Edit Picture

A well-exposed picture has a histogram with different elevations spread from

left to right. In contrast, a picture which is underexposed or overexposed has no

elevations or only very flat elevations in the left and/or right areas. To correct

such a picture, you can move the lines accordingly until they achieve the eleva-

tions or you can have it done automatically. The hue values then cover the en-
