This was the first project where we used the "change color" effect in Premiere Pro to lighten up the hand in the video. This allowed us to increase contrast and darken the blacks in the rest of the video, giving it a sharper tone overall.
Previously the problem was that even though we would have liked applying more contrast and black colors, it made the hand look very dark and ugly. But by adding the change color effect, selecting the darkest shades of the hand, increasing lightness and color by about 2 points each with minimal tolerance (ca. 2-5) and spread (ca. 1-2), the hand brightened up overall while looking just as realistic. This allowed us to apply more effects to the rest of the footage.
As a result, we added this step to our video editing procedure increasing our quality overall with a neglectable increase in editing and rendering time.
