The image may be printed to a size different from the negative or transparency. Without an enlarger, only a contact print would be possible, and large images would require large size negatives and hence very large cameras. Local contrast and density of various parts of the print can be easily controlled.
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.
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 ...
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.
A raster image is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. [1] Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats. The printing and prepress industries know raster graphics as contones (from continuous tones).
Contact print of a photo film cut in pieces, used for reviewing and selecting images for the final print. Photo by Paolo Monti, 1975. Contact printing is a simple and inexpensive process. Its simplicity avails itself to those who may want to try darkroom processing without buying an enlarger.
