Checkerboard Pattern Image - High-Contrast Grid for Design & Testing #3557210 (License: Personal Use)

This image features a precise 6×6 grid of alternating black and white squares, forming a standard checkerboard pattern. The squares are uniformly sized and sharply defined, making it suitable for visual calibration, digital art reference, or as a neutral backdrop in presentations. Its symmetry and contrast support accessibility testing and optical experiments.

Used in web design as a placeholder or texture, in photography for focus/alignment checks, in computer vision for camera calibration, and in educational materials to demonstrate pattern recognition or perspective.
