Appendix A: TARGA 3000 Effects Guide
Color
Color correction in the TARGA 3000 is performed via a “Look-up Table.” This is also
known as curve based color correction. A graph represents the way in which input color
values are translated into output color values.
The color corrector allows you to perform fine adjustments to the colors of the image. The
curve defines the input to output transfer function of the color components. The default
for each color component is simply a straight line that runs in a diagonal as shown above.
This shows that all input values map to the identical output values, therefore no change is
made to the image.
Enable -- This check box must be selected in order for any color adjustments to be made.
Reset -- Resets the current curve to default.
Reset All -- Resets all curves to default.
