Pinxit (from Latin: 'one painted') is a stylized amendment added to the signature depiction of the name of the person responsible for a work of art, found conventionally in the Late Middle Ages and the Renaissance. It is sometimes abbreviated P, PIN, or PINX, as in some paintings by Raphael. The locution me pinxit is found on a 12th-century crucifix, not in a sense connected to individual authorship but rather as a more impersonal devotional statement, a "pious [formula] appropriate for liturgical gifts".

Its use by Duccio c. 1255–1260 – c. 1318–1319) on the Maestà in Siena Cathedral is seen as an "audacious" claim by the author, who asserts an individual status on a par with that of the city. By the Late Middle Ages in Venice and elsewhere pinxit (or other forms of pingere, in Gothic lettering) had become customary, and was often found on a cartellino, "any form of fictive paper carrying an inscription", established in Venice by the 1440s. Other verbs used to establish authorship include conjugations of facere ("to make"; fecit ("made by") was frequently used by Titian) or fingere ("to conceive"). (Full article...)

A house painter and decorator is a tradesperson responsible for the painting and decorating of buildings, and is also known as a decorator, or house painter. The purpose of painting is to improve the appearance of a building and to protect it from damage by water, corrosion, insects and mould. House painting can also be a form of artistic and/or cultural expression such as Ndebele house painting. (Full article...)

In painting, local color is the color of an object when seen under flat white light with no adjustment for form shadow or colors of light or secondary light sources. An example would be the assumption that an apple is "red" when it is actually dependent on the color of the light hitting it, color of objects around it, glossiness, and variations within the colors on the surface of the apple itself. Local color is learned in childhood to help simplify and make sense of the world. "The sky is blue", "grass is green", etc. when there are actually myriad variations in hue, chroma, within these areas. In order to represent objects realistically, painters must look beyond the simplifications of local color. Demonstrations of color constancy show how flawed local color assumptions can be when the light source has a color shift.

In contemporary sculpture local color is the original color of the raw material that remains unpainted in the completed work. (Full article...)

Incised painting is a technique used to decorate stone surfaces. First, a channel is scratched in the stone. Then, a thick paint or stucco plaster is laid across the surface. Last, the paint is scraped off the surface of the stone, leaving paint in the incision. This technique was used in decorating the Taj Mahal. (Full article...)

Genre painting (or petit genre) is the painting of genre art, which depicts aspects of everyday life by portraying ordinary people engaged in common activities. One common definition of a genre scene is that it shows figures to whom no identity can be attached either individually or collectively, thus distinguishing it from history paintings (also called grand genre) and portraits. A work would often be considered as a genre work even if it could be shown that the artist had used a known person—a member of his family, say—as a model. In this case it would depend on whether the work was likely to have been intended by the artist to be perceived as a portrait—sometimes a subjective question. The depictions can be realistic, imagined, or romanticized by the artist. Because of their familiar and frequently sentimental subject matter, genre paintings have often proven popular with the bourgeoisie, or middle class.

Genre subjects appear in many traditions of art. Painted decorations in ancient Egyptian tombs often depict banquets, recreation, and agrarian scenes, and Peiraikos is mentioned by Pliny the Elder as a Hellenistic panel painter of "low" subjects, such as survive in mosaic versions and provincial wall-paintings at Pompeii: "barbers' shops, cobblers' stalls, asses, eatables and similar subjects". Medieval illuminated manuscripts often illustrated scenes of everyday peasant life, especially in the Labours of the Months in the calendar section of books of hours, most famously the Très Riches Heures du Duc de Berry.

En plein air (pronounced [ɑ̃ plɛ.n‿ɛʁ]; French for 'outdoors'), or plein-air painting, is the act of painting outdoors.

This method contrasts with studio painting or academic rules that might create a predetermined look. The theory of 'En plein air' painting is credited to Pierre-Henri de Valenciennes (1750–1819), first expounded in a treatise titled Reflections and Advice to a Student on Painting, Particularly on Landscape (1800), where he developed the concept of landscape portraiture by which the artist paints directly onto canvas in situ within the landscape.

Paint Dancing is an American art and dance craze which involves both painting and dancing. Paint Dancers, using paint, brushes and paper, attend organized events dressed in ready-to-paint and dance clothing. The concept of combining movement and painting originated during the later part of the American and European Modern art period; however, Evangeline Welch of Shreveport, Louisiana has been credited with being the "brainchild" of Paint Dancing in the United States of America. This departure from traditional painting styles was often referred to as Action painting. Over the years, several variations of the art form have evolved, including an adaptation introduced by the Hippies during the Summer of Love, that integrated the art of body painting with dancing. One of the more recent introductions of Paint Dancing to American culture is being popularized by a grassroots movement created in 2006 by Seattle artist and activist Matt Jones. The phrases "paint dancing" and "paint dancer" and other variations were originally coined in 1996 by Gloria M. Buono, author, illustrator and publisher of The Painting Ballerina. (Full article...)

Boston Expressionism is an art movement marked by emotional directness, dark humor, social and spiritual themes, and a tendency toward figuration strong enough that Boston Figurative Expressionism is sometimes used as an alternate term to distinguish it from abstract expressionism, with which it overlapped.

Strongly influenced by German Expressionism and by the immigrant, and often Jewish, experience, the movement originated in Boston, Massachusetts, in the 1930s, continues in a third-wave form today, and flourished most markedly from the 1950s until the 1970s. (Full article...)

Historic paint analysis, or architectural paint research, is the scientific analysis of a broad range of architectural finishes, and is primarily used to determine the color and behavior of surface finishes at any given point in time. This helps us to understand the building's structural history and how its appearance has changed over time. Researchers may gather data for the history of the interior decoration of a building or room.

Historic paint analysis shares a common methodology with the conservation and restoration of paintings used to conserve and restore two- and three dimensional works of art. This involves the identification of components such as organic or inorganic pigments and dyes contained in the pigments. Historic paint analysis also identifies the pigments' media of suspension such as (water, oil, or latex and the paints' associated substrate. A variety of techniques are used to identify and analyze the pigment layers and finish exposure, including Finish Exposure, optical microscopy, fluorescent light microscopy, polarized light microscopy, and Fourier-transform infrared spectroscopy.

In the visual arts, style is a "... distinctive manner which permits the grouping of works into related categories" or "... any distinctive, and therefore recognizable, way in which an act is performed or an artifact made or ought to be performed and made". Style refers to the visual appearance of a work of art that relates to other works with similar aesthetic roots, by the same artist, or from the same period, training, location, "school", art movement or archaeological culture: "The notion of style has long been historian's principal mode of classifying works of art".

Style can be divided into the general style of a period, country or cultural group, group of artists or art movement, and the individual style of the artist within that group style. Divisions within both types of styles are often made, such as between "early", "middle" or "late". In some artists, such as Picasso for example, these divisions may be marked and easy to see; in others, they are more subtle. Style is seen as usually dynamic, in most periods always changing by a gradual process, though the speed of this varies greatly, from the very slow development in style typical of prehistoric art or Ancient Egyptian art to the rapid changes in Modern art styles. Style often develops in a series of jumps, with relatively sudden changes followed by periods of slower development n style typical of prehistoric art or Ancient Egyptian art to the rapid changes in Modern art styles. Style often develops in a series of jumps, with relatively sudden changes followed by periods of slower development. Additionally, external factors such as social, political, and technological changes often influence the evolution of artistic styles, shaping their direction and characteristics. The influence of cultural exchange and globalization has also played a significant role in the blending and transformation of styles, leading to new and innovative artistic expressions.

The ISCC–NBS System of Color Designation is a system for naming colors based on a set of 13 basic color terms and a small set of adjective modifiers. It was first established in the 1930s by a joint effort of the Inter-Society Color Council (ISCC), made up of delegates from various American trade organizations, and the National Bureau of Standards (NBS), a US government agency. As suggested in 1932 by the first chairman of the ISCC, the system's goal is to be "a means of designating colors in the United States Pharmacopoeia, in the National Formulary, and in general literature ... such designation to be sufficiently standardized as to be acceptable and usable by science, sufficiently broad to be appreciated and used by science, art, and industry, and sufficiently commonplace to be understood, at least in a general way, by the whole public." The system aims to provide a basis on which color definitions in fields from fashion and printing to botany and geology can be systematized and regularized, so that each industry need not invent its own incompatible color system.

In 1939, the system's approach was published in the Journal of Research of the National Bureau of Standards, and the ISCC formally approved the system, which consisted of a set of blocks within the color space defined by the Munsell color system as embodied by the Munsell Book of Color. Over the following decades, the ISCC–NBS system's boundaries were tweaked and its relation to various other color standards were defined, including for instance those for plastics, building materials, botany, paint, and soil.

In painting, a pentimento (Italian for 'repentance'; from the verb pentirsi, meaning 'to repent'; plural pentimenti) is "the presence or emergence of earlier images, forms, or strokes that have been changed and painted over". Sometimes the English form "pentiment" is used, especially in older sources. (Full article...)

The paint and sip industry is a set of experience-based businesses that hire professional artists to provide step-by-step instructions to reproduce a pre-selected work of art while they drink wine or other beverages. When class attendees finish, they get to keep their creations.

These classes typically focus on painting as a fun activity for relieving stress, rather than as a technical skill requiring practice like the classes at an atelier or an art school. Alcohol is used to reduce inhibitions and "overthinking" in order to make the creative process feel easier. (Full article...)

In visual art, mixed media describes artwork in which more than one medium or material has been employed.
Assemblages, collages, and sculpture are three common examples of art using different media. Materials used to create mixed media art include, but are not limited to, paint, cloth, paper, wood and found objects.

Mixed media art is distinguished from multimedia art which combines visual art with non-visual elements, such as recorded sound, literature, drama, dance, motion graphics, music, or interactivity. (Full article...)

Industrial paint robots have been used for decades in automotive paint applications.

Early paint robots were hydraulic versions, which are still in use today but are of inferior quality and safety to the latest electronic offerings. The newest robots are accurate and deliver results with uniform film builds and exact thicknesses. (Full article...)

The Boston school was a group of Boston-based painters active in the first three decades of the twentieth century. Often classified as American Impressionists, they had their own regional style, combining the painterliness of Impressionism with a more conservative approach to figure painting and a marked respect for the traditions of Western art history. Their preferred subject matter was genteel: portraits, picturesque landscapes, and young women posing in well-appointed interiors. Major influences included John Singer Sargent, Claude Monet, and Jan Vermeer. Key figures in the Boston school were Edmund C. Tarbell, Frank Weston Benson, and William McGregor Paxton, all of whom trained in Paris at the Académie Julian and later taught at the School of the Museum of Fine Arts. Their influence can still be seen in the work of some contemporary Boston-area artists. (Full article...)

A problem picture is a genre of art popular in late Victorian painting, characterised by the deliberately ambiguous depiction of a key moment in a narrative that can be interpreted in several different ways, or which portrays an unresolved dilemma. It has some relation to the problem play. The viewer of the picture is invited to speculate about several different possible explanations of the scene. The genre has much in common with that of book illustration, then at its most popular, but with the text belonging to the illustration omitted.

The genre began to emerge in the second half of the nineteenth century, along with the development of book illustrations that depicted "pregnant" moments in a narrative. One of the earliest problem pictures is John Everett Millais' Trust Me, which depicts an older man demanding that a young woman hand him a letter she has received. Either character might be uttering the words. The significance and content of the letter is left to the imagination. Their relationship is also unclear; in view of their ages, they might be a married couple, or a father and daughter. (Full article...)

Painterliness is a concept based on German: malerisch ('painterly'), a word popularized by Swiss art historian Heinrich Wölfflin (1864–1945) to help focus, enrich and standardize the terms being used by art historians of his time to characterize works of art.

A painting is said to be painterly when there are visible brushstrokes in the final work – the result of applying paint in a manner that is not entirely controlled, generally without closely following carefully drawn lines. Any painting media – oils, acrylics, watercolors, gouache, etc. – can produce either linear or painterly work. Some artists whose work could be characterized as painterly are Pierre Bonnard, Francis Bacon, Vincent van Gogh, Rembrandt, Renoir, John Singer Sargent, and Andrew Wyeth (his early watercolors). The Impressionists, Fauvists and the Abstract Expressionists tended strongly to be painterly. (Full article...)

Abstract art uses visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Abstract art, non-figurative art, non-objective art, and non-representational art are all closely related terms. They have similar, but perhaps not identical, meanings.

Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality. By the end of the 19th century many artists felt a need to create a new kind of art which would encompass the fundamental changes taking place in technology, science and philosophy. The sources from which individual artists drew their theoretical arguments were diverse, and reflected the social and intellectual preoccupations in all areas of Western culture at that time.

French standard sizes for oil paintings refers to a series of different sized canvases for use by artists. The sizes were fixed in the 19th century. Most artists—not only French—used this standard, as it was supported by the main suppliers of artist materials. Only some contemporary artist material suppliers continue to use these standards today, as most artists no longer differentiate canvas sizes by subject.

The main separation from size 0 (toile de 0) to size 120 (toile de 120) is divided in separate runs for faces/portraits (figure), landscapes (paysage), and marines (marine) which more or less keep the diagonal. That is, a figure 0 corresponds in height to a paysage 1 and a marine 2.
In modern times in the USA size is usually stated height by width, where as in this article it is width by height. (Full article...)

Architectural painting (also Architecture painting) is a form of genre painting where the predominant focus lies on architecture, including both outdoor and interior views. While architecture was present in many of the earliest paintings and illuminations, it was mainly used as background or to provide rhythm to a painting. In the Renaissance, architecture was used to emphasize the perspective and create a sense of depth, like in Masaccio's Holy Trinity from the 1420s.
In Western art, architectural painting as an independent genre developed in the 16th century in Flanders and the Netherlands, and reached its peak in 16th and 17th century Dutch painting. Later, it developed in a tool for Romantic paintings, with e.g. views of ruins becoming very popular. Closely related genres are architectural fantasies and trompe-l'oeils, especially illusionistic ceiling painting, and cityscapes. (Full article...)

A tondo (pl.: tondi or tondos) is a Renaissance term for a circular work of art, either a painting or a sculpture. The word derives from the Italian rotondo, "round". The term is usually not used in English for small round paintings, but only those over about 60 cm (two feet) in diameter, thus excluding many round portrait miniatures – for sculpture the threshold is rather lower.
A circular or oval relief sculpture is also called a roundel. The infrequently-encountered synonym rondo usually refers to the musical form. (Full article...)

A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion.

More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it. Examples include glue, adhesive and thickening. (Full article...)

An airbrush is a small, air-operated tool that atomizes and sprays various media, most often paint, but also ink, dye, and make-up. Spray painting developed from the airbrush and is considered to employ a type of airbrush. (Full article...)

Pen painting is a painting technique used by seventeenth-century artists from the Dutch Republic. First the artist grounds a canvas with white oil paint before drawing on it with blue India ink. The invention of the technique is commonly attributed to Willem van de Velde the Elder. (Full article...)

Fat over lean refers to the principle in oil painting of applying paint with a higher oil to pigment ratio ('fat') over paint with a lower oil to pigment ratio ('lean') to ensure a stable paint film, since it is believed that the paint with the higher oil content remains more flexible.
Oil paint dries at different rates due to the differing drying properties of the constituent pigment. However, everything else being equal, the higher the oil to pigment ratio, the longer the oil binder will take to oxidize, and the more flexible the paint film will be. Conversely, the lower the oil content, the faster the paint dries, and the more brittle it will be. Ignoring this practice, even in some alla prima painting, may result in a cracked and less durable paint film. (Full article...)

The depiction of night in paintings is common in Western art. Paintings that feature a night scene as the theme may be religious or history paintings, genre scenes, portraits, landscapes, or other subject types. Some artworks involve religious or fantasy topics using the quality of dim night light to create mysterious atmospheres. The source of illumination in a night scene—whether it is the moon or an artificial light source—may be depicted directly, or it may be implied by the character and coloration of the light that reflects from the subjects depicted. They are sometimes called nocturnes, or night-pieces, such as Rembrandt's The Night Watch, or the German Romantic Caspar David Friedrich's Two Men Contemplating the Moon of 1819.

In America, James Abbott McNeill Whistler titled works as nocturnes to identify those paintings with a "dreamy, pensive mood" by applying the musical term, and likewise also titled (and retitled) works using other music expressions, such as a "symphony", "harmony", "study" or "arrangement", to emphasize the tonal qualities and the composition and to de-emphasize the narrative content. The use of the term "nocturne" can be associated with the Tonalist movement of the American of the late 19th century and early 20th century which is "characterized by soft, diffused light, muted tones and hazy outlined objects, all of which imbue the works with a strong sense of mood." Along with winter scenes, nocturnes were a common Tonalist theme. Frederic Remington used the term as well for his nocturne scenes of the American Old West. (Full article...)

A glaze is a thin transparent or semi-transparent layer on a painting which modifies the appearance of the underlying paint layer. Glazes can change the chroma, value, hue and texture of a surface. Glazes consist of a great amount of binding medium in relation to a very small amount of pigment. Drying time will depend on the amount and type of paint medium used in the glaze. The medium, base, or vehicle is the mixture to which the dry pigment is added. Different media can increase or decrease the rate at which oil paints dry.

Often, because a paint is too opaque, painters will add a medium like linseed oil or alkyd to the paint to make them more transparent and pliable for the purposes of glazing. While these media are usually liquids, there are solid and semi-solid media used in the making of paints as well. For example, many classical oil painters have also been known to use ground glass and semi-solid resins to increase the translucency of their paint. (Full article...)

Illusionistic ceiling painting, which includes the techniques of perspective di sotto in sù and quadratura, is the tradition in Renaissance, Baroque and Rococo art in which trompe-l'œil, perspective tools such as foreshortening, and other spatial effects are used to create the illusion of three-dimensional space on an otherwise two-dimensional or mostly flat ceiling surface above the viewer. It is frequently used to create the illusion of an open sky, such as with the oculus in Andrea Mantegna's Camera degli Sposi, or the illusion of an architectural space such as the cupola, one of Andrea Pozzo's frescoes in Sant'Ignazio, Rome. Illusionistic ceiling painting belongs to the general class of illusionism in art, designed to create accurate representations of reality. (Full article...)

A fore-edge painting is an image painted on the unbound edges of a book visible when the pages of the book are fanned. It also can refer to an image that is visible on the closed edge of a book. References also refer to the paintings as disappearing or secret images, and they are often hidden beneath gilded edges.

Historically, fore-edge painting has had three purposes: identification, indication of ownership, or artistry. Possibly originating in the 10th century, the earliest known examples feature titles written on the closed edges of a book, symbolic imagery, or heraldic designs. The exact origins are debated among scholars. The technique of the hidden painting gained notable popularity in England during the 17th and 18th centuries. A fore-edge painting does not need to be painted on a book at the time of the book's creation. Unless a fore-edge artist was working with a bookseller or bookbinder, fore-edge paintings are applied sometime after the book has been published making the dating of the works difficult to ascertain unless the work is signed and dated.

Shigajiku (Japanese: 詩画軸, "poem-and-painting scrolls"), are a form of Japanese ink wash painting. These hanging scrolls depict poetic inscriptions at the top of the scroll and a painted image, usually a landscape scene, below. Buddhist monks of the gozan 五山 or Five Mountain monasteries of the early Muromachi Period (1336-1573) first introduced the poem-and-painting scrolls.

Shigajiku is a modern category given to the visual and literary culture of the Muromachi Period rooted in the Zen tradition. The most common visual aesthetic for shigajiku is a monochrome water and ink style of painting, suibokuga 水墨画, with only occasional traces of color throughout the scroll. (Full article...)

In two-dimensional works of art, such as painting, printmaking, photography or bas-relief, repoussoir (French: [ʁəpuswaʁ], pushing back) is an object along the right or left foreground that directs the viewer's eye into the composition by bracketing (framing) the edge. It became popular with Mannerist and Baroque artists, and is found frequently in Dutch seventeenth-century landscape paintings. Jacob van Ruisdael, for example, often included a tree along one side to enclose the scene (see illustration). Figures are also commonly employed as repoussoir devices by artists such as Paolo Veronese, Peter Paul Rubens and Impressionists such as Gustave Caillebotte. (Full article...)

Gongbi (simplified Chinese: 工笔; traditional Chinese: 工筆; pinyin: gōng bǐ; Wade–Giles: kung-pi) is a careful realist technique in Chinese painting, the opposite of the interpretive and freely expressive xieyi (寫意 'sketching thoughts') style.

The name is from the Chinese gong jin meaning 'tidy' (meticulous brush craftsmanship). The gongbi technique uses highly detailed brushstrokes that delimits details very precisely and without independent or expressive variation. It is often highly colored and usually depicts figural or narrative subjects. (Full article...)

A double-sided painting is a canvas which has a painting on either side. Historically, artists would often paint on both sides out of need of material. The subject matter of the two paintings was sometimes, although not normally, related.

Restoring and displaying double-sided paintings can pose additional challenges for museums and galleries. When repairing canvases, restorers must ensure that their restoration efforts do not damage the image on either side. They must also use stretcher bars that do not obscure either side of the image, and they cannot use crossbars to help keep tension. (Full article...)

Silk painting refers to paintings on silk. They are a traditional way of painting in Asia. Methods vary, but using traditional supplies of 100% silk fabric, stretched in a frame, and applying textile paints or dyes are the beginnings of the process of making textile art. (Full article...)

An atelier (French: [atəlje]) is the private workshop or studio of a professional artist in the fine or decorative arts or an architect, where a principal master and a number of assistants, students, and apprentices can work together producing fine art or visual art released under the master's name or supervision.

Ateliers were the standard vocational practice for European artists from the Middle Ages to the 19th century, and common elsewhere in the world. In medieval Europe this way of working and teaching was often enforced by local guild regulations, such as those of the painters' Guild of Saint Luke, and of other craft guilds. Apprentices usually began working on simple tasks when young, and after some years with increasing knowledge and expertise became journeymen, before possibly becoming masters themselves. This master-apprentice system was gradually replaced as the once powerful guilds declined, and the academy became a favored method of training. However, many professional artists continued using students and assistants as they had been in ateliers; sometimes the artist paid the student-assistants, while sometimes they paid the artist fees to learn.

Quadro riportato (plural quadri riportati) is the Italian phrase for "carried picture" or "transported paintings". It is used in art to describe gold-framed easel paintings or framed paintings that are seen in a normal perspective and painted into a fresco. The final effect is similar to illusionism, but the latter encompasses painted statues, reliefs and tapestries.

The ceiling is intended to look as if a framed painting has been placed overhead; there is no illusionistic foreshortening, figures appearing as if they were to be viewed at normal eye level. Mengs' Parnassus (1761) in the Villa Albani (now Villa Albani-Torlonia) is a famous example — a Neoclassical criticism against Baroque illusionism. Often, however, quadri riportati were combined with illusionistic elements, as in Annibale Carracci's Farnese Ceiling (1597–1600) in Rome. (Full article...)

The Gambier Parry process is a development of the classical technique of fresco for painting murals, named for Thomas Gambier Parry.

True fresco is the technique of painting on fresh lime plaster whereby the pigments are fixed by the carbonatation of the lime (calcium hydroxide). The technique requires no other binding medium and the fixing process produces a durable crystalline paint layer. However, only a limited range of pigments are suitable for true frescoes and the technique requires careful application under controlled conditions, and relatively low humidity thereafter. In some environments, conventional fresco colours can rapidly accumulate dirt and grime. The decoration of the new Houses of Parliament in the mid-nineteenth century saw an embarrassing failure of true fresco in England but had generated a revival in mural painting. (Full article...)

A rotary atomizer is an automatic electrostatic paint applicator used in high volume, automatic production painting environments. Also called a 'paint bell', "rotary bell atomizer" or 'bell applicator', it is preferred for high volume paint application for its superior transfer efficiency, spray pattern consistency, and low compressed air consumption, when compared to a paint spray gun. It can be mounted in a fixed position, reciprocating arm, or an industrial robot. (Full article...)

Graffiti (singular graffiti, or graffito only in graffiti archeology) is writing or drawings made on a wall or other surface, usually without permission and within public view. Graffiti ranges from simple written "monikers" to elaborate wall paintings, and has existed since ancient times, with examples dating back to ancient Egypt, ancient Greece, and the Roman Empire.

Modern graffiti is a controversial subject. In most countries, marking or painting property without permission is considered vandalism. Modern graffiti began in the New York City subway system and Philadelphia in the early 1970s and later spread to the rest of the United States and throughout the world. (Full article...)

Mineral painting or Keim's process, also known as stereochromy, is a mural or fresco painting technique that uses a water glass-based paint to maximize the lifetime of the finished work.

The name "stereochromy" was first used in about 1825 by Johann Nepomuk von Fuchs and Schlotthaurer. In the original technique, pigments were applied to plaster or stone and sealed with water glass to preserve and enhance the colors. The method was then improved in the 1880s by Adolf Wilhelm Keim and renamed mineral painting or Keim's process. (Full article...)

Leaf painting is the process of painting with dyed leaves. Deriving from Japan, China or India, it became popular in Vietnam. Its two main forms are: Cutting and pasting dry leaf to make leaf paintings or using paint to draw onto the surface of dry leaf to make leaf paintings.

Every product is unique, quite different from the others because of the leaves' veins, the forms, and the colors before or after dying. (Full article...)

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.

Drybrush is a painting technique in which a paint brush that is relatively dry, but still holds paint, is used to create a drawing or painting. Load is applied to a dry support such as paper or primed canvas. The resulting brush-strokes have a characteristic scratchy and textured look that lacks the smooth appearance that washes or blended paint commonly have. This technique can be used to achieve a blurred or soft appearance.

The technique of drybrush painting can be achieved with both water-based and oil-based media. With water-based media such as inks, acrylic paints, tempera-paints, or watercolor-paints, the brush is usually dry or squeezed dry of all water. The brush is loaded with paint that is highly viscous or thick and then applied to a dry support. With other water-based media, the brush is loaded with paint and then squeezed dry. When using oil-based media, such as oil-paint, similar techniques are used, although instead of water, the brush is used dry or any oil or solvent is removed. Because oil-paint has a longer drying-time than water-based media, brushing over or blending drybrush strokes is often avoided to preserve the distinctive look of the drybrush-painting-technique.
