects are changed during post-production.
If you intend to create images that amaze your audience, many companies can ensure this happens.
Color correction can make a world of difference in the outcome of digital imaging. To see how Chromavision uses their professional services to turn your production needs into reality, visit http://www.chromavision.net. Follow us on twitter.
