Paper texture limits what can be done with the calotype process. This texture can be seen by holding a piece of copier paper up to the light: the way fibers clump in the paper making process causes a relatively low contrast pattern that may remind one of bushes growing on a hillside.
The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed for a shorter time or through transparent or semi-transparent objects appear grey, [1] while fully-exposed areas are black in the final print.
Negatives were once commonly made on a thin sheet of glass rather than a plastic film, and some of the earliest negatives were made on paper. [4] Transparent positive prints can be made by printing a negative onto special positive film, as is done to make traditional motion picture film prints for use in theaters.
Advertisement for Ansco Cyko photographic paper, 1922. Photographic paper is a paper coated with a light-sensitive chemical, used for making photographic prints.When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from ...
A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper. [1]

A traditional paper-cut illustration by Wilhelm Gross. Since the late 18th century, silhouette artists have also made small scenes cut from card and mounted on a contrasting background like the portraits. These pictures, known as "paper cuts", were often, but not necessarily, silhouette images. European paper cuts traditionally have differed ...
GIF animation of an Apollonian sphere packing with transparent background. Transparency in computer graphics is possible in a number of file formats.The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible.
