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 (CAs) manifest as unwanted colour banding, especially around high contrast edges. They occur when a lens bends some colours of light more than others, resulting in disperison. Lenses are designed to minimise CAs.
Chroma
The color of an image element (pixel). Chroma is made up of saturation + hue values, but separate from the luminance value.
Chromatic Adaption
Adjustment to overall color shifts, like those produced by filters.

Chroma: How pure a hue is in relation to gray
Saturation: The degree of purity of a hue.
Intensity: The brightness or dullness of a hue. One may lower the intensity by adding white or black.
Chromatic Aberration A phenomenon in which light rays passing through a lens focus at different points, depending on their wavelength.
Chromatic Aberrations - Color distortions that are a result of failure to evenly focus the lens.
Chrominance - The difference between a color and a specified reference color having a specified chromaticity.

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.
Chroma - Refers to the purity of color. The less gray, white, or black a color has in it, the more pure and vivid it will appear. Sometimes this term is used interchangeably with saturation.
Chromatic Colors
The "colorful" colors like, red, green, blue, yellow, purple, etc.
Figure: The chromatic primaries of additive color mixing are red, green and blue.
Chromatic Color - A color with at least one hue available, with a visible level of color saturation.
Contact Image Sensor (CIS) - Used in smaller, low-cost scanners, a new type of image sensor that has limitations on resolution.
Chromatic Aberration
A fringing effect around the edges, which is caused by lens not focusing correctly.

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. 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.
Chroma. Color or hue.
Chromatic aberration. An image defect, often seen as green or purple fringing around the edges of an object, caused by a lens failing to focus all colors of a light source at the same point.
Chroma Key see Blue Process
Chromatic Adaptation
The eye's ability to compensate, after a few minutes, for variations - sometimes drastic ones - in the color of light sources so that everything appears normal.
Chromatic Aberration (CA)
Also known as color fringing or halos, is caused when a camera lens does not focus the different wavelengths of light onto the exact same focal plane.
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 attributes
those attributes associated with the spectral distribution of light.
chromaticity
a color specification that is indicated by dominant wavelength and purity.
Chromatic Aberrations, Fringing, & Flare
I did not notice any aberrations or fringing in the 100% crops of the photos that I took, and the photos pointing toward the sun did not have any significant flare. Well done, Panasonic! ...
-Chromatic aberration - inability of a lens to bring light from the same subject plane but of different wavelengths to a common plane of image or focus.
-Chromaticity - objective measurement of the color of an object or light source.
Chromatic Aberration
Also known as color fringing, chromatic aberration occurs when the collective color wavelengths of an image fail to focus on a common plane.
Chromatic aberration Edit
Chromatic aberrations are reduced by using elements made of different varieties of glass.
[edit] Chromadepth method and glasses
The Chromadepth procedure of American Paper Optics is based on the fact that with a prism colors are separated by varying degrees.
CHROMAKEY-An electronic special effect that combines two video sources into a composite picture, creating the illusion that the two sources are physically together.
Chromatic noise produces a more 'unnatural' appearance, and it's easier to reduce without compromising image sharpness than luminance noise.
Chromatic Aberration
This effect often occurs in digital cameras of two megapixels or more, using a long telephoto lens. It can be seen as a ring of purple color separating a dark area of a picture from a light area that surrounds it.
Chromatic Aberration
A fringe or outline of any color generated when the lens does not focus all light waves at the same focal point.
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.

chromatic aberrations
Every lens, to a greater or lesser extent, focuses the light of different wavelengths onto different focal planes and magnifies it differently.
chroma key says:
It depends on how you handle your camera with F shutter setup with ISO setting. it is really a matter of creativity and what you want to achieve in your photograph.
The Chromatic Aberrations Correction module, which is available for licensing, provides functions which automatically correct aberrations, minimizing the circle of confusion. It is the only available technology for completely automatic CA correction.
When Chroma conducts, there are ways to take advantage of his performance. Look for strong silhouettes offset against the color of the sky. The silhouette should have distinct shape and form unto itself.
The "Chroma" option of the LCH Editor though works quite well for controlling saturation.
Correct chromatic aberrations, vignetting, minor distortion.
Correct anything that was not fully handled in raw conversion.

I also tick "Reduce chromatic aberrations" and "Reduce noise".
Next, if you have any objects that were moving between your three shots, you will need to tick "Attempt to reduce ghosting artifacts", "Background movements.
Aberration Chromatic:
An optical image distortion conditional on the varying refraction of light rays of different wavelengths on a lens. Thus light rays of shorter wavelengths have longer focal distances than light rays of longer wavelengths.
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 ...
Chromatic aberration: The inability of a lens to bring light of different colors to a common point of focus.
Circle of confusion: Disks of light in the image produced by a lens from a point source of light.
"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.
YUV is a color model which uses two components to represent the color information, luma (the strength of the light per area) and the chrominance, or proportion of color (chroma), where the chrominance again consists of two components.
Both show some chromatic aberration, probably due to the TC as much as the lens. The Canon less is very well chromatically corrected and the mirror lens should have no intrinsic chromatic aberration. Though the Canon lens is at f4.
Many are cheap and poorly-made and can cause distortion, chromatic aberration, and other problems and are often quite soft, especially on the edges, as you've found.
I've recently found the aligning feature for image stacks is far superior in CS5 to the tonemapping software, as is the chromatic aberration removal in Adobe Camera Raw. So my workflow and overall IQ is improved over what it used to be.
A similar affect is called Chromatic Aberration. These effects are caused when you shoot a subject that is strongly back lit. All lenses can have this problem...
Many consumer grade lenses show a tendency for Chromatic Abberations (colored halos that are caused by light bending as it passes through the lens). The effect is similar as going through a prism.
Saturation, sometimes called chroma, is the strength or purity of the color. If you adjust saturation through its entire range, colors go from rich and vibrant to dark gray.
Reserve the strongest chroma for the center of interest and add a touch of its complement to make the surrounding color stand out more. Do not repeat the same color that appears in the background in the foreground.
A lens corrected for chromatic aberration (color fringing) at three wavelengths in the visible spectrum.
