Spherical Aberration
An optical imperfection caused by spherical lens curvature where peripheral rays focus closer to the lens than axial rays, reducing contrast.
Detailed Analysis & Visual Theory
Spherical Aberration represents an essential cornerstone of photographic expression, visual narrative, and technical mastery.
