Tone Curve Video Effect

The tone curve is used to brighten or darken tones in your image and is combined with the image histogram. An image histogram is a graphical representation of the tonal distribution in a digital image. It plots the number of pixels for each tonal value. By looking at the histogram for a specific image, a viewer will be able to judge the entire tonal distribution at a glance.
