Camaïeu (also called en camaïeu) is a technique that employs two or three tints of a single color, other than gray, to create a monochromatic image without regard to local or realistic color. When a picture is monochromatically rendered in gray, it is called grisaille; when in yellow, cirage.[1]
The term is also applied to monochrome painting in enamels. This technique uses a buildup of white enamel to create highlights and light areas. However, instead of using a black background, as in grisaille, transparent enamel is laid in first, beneath the whites. This technique is frequently used on snuffboxes, watches and medallions.
Camaïeu can also refer, following the French usage, to chiaroscuro woodcut prints that imitate highlighted drawing on tinted paper. However, the correct term in English for these is chiaroscuro woodcuts.
This French word once was synonymous with cameo, but its meaning became restricted in the early eighteenth century.[2]
Camaïeu is also a registered trademark of a manufacturer.
Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
