Stippling is the creation of a pattern simulating varying degrees of solidity or shading by using small dots. Such a pattern may occur in nature and these effects are frequently emulated by artists. Such a pattern may occur in nature and these effects are frequently emulated by artists.
An example of the mastery of coloured stipple engraving by Francesco Bartolozzi (1727–1815) Cupid Binding Aglaia to a Laurel, detail, after Angelica Kauffmann (1741–1807) Stipple engraving is a technique used to create tone in an intaglio print by distributing a pattern of dots of various sizes and densities across the image.
Coquille board, also known as stipple board, is a type of drawing paper with a pebbled texture. The grain is impressed into the uncoated paper during manufacture. [ 1 ] Used with a soft lithographic crayon or carbon pencil , coquille produces a shading effect similar to hand stippling in a fraction of the time. [ 2 ]
For example, when leaves alternate up a stem, one rotation of the spiral touches two leaves, so the pattern or ratio is 1/2. In hazel the ratio is 1/3; in apricot it is 2/5; in pear it is 3/8; in almond it is 5/13. [56] Animal behaviour can yield spirals; for example, acorn worms leave spiral fecal trails on the sea floor.

For example, in the Chauvet-Pont-d'Arc Cave (circa 30,000 BC), at least 13 different species have been identified. [2] In one prehistoric cave (circa 15,000 BC), there is a drawing of a mammoth with a darkened area where the heart should be. If this is indeed the intention of the illustration, it would be the world's first anatomical ...
Bioart is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes. Using scientific processes and practices such as biology and life science practices, microscopy , and biotechnology (including technologies such as genetic engineering , tissue culture , and cloning ) the artworks are ...

The Young Shepherd, engraving using stipple technique. Giulio Campagnola (Italian: [ˈdʒuːljo kampaɲˈɲɔːla]; c. 1482 – c. 1515) was an Italian engraver and painter, whose few, rare, [1] prints translated the rich Venetian Renaissance style of oil paintings of Giorgione and the early Titian into the medium of engraving; to further his exercises in gradations of tone, he also invented ...
