Color correction is the use of color filters and brightness adjustments to make an image more eye catching. This can be done by the use of color gels and color filters which changes the intensity of the colors and rendering specific colors such as neutral colors, this method is known as gray balance, neutral balance, or white balance.
As the colors in an image range from a very wide spectrum of light and colors, any image can be altered to give a different look by changing the shades of light and color, creating filtered effects. Color correction aims to change the perceptual visual quality of the image which literally means to make the image more eye catching. This can be done in many ways, color correction does more than just adjust the color of an image, it also plays with the lighting of the image for special effects, like adding light or rays of sunshine in the background of an image to bring focus to the foreground of the image.
It is normally used by clients for product advertisements to give clothing wear and accessories a more striking look. Other uses for color correction may include car advertisements to showcase different colored cars using a single image or special effects adjustments to use the lighting to bring a single point of the image to the center of attention.
