The success of the picture depends entirely upon the exposure; very little can be done in development to correct errors in timing, and it is the shadows that must be considered in judging the exposure.

Where light falls on an object and is reflected back to the eye, we see a highlight; where it strikes at an angle and is reflected back other than directly to the eye we see halftones; where no direct light falls on the object we have shadows: and these highlights, halftones and shadows are modified by light reflected into them by other objects and by other parts of the same object.
