Image editor programs use a mathematical process called resampling to calculate new pixel values whose spacing is larger or smaller than the original pixel values. Images for Internet use are kept small, say 640 x 480 pixels, which would equal 0.3 megapixels.
The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest-neighbor interpolation. Other scaling methods below are better at preserving smooth contours in the image.
Photographic printing is the process of producing a final image on paper for viewing, using chemically sensitized paper. The paper is exposed to a photographic negative , a positive transparency (or slide ) , or a digital image file projected using an enlarger or digital exposure unit such as a LightJet or Minilab printer.
Tiled printing is a method that computer programs use to enable users to print images larger than a standard page. This method was popularized by a program called The Rasterbator. A tiled printing program overlays a grid on the printed image in which each cell (or tile) is the size of a printed page, and then prints each tile. A person can then ...
Art photography print types refers to the process and paper of how the photograph is printed and developed. C-Print / Chromogenic Print : A C-Print is the traditional way of printing using negatives or slides, an enlarger, and photographic paper—through a process of exposure and emulsive chemical layers.
An image scaled with nearest-neighbor scaling (left) and 2×SaI scaling (right) In computer graphics and digital imaging, image scaling refers to the resizing of a digital image. In video technology, the magnification of digital material is known as upscaling or resolution enhancement.
