Perspective drawings will utilize all methods listed here except

(1 point)

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

having a value change from background to foreground.

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

using a vanishing point to guide the orthogonal lines,

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

The correct answer is:

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

To find the answer to this question, we need to understand the purpose of each method listed and determine which one is not used in perspective drawings. Let's break down each method:

1. Keeping objects in the background smaller than images in the foreground: This is a fundamental principle of perspective drawing. It helps create the illusion of depth by depicting objects farther away as smaller than those closer to the viewer. Perspective drawings indeed utilize this method.

2. Having a value change from background to foreground: Value refers to the darkness or lightness of a color. In perspective drawings, value changes from the background to the foreground help create depth and provide a sense of distance. Therefore, this method is also used in perspective drawing.

3. Using a vertical line to establish where the sky and ground meet: This method, known as the horizon line, is crucial in perspective drawing. It sets a reference point for the viewer and helps create the illusion of depth. Thus, this method is used in perspective drawings.

4. Using a vanishing point to guide the orthogonal lines: Vanishing points are points on the horizon line where parallel lines appear to converge. They play a key role in creating accurate representations of three-dimensional space in perspective drawing. Therefore, this method is definitely used in perspective drawings.

Based on the explanations above, the method that is not used in perspective drawings is "using a vertical line to establish where the sky and ground meet."
