The color correction artist is responsible for the finest color process and usually involves two components: video color correction and photo color correction. Footage taken from film is typically in a very compressed format that contains the highest dynamic range possible. This is the range where the camera is capable of capturing the lightest and deepest portion of an object without losing too much detail. This provides the colorist with the greatest freedom from which to apply color grade to achieve the best end result.
Video color correction generally involves removing red eye, blurring of edges and gradation of colors for a natural look in all scenes. It is done through editing and arrangement of objects within the shot to create harmony and true white. With the introduction of full digital video cameras, color correction has become much easier because the footage can be manipulated virtually in real time. This is accomplished using software such as Adobe Photoshop. There are many advantages to digital editing. The primary advantage is that it allows for precise manipulation of colors and contrast, which can be done without having to rely on an expert color grade. цветокоррекция видео
Video color correction is also done during post production. Colorists are able to manipulate images through corrections of hue, chromatic aberration, vignetting and brightness. After the process is complete, colorists must make sure that the final product is pleasing to the eye and that it holds up to the standards of the scene in which it was created. To accomplish this, the colorists must work with a wide variety of tools including hue wheels, wavelets, curves, masks, and curves.
There are four primary methods of video color correction, namely the curve, mask, curve blend and the wavelet grade. Hues and Vibrance can be manipulated using these methods. Hue wheel technology, developed in the 1950’s by photographer Lorraine Rothman, has become the most common grade used today. Other types of grade are also in use, including hue-based grading with its proprietary algorithm, and chroma keying, which correct colors by the chroma value of the outer portion of an object.
There are two ways to correct colors: masking and curve blending. Masking uses thin concentric circles while curve blending creates and exaggerates shadows. The technique you use is entirely dependent on the type of image you are trying to correct. In order to obtain a correct white balance, the contrast must be equal on both sides. The contrast can be either subtle or extreme. If the contrast is not correct, your footage will look unsightly and even shaky.
When working with video color correction, it’s crucial to understand that your monitor’s display will not match the colors you see in your monitors. This is because monitors are different sizes and the pixels are sized differently. Be sure to test the hue levels you are working with on a piece of cloth to make sure they are correctly displaying the color you have chosen. If not, you can be sure that you will not get the results you are expecting, and you will need to go back to the drawing board.
