Dodge or burn areas
Used to lighten or darken areas of the image, the Dodge tool and the Burn tool are based on a traditional
photographer’s technique for regulating exposure on specific areas of a print. Photographers hold back light to lighten
an area on the print (dodging) or increase the exposure to darken areas on a print (burning). The more you paint over
an area with the Dodge or Burn tool, the lighter or darker it becomes.
