Images captured from our video cameras are in color. Adjustments in contrast, color, sharpness, etc., should be made on these raw video images. They can actually be done at almost any step along the way, but VERY IMPORTANT, these adjustments should only be done once to an image.

Consult the Photoshop manual for information on using tools when description is not provided.
