Cone of Vision

It is important to be able to conceptualize a cone of vision. Understand how humans see an area. Where is the vision optimized and where are it's limits. This helps with understand distortion and perspective. Things converge to a point at different degrees. Geometry plays a major role in understanding the essential ideas that an artist has to know. When you are able to visualize the various fields of vision, you can quick draw precise camera angles.
