Line art
In photography, a line image is primarily understood to be a negative or positive photo with only pure black and white sections without any gray gradations. Contrast is the halftone image .
In conventional chemotechnical photography, line films , so-called technical papers ( see also: document paper , document film ) and hard-working developers , who divide the gradation, are used for the desired production of line images . In the printing industry, they played a major role in the production of clichés ( see also screening ).
In electronic image processing , line art - like many other things - can be created in most graphics programs with a simple click of the mouse.
