Color is a fundamental part of photography as it conveys the idea in a photograph. Color correction is a must have for a consistent look in your photos. Color correction is, essentially, changing the original photo to make it look more truthful. With this technique, overall colors of a photograph are modified to make it look better and natural as if you are seeing it with your naked eyes.
Color correction includes removing or adding shadows, removing red eyes, adjusting luminance, hue and saturation and much more. Old photos that have lost their colors can also be improved with color correction.
