Perspective drawings will utilize all methods listed here except

A. keeping objects in the background smaller than images in the foreground.

B. having a value change from background to foreground.

C. using a vertical line to establish where the sky and ground meet.

D. using a vanishing point to guide the orthogonal lines.

C. using a vertical line to establish where the sky and ground meet.

The correct answer is C. using a vertical line to establish where the sky and ground meet.

To determine which method is not utilized in perspective drawings, we need to examine each option and understand how it relates to the concept of perspective.

A. Keeping objects in the background smaller than images in the foreground: This is a fundamental principle of perspective drawing, known as size diminution. Objects that are farther away from the viewer appear smaller, creating a sense of depth. Therefore, this method is typically utilized in perspective drawings.

B. Having a value change from background to foreground: Value changes, or variations in light and dark, contribute to the illusion of depth and form in a perspective drawing. By using lighter values in the background and darker values in the foreground, an artist can create a sense of depth and three-dimensionality.

C. Using a vertical line to establish where the sky and ground meet: This technique is known as a horizon line. It serves as a visual reference point for determining the height of objects and their relative position within the scene. The use of a horizontal line does not restrict the horizon to a particular point, but rather establishes a reference plane.

D. Using a vanishing point to guide the orthogonal lines: Vanishing points are essential in perspective drawing, as they determine the convergence of parallel lines in a scene. Orthogonal lines are lines that recede into space and converge toward the vanishing point. By utilizing vanishing points and orthogonal lines, artists can create the illusion of depth and a realistic portrayal of space.

Therefore, among the given options, the method not typically utilized in perspective drawings is:

C. Using a vertical line to establish where the sky and ground meet.

This is because perspective drawings use horizontal lines (horizon lines) to establish the relationship between the sky and ground, rather than vertical lines.
