What Are Four Reasons for Color Correction?
- Use color correction to create a focal point in the frame. This type of color correction causes the edges of the picture to darken, while the main item or person lightens slightly, creating a focal point in the image. This type of color correction is known as spot color correction and can be used in place of camera effects. It is also known as creating a vignette, as the edges of the image gradually fade away. Vignettes can portray an individual's specific point of view or add interest to a boring area of the image, such as a large blank wall or lots of sky.
- Use color correction for relighting if you could not achieve the desired lighting on set, as there are many constraints to lighting a scene. This is used to punch the color on eyes or faces or to remove unwanted light in specific areas of the image.
Day to Night
- Use color correction to alter an image that was shot in the day to one that appears as a night scene. Shooting locations may only be available at specific times of the day, which may not match the actual circumstances of story. However color correction can be used to alter the lighting to change the time of day. This removes some shooting constraints, specifically on a very tight shooting schedule.
- Films are rarely shot in order. Therefore it is necessary to match the shots of film that appear in sequence, but were shot many days if not months apart. Color correction can alter the saturation, hue, light and density of light and color to match the shots so it appears to be one seamless shot. Color correction will first match the white and blacks between the shots before matching the tonal ranges.
