5-1 ADVANCED PERSPECTIVE No.1 Roll-over perspective Here is a painting that utilizes a single vanishing point without unduly discomforting the eye. I call this roll-over perspective. My aim in this painting was to paint the total extent of the landscape beyond what the camera or the eye would see, and without moving the eye's cone of vision. As the landscape is essentially flat the illusion needed is one that combines (in the perspective mode) a plan view with an elevation. Also to make the transition as seamless as possible! Secondly the perspective scale must be such that the distance from tee to green should still appear at least 400 yds. Two essentials must be realised to understand how the illusion is completed.

First: the eye has a natural cone of vision wherein it can focus. This is usually about 30 degrees. Beyond this cone focus is lost - even though movement is discernable up to 160 degrees(wiggle your thumbs and see when they disappear). To look at my painting you will note I trick or force the eye to alter its cone of vision, when it really, is not necessary. It does not have to refocus to see the entire painting, but I make it believe it does. We are forced to look 'down' at the tee and 'up' at the green.The eye will refuse to do otherwise. Second: the perspective scale is distorted in that I
