[keenoe] Sousou no Frieren - 01

This footage exhibits pronounced chromatic aberration—visible as color fringing and distortion—due to being captured with an old Zeiss Plan-Apochromat (circa 1930s). Since lenses like this lack distortion metadata, modern digital cameras are unable to compensate.

To restore the image, we employed a photochemical process: the original video was projected in reverse through the same lens onto physical film negative, effectively “undoing” the lens’ optical flaws. The resulting negative was then rescanned using a high-resolution modern film scanner (e.g., Lasergraphics Director 10K), yielding a cleaner image with minimized chromatic artifacts.

This hybrid analog-digital approach leverages the lens’s inherent characteristics to counteract its own distortions—a solution blending vintage optics with contemporary precision.
