Chromatic aberration
|
- Optical term, which refers to the distortion of an image as a result of a scattered focal point caused by a defect in a lens. a combination of lens can be used to correct this effect.
- Chromatic aberration. failure of a lens to focus all colours at the same point. the aberrations can be along the optical axis (longitudinal ca, or loca) or off-axis (lateral or transverse ca, tca).
- An optical defect of a lens which causes different colors or wave lengths of light to be focused at different distances from the lens. it is seen as color fringes or halos along edges and around every point in the image.
- Also known as the purple fringe effect. it is common in two megapixel and higher resolution digital cameras (especially those with long telephoto zoom lenses) when a dark area is surrounded by a highlight. along the edge between dark and light you will see a line or two of purple or violet colored pixels that shouldn`t be there.
- Also known as color fringing, chromatic aberration occurs when the collective color wavelengths of an image fail to focus on a common plane. the results of chromatic aberration are most noticeable around the edges of high-contrast images, especially toward the edges of the frame. chromatic aberration is most common on less expensive lenses, although even the best optics can occasionally display lower levels of chromatic aberration, under certain conditions.
- In terms of lens optics it is the failure of the lens to focus all colours (rgb) at the same point. it shows up as colour fringes in areas of the image where dark meet light (think edge of a building against the sky). it is more common in wide angle lenses, and those of inferior optics (kit lenses). it is correctable, to some degree, using photoshop, lightroom or software of your choice.
- Also known as purple fringing. it is fairly common in 2mp digital cameras and above, especially if they have long telephoto lenses. you can see it when a dark area is surrounded by a highlight. in between the dark and light, you may see a band of purple pixels that shouldn’t be there. there are ways of removing this which i have covered in the photoshop section.
- When a lens causes white light to be broken into various component colors with each focus at a different distance from the lens, commonly producing color fringe around a viewed image.

Aberración cromática, испанский
Хроматические аберрации, русский
- Один из видов аберраций в оптике. хроматическая аберрация обусловлена различиями в коэффициентах преломления для волн различной длины. в результате изображение получается менее четким (падает разрешающая способность) и контрастным. хроматическая аберрация наиболее сильно проявляется в телеобъективах. объективы, в которых устранена хроматическая аберрация, называются апохроматы и ахроматы.
- Проявление зависимости характеристик оптической системы от длины волны света.

- A term from optics that refers to anything affecting the fidelity of the image in regards to the original scene.
- A distortion of image quality or color rendition in a photographic image caused by optical limitations of the lens used for image capture. aberrations commonly show up in the form of halation around high-contrast portions of the image, or “smearing” of color toward the edges of the frame. aspheric lens surfaces and advanced lens coatings are often used in more expensive or complex lenses as a means of reducing aberrations. for more on this subject, see the explora article, “optical anomalies and lens corrections explained.”
- Any flaw introduced during the manufacturing or grinding of a spectacle lens that can result in image blur. it may be inherent in the lens design or may result from an error in processing.
