Imagine
that you are sitting infront of a countyside scene. You are overwhelmed
with information, possible things to draw. In this situation, we can
use the visor to enclose the scene, to centre our interest in a precise
area.
In
any composition (be it a scenery, a still-life, etc), it is important
to find an interesting point.
The
visor will also help us to choose the format, the composition.
