How wide the photo is, in degrees across its width. Phone main camera: about 65°. Sets how blur and eye-facet sizes map to pixels.

Photos hold no ultraviolet. 1 = UV estimated from the smoothest spectrum that matches each pixel (an assumption); 0 = no UV information (the UV receptor just follows brightness).

Darkens the scene and applies this animal's low-light gain and noise (engine rule, not a measured sensitivity).

Pit vipers sense infrared with separate pit organs, not their eyes. A photo has no temperature, so this optional overlay marks only the brightest areas as "warm". It never tints the eye's colour view. Off by default.
