In 1-point perspective, what two elements are identified to create depth?

• A. Focal length and aperture
• B. Color palette and temperature
• C. Horizon line and vanishing point
• D. Camera position

Answer: (C)

Depth in 1-point perspective comes from two elements: the horizon line and a single vanishing point on that line. The horizon line marks the viewer’s eye level. Parallel lines in the scene—like the edges of a road, tracks, or buildings—converge toward the vanishing point on that horizon. As objects recede, their edges move toward the vanishing point and they appear smaller, creating the sense of depth on a flat drawing. The other options relate to photography, mood, or camera position, but they don’t define how depth is constructed in 1-point perspective.
