ABSTRACT
Almost every sketch in this book shows a light source and its resultant depth of field. The light source is indicated with the symbol of a glowing sun or circle and the depth of field through graphic illustration of receding planes, i.e., the use of the FGD, MGD, and BGD. Sharper focus will occur on the center of interest (usually human figures) when the amount of light falling on the figures is more or less intense (lit by the sun, the moon or artificial light). The type of lens used to focus on the subject will also make a difference, whether it's a wide-angle lens for sharper focus or a normal lens for average sharpness.
