Optical Science vs. Creative Exploitation

Stray off-axis light reflects repeatedly between air-glass element boundaries. Each ghost mirror reflects the aperture stop geometry.

Optical Flaw Degrades contrast and creates veiling glare washing out shadows.

Artistic Intent Evokes warmth, organic cinematic texture, and golden-hour atmosphere.

Glass has wavelength-dependent refractive indices (dispersion), focusing blue light closer to the lens than red light.

Optical Flaw Color fringing along high-contrast silhouette edges.

Artistic Intent Gives vintage lenses their distinct painterly signature and separation.

Out-of-focus point sources trace the exact polygon of mechanical iris blades. Narrow apertures diffract light into sharp sunstars.

Even Blades (6, 8) Produce N spikes (opposite blades overlap).

Odd Blades (5, 7, 9) Produce 2N spikes (non-overlapping rays create vivid starbursts).
