Artists use the trick of _____ to give the illusion of depth in a painting.

• A. convergence
• B. texture gradient
• C. binocular disparity
• D. accommodation

Answer: (B)

Verified step by step guidance

1. Identify the key concept being tested in the problem, which is the illusion of depth in a painting.
2. Understand that the term 'texture gradient' refers to a visual cue used by artists to create the perception of depth. As objects recede into the distance, their texture becomes finer and less detailed.
3. Consider the other options: 'convergence' refers to the inward movement of the eyes when focusing on a close object, 'binocular disparity' involves the slight difference in images between the two eyes, and 'accommodation' is the process by which the eye's lens changes shape to focus on near or far objects.
4. Recognize that 'texture gradient' is a monocular cue, meaning it can be perceived with one eye, and is commonly used in art to simulate depth.
5. Conclude that 'texture gradient' is the correct answer as it directly relates to the technique artists use to create the illusion of depth in a painting.
