Other Explanations
Purple fringing is usually attributed to chromatic aberration as described above, although it is not clear that all purple fringing can be explained this way. Other attributed causes of purple fringing in digital photography include many hypothesized sensor effects:
- Digital noise in dark areas
- Image processing and interpolation artifacts (almost all CCDs and CMOS require considerable processing)
- Stray ultraviolet and/or infrared light
- Image bloom from overexposure of CCD sensor (not applied to CMOS)

Famous quotes containing the word explanations:
“Financiers are great mythomaniacs, their explanations and superstitions are those of primitive men; the world is a jungle to them. They perceive acutely that they are at the dawn of economic history.”
—Christina Stead (1902–1983)
“Young children constantly invent new explanations to account for complex processes. And since their inventions change from week to week, furnishing the “correct” explanation is not quite so important as conveying a willingness to discuss the subject. Become an “askable parent.””
—Ruth Formanek (20th century)
