Step 1: Understanding the Question:
The question asks about the number of sections an image is divided into when applying the "Rule of Thirds."
Step 2: Detailed Explanation:
The Rule of Thirds is a fundamental principle of composition in visual arts like painting, photography, and design. The guideline proposes that an image should be imagined as divided into nine equal parts by two equally spaced horizontal lines and two equally spaced vertical lines. Important compositional elements should be placed along these lines or their intersections. This creates more tension, energy, and interest in the composition than simply centering the subject. The grid of two horizontal and two vertical lines creates a 3x3 matrix, resulting in 9 equal parts.
Step 3: Final Answer:
The Rule of Thirds divides an image into 9 parts.
