The greater the bias toward the left in the graph, thedarker the image. The greater the bias toward the right, thebrighter the image.If the image is too dark, adjust the exposure compensation to apositive value. Similarly, adjust the exposure compensation to anegative value if the image is too bright (p. 56).Using the ViewfinderSample HistogramsBalanced ImageDark Image Bright Image
