Chromatic aberration

Chromatic Aberration in a Single Lens Chromatic aberration or "color fringing" is caused by the camera lens not focusing different wavelengths of light onto the exact same focal plane (the focal length for different wavelengths is different) and/or ...

If you have ever looked through cheap children's binoculars the effect of chromatic aberrations will be all too familiar to you. This 'purple fringing' can sometimes be found on digital cameras as well.

Chromatic aberrations are reduced by using elements made of different varieties of glass.

Chromatic aberration Sensor effects: Chromatic aberration in each CCD cell (microlenses) Digital noise in dark areas Image processing and interpolation artifacts (almost all CCDs require considerable processing inside the camera) ...

Chromatic aberration Moderate to high chromatic aberration. The Kodak Z650's chromatic aberration is moderate at wide angle and high at telephoto focal lengths, showing about 6-8 bright pixels of coloration.

Chromatic aberration: The inability of a lens to bring light from the same subject plane but of different wavelengths, that is, of different colors, to a common plane of image or focus.

Chromatic aberration A lens aberration producing an overall blurred image; the inability of a lens to bring all wavelengths of light (especially red and blue) into the same plane of focus; ...

Chromatic aberration and purple fringing are two distortion effects that can negatively affect photographs. There are a couple of things you can do to minimize these effects. Read More » Universal 58mm White Balance lens cap Get Latest Price ...

Chromatic Aberration - Purple fringing that occurs along the edges of of backlit subjects such as plants, people, and buildings.

Chromatic aberration The inability of a lens to bring all light wavelengths (particularly red & blue) into the same plane of focus, thus causing overall blur. Usually found in regular large-aperture telephoto and super-telephoto lenses.

Chromatic Aberrations Also known as "purple fringing". It occurs from an optical point of view, and it depends on how you shoot and if your careful or not.

Chromatic Aberration The inability of a lens to focus different colours on the same focal plane. Appearing as a 'colour fringe' around objects, especially at the edges of the photograph.

Chromatic Aberration: Purple fringing that occurs because the image sensor doesn't capture the different colors (wave lengths) on the same focal plane through the lens. Can be caused by the lens optics. CMOS Image Sensor: ...

Chromatic Aberration A fringing effect around the edges, which is caused by lens not focusing correctly. CIFF ...

Chromatic Aberration In digital imaging most often seen as unwanted purplish lines along edges separating dark and light areas. CIFF ...

chromatic aberration: Also known as color fringing, this problem is caused when the camera lens do not focus the different wavelengths of light onto the exact same focal plane.

Chromatic Aberration. 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.

Chromatic Aberration - 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.

Chromatic aberration. A common lens flaw which results in loss of sharpness and also in colour fringing - white light having coloured halos (commonly green or purple) around the edges.

Chromatic Aberration: In photographic or lithographic process lens, the result of the unwanted dispersion of light so that colors of the white light spectrum are focused on slightly different distances on a single plane.

Chromatic aberration An optical defect of a lens which causes different colours or wave lengths of light to be focused at different distances from the lens. It is seen as colour fringes or halos along edges and around every point in the image.

(Chromatic aberration is corrected). Top of Page ASA American Standards Association; (see ISO). Top of Page B (Bulb) At the B setting, the shutter remains open as long as the shutter release button remains fully depressed. Top of Page Bracketing ...

The lens used in a color enlarger must be free of chromatic aberration; that is, it must be a color-corrected lens.

Chromatic aberration or Axial chromatic aberration - different wavelengths of light coming into focus in front of and behind the film plane, resulting in points of light exhibiting a rainbow-like halo and reduction in sharpness, ...

APO (apochromat) lenses are corrected for chromatic aberration. This allows light of all three primary colors, red, blue, and green, to a common point of focus.

"APO" elements (UD, SUD, CaF2, LD, SLD, ED etc.) improve contrast and sharpness by reducing chromatic aberration (color defects) that usually occur in tele lenses.

Optical flaws which are present in small amounts in all photographic lenses; made up of chromatic aberration, spherical aberration, curvature of field, distortion, etc.

It did a great job of correcting the consequences of lens defects such as barrel and pincushion distortion, chromatic aberration, vignetting and blur, but there was no way I could justify buying it.

A special design of lens that is highly corrected to avoid chromatic aberration by bringing the three blue, red and green wavelengths to one point of focus rather than the usual blue and green of an achromatic lens.

New features in this release include a redesigned and more powerful Lens Correction tool enabling correction of barrel and pin-cushion distortion, as well as chromatic aberration and vignetting.

Apochromat A lens corrected for chromatic aberration in all three primary colours. Search SWPP and BPPA Information provided by: SWPP BPPA More Photographic Terms ...

The drawback is a loss in dynamic range of the image and the dreaded purple fringing (sometimes erroneously referred to as "Chromatic Aberrations") of overexposed portions of the image.

If the photographer is the proper distance from his subject, he can minimize possible light and chromatic aberrations.

Optical aberrations occur when points of the image do not translate back onto single points after passing through the lens, causing image blurring, reduced contrast or misalignment of colors (chromatic aberration).

-Achromatic - lens system that has been corrected for chromatic aberration. -Acid - chemical substance with a pH value below 7.

Technically, a lens distortion that's caused by limitations of optics is an aberration, but usually that term is reserved for defects such as chromatic aberration (where colors focus at different points), ...

The Lens Correction filter is the best choice if additional corrections need to be made to the image (i.e., barrel distortion, pincushion distortion, vignetting, perspective, or chromatic aberration) Reminders and General Considerations ...

That’s as far as I go if I plan on working the image in PS. Otherwise I might make curves adjustments, sharpening and noise adjustments. Occasionally I run into vignetting or chromatic aberrations that benefit from the lens adjustment tab but ...

The chromatic aberration for two wavelengths is corrected for objectives of this type. Usually an objective of this type is corrected to a wavelength below 500nm and above 600nm. Furthermore, the sine condition for one wavelength is met.

I don't know what's causing this, although I suspect it's either an alignment issue with the scanner sensor, or else it's some chromatic aberration in the scanner optics. Either way, it's distressing, because it's clearly a Bad Thing.

Unless it’s blatantly obvious, I don’t comment much about vignetting, chromatic aberrations, coma, and other things that consume some reviewers. The final criterion is does the lens provide the results I desire?
