perspective
Let's put things in perspective - a point of view that shows the relationship between one thing and another. The word os used for objects and scenes depicted so that they appear to the eye to have the appropriate relationship and proportion to everything else in the painting. If a a barn is depicted in the painting, the cows abd sheep gazing near it will be proportionally smaller than the barn. As they paint, artists imagine converging lines invisible to the viewer of the paiting.
