Resources for Synthetic Aperture Color Finesse
The Synthetic Aperture Color Finesse plug-in included with After Effects includes excellent color-correction tools. Synthetic Aperture provides
tutorials and additional information about using Color Finesse on
their website .
Color Finesse installs its documentation in the plug-in’s subfolder in the Plug-ins folder. After Effects CC and CS6 include Synthetic Aperture Color
Finesse 3. (See Plug-ins.)
Color models and color spaces
A color model is a way of describing color using numbers so that computers can operate on them. The color model used within After Effects is the
RGB color model, in which each color is described in terms of amounts of red, green, and blue light added together to make the color. Other color
models include CMYK, HSB, YUV, and XYZ.
A color space is a variant of a color model. A color space is distinguished by a gamut (range of colors), a set of primary colors (primaries), a white
point, and a tone response. For example, within the RGB color model are several color spaces, including—in decreasing order of gamut size—
ProPhoto RGB, Adobe RGB, sRGB IEC61966-2.1, and Apple RGB. Although each of these color spaces defines color using the same three axes
(R, G, and B), their gamuts and tone response curves are different.
Though many devices use red, green, and blue components to record or express color, the components have different characteristics—for
example, blue for one camera is not exactly the same as blue for another camera. Each device that records or expresses color has its own color
space. When an image moves from one device to another, image colors may look different because each device interprets the RGB values in its
own color space.
Color management uses color profiles to convert colors from one color space to another, so colors look the same from one device to another.
