The original photograph depicts the shutter of a Canon EOS-1D Mark II.
This decorative texture does not depict the EOS 5D Mark IV used for the camera
body on this site and does not imply endorsement by the photographer or Canon.

Changes: cropped from the licensed 1280px Commons rendition, rotated 40 degrees,
cropped again to isolate the photographed blades, darkened and desaturated,
and compressed as a 420 x 280 WebP. No mirroring or generated texture was used.
The texture is split into two opposing animated curtains during capture.
