Most people think of perspective as a rigid concept that involves t-squares, rulers and mathematical calculations. In architecture and engineering, that holds true. However in painting, a gestural, expressive approach to perspective can create a wonderfully expressive quality that adds movement to your composition.
In order to use gesture to suggest perspective, you have to understand the overall concept of the type of perspective you are working with in a given situation. For example, the drawing above uses one point perspective to show the log laying in the field. One point perspective is a great compositional device in that it automatically draws you into the painting. But there is no need to break out the ruler and t-squares to draw the log. Simply establish the horizon line and vanishing point, and loosely pull the lines of the log back toward them after establishing the circle of the front plane that faces the viewer.
The sense of depth and space is further compounded by the use of atmospheric perspective. The contrast and detail is more pronounced in the foreground and less pronounced in the distance. This is done by comparing value relationships and creating subtle shifts in the values as they move into the background versus stronger contrast in the foreground. The background values are closer to one another and hence create softer edges, where the opposite is the case in the foreground. Additionally, small details such as the grass blades and highlights of sun on the log create the sense of detail in the foreground.
Understanding these concepts and applying them in a loose, painterly manner creates a realistic impression without becoming rigid or tight. This creates a more expressive result, which in turn makes a more personal statement.
