Artifacts
Artifacts are distortions of an image either produced by the CCD, the optical system or compression algorithms such as JPEG.

The examples on this page were shot with my Canon 1DS MK II using auto white balance. They were converted from RAW to TIFF using each RAW converter's default color and exposure choices.

Although the MX2900 boasts higher resolution of 2.16 megapixels (effective) I'm still not convinced that it has any benefit over the lesser resolution CCD's of the Coolpix 950 or Oly C2000Z.
Artifacts
Artifacts simply refer to misinterpreted information from a JPEG or other compressed image. This misinterpretation will cause negative impact or distortions of an image e.g. color faults or line faults.

Artifacts - Distortions that often occur due to compressing or resizing an image.
ASA - Measure of film speed.
Aspect Ratio - The ratio of length to width. Most common image ratio is 4:3, although one may run into 3:2 quite often also.
ARTIFACTS - Sometimes spelled "artefacts" - Picture degradations that occur as a result of image-processing tasks, such as compressing an image which can result in an increase in digital "noise".
Artifacts
Digital image anomalies caused by the image sensor, optics or internal image processing of the camera.
Artifacts - Visual defects found in digital images.
Aspect Ratio - The ratio of width to height in photographic prints such as 3.5 x 5 inches or 5 x 7 inches.
Artifacts refer to distortions within the image as a result of image compression or interpolation. Artifacts can be seen as light halos around dark areas of an image or as 'blockiness' of a highlight area of an image.
The same artifacts as with the original set of reprints. The colors in the photos make the picture look sooooo fake, as though it had been printed on a deskjet printer! I'm not sure how do describe it but they really consistently look like crap!!! ...
The ghosting artifacts question relates to movement within the context of the images. People in the scene invariably move over the sequence of three shots and can be a real pain in the posterior.
quantization artifacts
Generally refers to features introduced in an image when the data used to render that image is converted to a data format capable of displaying fewer colors than the original.
Two, sharpening artifacts. Perhaps you've seen those little halos around some edges within your photo. That's because point-and-shoot cameras typically have the sharpness setting too high.
JPEG compression artifacts blend well into photographs with detailed non-uniform textures, allowing higher compression ratios.
Full quality (Q = 100), filesize 83261 B.
High quality (Q = 50), filesize 15138 B.
If any undesired artifacts remain in the mask, they can simply be painted over with the Brush set to the Normal Blend Mode. A white brush is used to eliminate undesired dark areas and a black brush is used to eliminate undesired white areas.
Things, such as dirt and dust, in the solution can cause artifacts on the film. Before equipment is used for mixing and measuring chemicals, you should clean it thoroughly.
The problem with in-camera sharpening is that it increases the visibility of jaggies and can increase the visibility of other image artifacts.
Adjustments made to high-bit data display fewer artifacts, but, whether significant or insignificant, there are artifacts nonetheless. Tweak more, and you continue to lose values and encounter rounding errors.
This is a really fun and powerful technique, perhaps too powerful and often giving images full of artifacts or with an unnatural look after the tone mapping step (halo artifacts are the most common).
An obvious one is potential motion artifacts from the differing capture intervals. Pixim has spent a great deal of time and effort creating imaging algorithms in their chipset to eliminate or at least minimize these issues.
With low light levels indoors, photos taken with both types of cameras can be susceptible to granularity or artifacts, however most users don't notice the effects - and many software applications exist that can reduce the artifacts, ...
One also often hears that working in Adobe RGB can promote more banding and other artifacts than can sRGB.
JPEG compression degrades image quality and can even introduce artifacts into your image.
Cons - teleconverters magnify all defects of a lens (noise, artifacts, lack of sharpness, etc.), so they must be used on a high-quality lens that has better resolution than your sensor; you will lose some resolution and contrast with a 1.
It is not well suited to non-photographic images due to compression artifacts that become readily apparent in line drawings or artwork and text with straight lines or sharp contrasting edges.
Think of how a museum cares for its artifacts and other treasures. Display and storage temperature, humidity and light remain within specific parameters and touching the exhibits is usually forbidden.
Noise - this is the appearance of unwanted color artifacts in digital images, and is particularly visible in solid blocks of colour such as blue skies or dark shadows.
Image noise is extraneous visible artifacts that degrades image quality. Luminance (grayscale) noise makes the image look grainy. Chroma (color) noise is usually visible as colored artifacts in the image.
Interpolation quality of the generic printer drivers is horrible and results in severe artifacts, clearly noticeable as jagged lines in the diagonal patterns of the image.

This is the jargon or informal name for digital artifacts found in raster images. These star-line lines appear where there should be a smooth straight line or curve.
Recently, I returned from a trip to the south coast of New Britain in Papua New Guinea, and in reviewing the photos, I found some of my more compelling images were of the indigenous people, the World War II artifacts and the landscape.
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.
High values make it possible to compensate for more complex distortions but can lead to artifacts and wrong matching in case moving objects are present in the scene (in this case the photos can be distorted to draw together the pictures of a moving ...
Place a number of similar artifacts in a room and the one that adheres to the Golden Ratio is the one most people will choose as being the most pleasing.

With your camera safely mounted on your tripod, you can dial in the lowest ISO sensitivity thus preserving sharpness and reducing noise artifacts in longer exposures.
The image on the left is an original image with a little dark midtones, some jpg artifacts with noise and too pronounced skin details.
The Digital Camera Enhancer corrects the midtones, adds saturation and soften the skin.

Flare has two possible effects- a haze-like lack of contrast across the image or visible artifacts called flare patterns.
First it's more efficient, meaning smaller files for similar qualty, second it's capable of lossless compression, meaning no loss of quality or generation of artifacts.

When the compression is that high, the uncompressed image will have "artifacts" in it. That is, stray pixels that don't match what is around them because the un-compressing didn't guess very well as to what the picture use to look like.

Offers variable degrees of compression: Higher compression rates result in smaller file sizes but also increase compression artifacts. Basically the compression is based on the reduction of the number of colors.

When you want to print extra extra large, RAW file format gives you more room to maneuver since there are no JPEG artifacts due to in-camera compression.
