The variation in tone from black to white.
TONAL GRADATION Photographers often concentrate on the density and detail of highlights and shadows when they should actually be considering the most important or middle tones of the negative.
Gradation setting
The E-420's gradation setting produces images in low or high keys, it does so by both modifying the tone curve as well as the exposure.
GRADATION - (1) An image's tonal contrast range. (2) The range of light and dark tones in a subject that a film is capable of showing (i.e. how a film reproduces contrast).
Gradations: Color gradations are colors that appear to change from one to another with smooth, seamless transitions.
gradation
gradual change of tones from one shade to another.
grade
to determine a type, category for various papers and cloth.(Paper grade categories are bond, uncoated book, coated book, text, cover, board, and specialty).
Gradation
A smooth transition between black and white, one color and another, or color and no color.

Gradation: In photographic originals and lithographic reproductions, the range of tones from the brightest highlights to the deepest shadows.
-Gradation - tonal contrast range of an image.
-Grade - system of terms and numbers used to denote the contrast characteristics of black and white printing papers.
-Graduate - vessel used for measuring liquids.
Degradation, Image Quality Loss
Loss of image quality or Definition for any number of reasons including intentional ones. Quote: I don't like forced development and flashing.
Gradation employs a series of motifs patterned to relate to one another through a regular progression of steps. This may be a gradation of shape or color.
Gradation
As the name suggests, the smooth and gradual change from one colour or shade to another.
Grey Level ...
I like the gradation of light around the can, the way it goes almost to black but not quite.
The objects you can see at the bottom of the picture are lumps of coal.

From this starting point, zones are formed by:
Dividing the tonal gradation into eleven equal sections.
Refers to the gradations of light and dark that a digital camera can capture where details are neither washed out by light nor concealed by shadows.

Bleeding is a degradation of image quality caused by oversaturated pixel sensors and results in 'colors that run'.
Bleed
used in printing as a margin of error. The image size exceeds the print size so that there are no borders with full bleed ...
The degree to which gradations in colour are represented in a storage method. For example, a system which allows 256 different values of red will have higher colour resolution than one which only allows 8 different values.
with a cellulose acetate base (popular through the 1970s) is frequently subject to vinegar syndrome, redox blemishes, and tears, and even preservation standard silver halide film on a polyester base can be subject to silvering and degradation of the ...
The Zone System is an 11-step gradation of reality, from pure black to pure white, and each step equates to one full f-stop.
However, the issue with JPEG images is that they go through a series of actions, each of which induces a small amount of image degradation. This series of image degradations becomes cumulative.
HDR (high dynamic range) function to create one composite image with an extra-wide gradation range from three images with different exposures ...
The gradation of colors is jumpy. If we give 256 steps (8 bits) to each of the RGB colors that create the color palette, these colors can be mixed in 16.7 million ways (256 x 256 x 256) to create 16.7 million color choices.
75,79 Posterization is the technique of separating the tonal gradations of a photograph into clearly defined steps. In effect, a smooth slope is converted into a staircase.
There are so many fewer levels of tones (256 versus a RAW image's 65,536) that if you make any large adjustments to the image you may get banding, noticeable transitions in what should be smooth gradations.
In some cases, typically in high-contrast gradations, these new elements can be so smooth that various output devices (from monitors to printers) may have difficulty rendering them. A little noise often can be the cure.
Fence lines, brick walls, patterns in weaved fabric and other repeating pattern type content are all prone to moiré degradation when the pattern magnification is very small on the sensor.
A developer designed to compress the general contrast range in a negative without influencing gradation in the shadow and highlight areas.
In fact, most are near shore and can suffer visibility degradation from rain runoff or detritus stirred up by surge.
And it is logical that if we later load JPG and then save again the degradation goes of course further.
Right now I can tell you the most degradation will be probably in the first round - from the original to the first JPG.
TWO HORIZONS: Whether youre shooting at sunrise or sunset, the sky color at the point of the rising or setting sun takes on a gradation of warm tones at the horizon and bleeds into cobalt blue the higher you look.
1) They do not have a continuous spectrum, if you look at the spectrum of a standard light bulb or of the sun the spectrum is a very smooth color gradation from red to blue, as I mentioned above.
Indeed, the only way to avoid further degradation would be to scan it at a resolution approaching what the images here are actually presented at.
Posterization is the process of changing the tonal gradations in certain areas of an image.
Increasing the ISO is fine up to a point but you don’t want excessive digital noise and a degradation of the image.
Less noise means cleaner, more attractive shadows, better color and finer tonal gradations. As a general rule, sensors in the most recent cameras have much better noise characteristics than earlier cameras.
When I look at this particular image, I can begin to see minor degradation at 60-percent compression (most visible on the border of the blue shirt).
5 wavelenghts of wavefront error image degradation becomes quite noticable. At 0.75 and 1 wavelength of wavefront error, image degradation is very noticable.
Here the M9 performed magnificently, capturing images with outstanding detail, impressive gradation, and subtle color rendition on a par with the output of the latest professional DSLRs.
This plugin is designed for quick Google Map implemention with a list of the locations that are specified within the HTML It allows for as much graceful degradation as possible by having as much semantic HTML as it allows.
An image consisting of smooth gradations of color between adjacent elements, requiring an output device capable of displaying thousands or millions of colors at high resolution in order to prevent image artifacts.

Soft light awakens worlds of subtle hue and gradation and provides a gentle but pleasant modeling in both landscapes and portraits.
Banding
An artifact of color gradation in an image, when graduated colors break into larger blocks of a single color, reducing the "smooth" look of a proper gradation.
Artifact
Unwanted digital image degradation (file compression) caused by errors or limitations during capture or created while processing, storage or transport.
(see JPEG, Lossy) ...
I call iZoom "ethical digital zoom" because it is not made available at full image size - this would cause image degradation.
How much of dust and surface scratch on the lens front element is enough to cause visible image degradation? And how much will render my 1000$ lens useless?
The gradation of shade is fantastic, as are the rainbow-like swaths of color on the upper left portion of the image. Mar made a good decision to crop the clouds tightly, as this is the "main show" and needs no other reference point.
Film photography is an analog process so the gradations in tone could perhaps be smoother than those created by the digital photography process.
The JPEG process is a 'lossy' one, meaning that some data is removed, and color gradients are simplified, which may result in some image degradation based on the amount of compression you choose.
Fogging - degradation of a photograph caused by stray light leaking onto the film or sensor, or by faults in developing, usually resulting in white areas on the final (positive) image.
Used for Web graphics which require more then 256 colors, like photos, graphics with smooth gradations etc.
PICT
Native bitmap and object-oriented file format for the Apple Macintosh (comparable to WMF in Windows).
To avoid image degradation, only use a teleconverter on a prime lens. There will be no noticeable loss of sharpness with a 1.4x teleconverter and a F2.8 lens. A larger port or port extension will be needed to accommodate the teleconverter.
Grade, of paper. Classification of black and white photographic papers by the gradation they offer between black and white. Soft (Grade 1) paper gives a wider range of gray tones than Hard (Grade 3). See also Variable contrast paper.
Digital
Opposite of analogue. Digital information is made up of a limited number of gradations (e.g. 256 colours, 8 bit). The change from one digital element to the next is always 'step by step' and not continuous.
Lossy Compression A reduction of image file size by disposing of unneeded data, resulting in a slight degradation of image quality. Low Key Refers to an image distinguished by overall dark tones.
Lossy compression (JPEG is an example) can result in visible degradation of image quality, especially when saving the same image as a JPEG multiple times, because some image data is lost in each compression process.
Color Banding - The appearance of visible bands of colors that replace subtle gradations in order to accommodate a reduced palette.
Adds light cyan and light magenta inks to the four-colour system, giving better gradations and skin tones, and allowing you to optimize print quality based on a specific printing task. Seven-ink includes the addition of photo black (dye-based) inks.
Unlike with optical zoom, no further image data is captured as the camera is digitally zoomed so degradation in quality occurs. In general, digital zoom is simply a marketing ploy and can be largely ignored.
