Underdrawing
Underdrawing is a preparatory drawing done on a painting ground before paint is applied, for example, an imprimatura or an underpainting. Underdrawing was used extensively by 15th century painters like Jan van Eyck and Rogier van der Weyden. These artists "underdrew" with a brush, using hatching strokes for shading, using water-based black paint, before underpainting and overpainting with oils. Cennino D'Andrea Cennini (14th century most likely) describes a different type of underdrawing, made with graded tones rather than hatching, for egg tempera. In some cases, underdrawing can be clearly visualized using infrared reflectography because carbon black pigments absorb infrared light, whereas opaque pigments such as lead white are transparent with infrared light. Underdrawing in many works, for example, the ''Annunciation'' (van Eyck, Washington) or the ''Arnolfini Portrait'', reveals that artists made alterations, sometimes radical ones, to their compositions. The underdrawing ...

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700  nanometers (430  THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ...

Imprimatura
In painting, imprimatura is an initial stain of color painted on a ground. It provides a painter with a transparent, toned ground, which will allow light falling onto the painting to reflect through the paint layers. The term itself stems from the Italian and literally means "first paint layer". Its use as an underpainting layer can be dated back to the guilds and workshops during the Middle Ages; however, it came into standard use by painters during the Renaissance, particularly in Italy. The imprimatura not only provides an overall tonal optical unity in a painting but is also useful in the initial stages of the work, since it helps the painter establish value relations from dark to light. It is most useful in the classical approach of indirect painting, where the drawing and underpainting are established ahead of time and allowed to dry. The successive layers of color are then applied in transparent glaze or semi-transparent layers. Care is taken not to cover the imprimatura c ...

Underpainting
In art, an underpainting is an initial layer of paint applied to a ground, which serves as a base for subsequent layers of paint. Underpaintings are often monochromatic and help to define color values for later painting. Underpainting gets its name because it is painting that is intended to be painted over (see overpainting) in a system of working in layers. There are several different types of underpainting, such as veneda, verdaccio, morellone, imprimatura and grisaille.''Underpaint.'' In: The different types have different colourings. Grisaille is plain grey. Verdaccio is a grey tending towards yellow or green that brings out more luminous tones. While imprimatura uses earth tones. Underpainting has several advantages over working from a plain canvass. The neutral colours of the underpaint will not distract if they are not completely covered. It also aids the painter in getting a correct tone. Comparing colours to a white background is very different from the colouring of the f ...

Pentimento
A pentimento (plural pentimenti), in painting, is "the presence or emergence of earlier images, forms, or strokes that have been changed and painted over". The word is , from the verb , meaning 'to repent'. Significance Pentimenti may show that a composition originally had an element, for example, a head or a hand, in a slightly different place, or that an element no longer in the final painting was originally planned. The changes may have been done in the underdrawing of the painting, or by the visible layers of paint differing from the underdrawing, or by the first painted treatment of the element having been over-painted. Some pentimenti have always been visible on the final painting with careful inspection; others are revealed by the increasing transparency that some paint acquires after several centuries. Others, especially in the underdrawing, can only be seen with modern methods such as X-rays and infrared reflectography and photographs. These are able to record photogr ...

Edvard Munch
Edvard Munch ( , ; 12 December 1863 – 23 January 1944) was a Norwegian painter. His best known work, ''The Scream'' (1893), has become one of Western art's most iconic images. His childhood was overshadowed by illness, bereavement and the dread of inheriting a mental condition that ran in the family. Studying at the Royal School of Art and Design in Kristiania (today's Oslo), Munch began to live a bohemian life under the influence of the nihilist Hans Jæger, who urged him to paint his own emotional and psychological state (' soul painting'). From this emerged his distinctive style. Travel brought new influences and outlets. In Paris, he learned much from Paul Gauguin, Vincent van Gogh and Henri de Toulouse-Lautrec, especially their use of color. In Berlin, he met the Swedish dramatist August Strindberg, whom he painted, as he embarked on a major series of paintings he would later call ''The Frieze of Life'', depicting a series of deeply-felt themes such as love, anxiety, je ...

Madonna (Munch)
''Madonna'' is the usual title given to several versions of a composition by the Norway, Norwegian Expressionism, expressionist painter Edvard Munch showing a bare-breasted half-length female figure created between 1892 and 1895 using oil paint on canvas. He also produced versions in Printmaking, print form.Bischoff, Ulrich''Edvard Munch: 1863-1944'' p. 42, Taschen, 2000, , 9783822859711 The version owned by the Munch Museum of Oslo was stolen in 2004 but recovered two years later. Two other versions are owned by the National Gallery of Norway and the Kunsthalle Hamburg. Another one is owned by businessman Nelson Blitz, and one was bought in 1999 by Steven A. Cohen. The lithographic print of the composition is distinguished by a decorative border depicting wriggling sperm, with a fetus-like figure in its bottom left corner. The 1893 version of the painting had a frame with similar decoration, but it was later removed and lost. The print also exists in a number of different ver ...

Arnolfini Portrait
''The Arnolfini Portrait'' (or ''The Arnolfini Wedding'', ''The Arnolfini Marriage'', the ''Portrait of Giovanni Arnolfini and his Wife'', or other titles) is a 1434 oil painting on oak panel by the Early Netherlandish painter Jan van Eyck. It forms a full-length double portrait, believed to depict the Italian merchant Giovanni di Nicolao Arnolfini and his wife, presumably in their residence at the Flemish city of Bruges. It is considered one of the most original and complex paintings in Western art, because of its beauty, complex iconography, geometric orthogonal perspective, and expansion of the picture space with the use of a mirror. According to Ernst Gombrich "in its own way it was as new and revolutionary as Donatello's or Masaccio's work in Italy. A simple corner of the real world had suddenly been fixed on to a panel as if by magic... For the first time in history the artist became the perfect eye-witness in the truest sense of the term". The portrait has been conside ...

Annunciation (van Eyck, Washington)
''The Annunciation'' is an oil painting by the Early Netherlandish master Jan van Eyck, from around 1434–1436. The panel is housed in the National Gallery of Art, in Washington D.C. It was originally on panel but has been transferred to canvas. It is thought that it was the left (inner) wing of a triptych; there has been no sighting of the other wings since before 1817. The annunciation is a highly complex work, whose iconography is still debated by art historians. It was bought by the Tsar of Russia for the Hermitage Museum, but was sold by Stalin's government in 1930. The picture depicts the Annunciation by the Archangel Gabriel to the Virgin Mary that she will bear the son of God (Luke 1:26-38). The inscription shows his words: ''AVE GRÃ. PLENA'' or "Hail, full of grace...". She modestly draws back and responds, ''ECCE ANCILLA DÑI'' or "Behold the handmaiden of the Lord". The words appear upside down because they are directed to God and are therefore inscribed w ...

Egg Tempera
Tempera (), also known as egg tempera, is a permanent, fast-drying painting medium consisting of colored pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. Tempera also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint. Etymology The term ''tempera'' is derived from the Italian ''dipingere a tempera'' ("paint in distemper"), from the Late Latin ''distemperare'' ("mix thoroughly"). History Tempera painting has been found on early Egyptian sarcophagus decorations. Many of the Fayum mummy portraits use tempera, sometimes in combina ...

Carbon Black
Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal and coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content. However, carbon black can be used as a model compound for diesel soot to better understand how diesel soot behaves under various reaction conditions as carbon black and diesel soot have some similar properties such as particle sizes, densities, and copolymer adsorption abilities that contribute to them having similar behaviours under various reactions such as oxidation experiments ...

Drawing
Drawing is a form of visual art in which an artist uses instruments to mark paper or other two-dimensional surface. Drawing instruments include graphite pencils, pen and ink, various kinds of paints, inked brushes, colored pencils, crayons, charcoal, chalk, pastels, erasers, markers, styluses, and metals (such as silverpoint). Digital drawing is the act of drawing on graphics software in a computer. Common methods of digital drawing include a stylus or finger on a touchscreen device, stylus- or finger-to-touchpad, or in some cases, a mouse. There are many digital art programs and devices. A drawing instrument releases a small amount of material onto a surface, leaving a visible mark. The most common support for drawing is paper, although other materials, such as cardboard, wood, plastic, leather, canvas, and board, have been used. Temporary drawings may be made on a blackboard or whiteboard. Drawing has been a popular and fundamental means of public expression throu ...
