Going a spot in the center of the bend adjusts the midtones, and going a spot within the base section associated with the bend adjusts the shadows. To darken highlights, go a spot close to the the top of bend downward. Moving a point either down or even the maps that are right Input value to a lowered production value, in addition to image darkens. To lighten the shadows, move a true point close to the base associated with bend upward. Going a point either up or even to the maps that are left reduced Input value to an increased production value, as well as the image lightens.
