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.

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...)

A wash is a term for a visual arts technique resulting in a semi-transparent layer of colour. A wash of diluted ink or watercolor paint applied in combination with drawing is called pen and wash, wash drawing, or ink and wash. Normally only one or two colours of wash are used; if more colours are used the result is likely to be classified as a full watercolor painting.

The classic East Asian tradition of ink wash painting uses black ink in various levels of dilution. Historically associated with the four arts of the scholar-officials, the technique was often applied to landscapes in traditional Chinese, Japanese, and Korean painting. (Full article...)

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^{[weasel words]}—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...)

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 entitled 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.

In the art world, if an artwork exists in several versions, the one known or believed to be the earliest is called the prime version. Many artworks produced in media such as painting or carved sculpture which create unique objects are in fact repeated by their artists, often several times. It is regarded as a matter of some importance both by art historians and the art market to establish which version has "priority", that is to say was the original work. The presumption usually is that the prime version is the finest, and perhaps the most carefully done, though some later versions can be argued to improve on the originals.

In many periods the later "repetitions" were often produced by the workshop of the master, with varying degrees of supervision and direct attention from him. This was especially the case with official portraits of monarchs and politicians, which in the Early Modern period were often ordered in large numbers of versions from the court artist as diplomatic gifts. "Prime version" is normally only used when there is another version by the same artist, or his workshop. Other versions by other artists are called copies. Sometimes "reduced versions" that are considerably smaller than the prime one are made. Especially in the case of 19th-century repetitions, the term autograph replica is used of repetitions by the original artist. (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...)

The conservation and restoration of paintings is carried out by professional painting conservators. Paintings cover a wide range of various mediums, materials, and their supports (i.e. the painted surface made from fabric, paper, wood panel, fabricated board, or other). Painting types include fine art to decorative and functional objects spanning from acrylics, frescoes, and oil paint on various surfaces, egg tempera on panels and canvas, lacquer painting, water color and more. Knowing the materials of any given painting and its support allows for the proper restoration and conservation practices. All components of a painting will react to its environment differently, and impact the artwork as a whole. These material components along with collections care (also known as preventive conservation) will determine the longevity of a painting. The first steps to conservation and restoration is preventive conservation followed by active restoration with the artist's intent in mind. (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...)

A self-portrait is a portrait an artist makes of themself. Although self-portraits have been made since the earliest times, the practice of self-portraiture only gaining momentum in the Early Renaissance in the mid-15th century that artists can be frequently identified depicting themselves as either the main subject, or as important characters in their work. With better and cheaper mirrors, and the advent of the panel portrait, many painters, sculptors and printmakers tried some form of self-portraiture. Portrait of a Man in a Turban by Jan van Eyck of 1433 may well be the earliest known panel self-portrait. He painted a separate portrait of his wife, and he belonged to the social group that had begun to commission portraits, already more common among wealthy Netherlanders than south of the Alps. The genre is venerable, but not until the Renaissance, with increased wealth and interest in the individual as a subject, did it become truly popular.

By the Baroque period, most artists with an established reputation at least left drawings of themselves. Printed portraits of artists had a market, and many were self-portraits. They were also sometimes given as gifts to family and friends. If nothing else, they avoided the need to arrange for a model, and for the many professional portrait-painters, a self-portrait kept in the studio acted as a demonstration of the artist's skill for potential new clients. The unprecedented number of self-portraits by Rembrandt, both as paintings and prints, made clear the potential of the form, and must have further encouraged the trend. (Full article...)

A picture frame is a protective and decorative edging for a picture, such as a painting or photograph. It makes displaying the work safer and easier and both sets the picture apart from its surroundings and aesthetically integrates it with them. (Full article...)

Panoramic paintings are massive artworks that reveal a wide, all-encompassing view of a particular subject, often a landscape, military battle, or historical event. They became especially popular in the 19th century in Europe and the United States, inciting opposition from some writers of Romantic poetry. A few have survived into the 21st century and are on public display. Typically shown in rotundas for viewing, panoramas were meant to be so lifelike they confused the spectator between what was real and what was image.

In China, panoramic paintings are an important subset of handscroll paintings, with some famous examples being Along the River During the Qingming Festival and Ten Thousand Miles of the Yangtze River. (Full article...)

The depiction of night in paintings is common in art in Asia. Paintings that feature the night scene as the theme are mostly portraits and landscapes. Some artworks which involve religious or fantasy topics use the quality of dim night light to create mysterious atmospheres. They tend to illustrate the illuminating effect of the light reflection on the subjects under either moonlight or artificial light sources. (Full article...)

The Peintres de la Réalité [pɛ͂tʀ də la ʀealite] (French for "Painters of Reality") were founded after the Second World War by Henri Cadiou to connect artists who were specialized on still life and genre motifs. It later evolved to the Mouvement trompe l'oeil / Réalité. The painting of the group is no reappearance of antiquity or of the 17th century, but the logical consequence of the place in the 20th century development of a realism that has taken over the sequence of surrealism to the modern trompe-l'œil to lead.

1973, the group exhibited at the Cultural Center of New York and the Corcoran Gallery in Washington. In 1989, after the death of Henri Cadiou, Pierre Gilou continued his father's work within the group. In 1993, the group had a sensational success as part of the Grand Palais in Paris, the exhibition "le triomphe du trompe-l'oeil" had more than 65,000 visitors in two weeks. (Full article...)

The conservation-restoration of panel paintings involves preventive and treatment measures taken by paintings conservators to slow deterioration, preserve, and repair damage. Panel paintings consist of a wood support, a ground (linen or parchment sized with glues, resin, and gesso), and an image layer (encaustic, tempera, oil). They are typically constructed of two or more panels joined together by crossbeam braces which can separate due to age and material instability caused by fluctuations in relative humidity and temperature. These factors compromise structural integrity and can lead to warping and paint flaking. Because wood is particularly susceptible to pest damage, an IPM plan and regulation of the conditions in storage and display are essential. Past treatments that have fallen out of favor because they can cause permanent damage include transfer of the painting onto a new support, planing, and heavy cradling. Today's conservators often have to remediate damage from previous restoration efforts. Modern conservation-restoration techniques favor minimal intervention that accommodates wood's natural tendency to react to environmental changes. Treatments may include applying flexible battens to minimize deformation or simply leaving distortions alone, instead focusing on preventive care to preserve the artwork in its original state.

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...)

An "overdoor" (or "Supraporte" as in German, or "sopraporte" as in Italian) is a painting, bas-relief or decorative panel, generally in a horizontal format, that is set, typically within ornamental mouldings, over a door, or was originally intended for this purpose. (Full article...)

A hierarchy of genres is any formalization which ranks different genres in an art form in terms of their prestige and cultural value.

In literature, the epic was considered the highest form, for the reason expressed by Samuel Johnson in his Life of John Milton: "By the general consent of criticks, the first praise of genius is due to the writer of an epick poem, as it requires an assemblage of all the powers which are singly sufficient for other compositions." Below that came lyric poetry, and comic poetry, with a similar ranking for drama. The novel took a long time to establish a firm place in the hierarchy, doing so only as belief in any systematic hierarchy of forms expired in the 19th century. (Full article...)

Oil painting reproductions are paintings that have been created by copying in oils an original oil painting by an artist.

Oil painting reproductions are distinct from original oil painting such as are often of interest to collectors and museums. Oil painting reproduction can, however, sometimes be regarded as artworks in themselves. (Full article...)

The history of Western painting represents a continuous, though disrupted, tradition from antiquity until the present time. Until the mid-19th century it was primarily concerned with representational and traditional modes of production, after which time more modern, abstract and conceptual forms gained favor.

Initially serving imperial, private, civic, and religious patronage, Western painting later found audiences in the aristocracy and the middle class. From the Middle Ages through the Renaissance painters worked for the church and a wealthy aristocracy. Beginning with the Baroque era artists received private commissions from a more educated and prosperous middle class. The idea of "art for art's sake" began to find expression in the work of the Romantic painters like Francisco de Goya, John Constable, and J. M. W. Turner. During the 19th century commercial galleries became established and continued to provide patronage in the 20th century. (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 figure painting is a work of fine art in any of the painting media with the primary subject being the human figure, whether clothed or nude. Figure painting may also refer to the activity of creating such a work. The human figure has been one of the constant subjects of art since the first Stone Age cave paintings, and has been reinterpreted in various styles throughout history.

Unlike figure drawings which are usually nudes, figure paintings are often clothed depictions which may be either historically accurate or symbolic.
Figure painting is not synonymous with figurative art, which may depict real objects of any kind (including humans and animals). (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.

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.

Spray painting is a painting technique in which a device sprays coating material (paint, ink, varnish, etc.) through the air onto a surface. The most common types employ compressed gas—usually air—to atomize and direct the paint particles.

Spray guns evolved from airbrushes, and the two are usually distinguished by their size and the size of the spray pattern they produce. Airbrushes are hand-held and used instead of a brush for detailed work such as photo retouching, painting nails, or fine art. Air gun spraying uses generally larger equipment. It is typically used for covering large surfaces with an even coating of liquid. Spray guns can either be automated or hand-held and have interchangeable heads to allow for different spray patterns.

Distemper is a decorative paint and a historical medium for painting pictures, and contrasted with tempera. The binder may be glues of vegetable or animal origin (excluding egg). Soft distemper is not abrasion resistant and may include binders such as chalk, ground pigments, and animal glue. Hard distemper is stronger and wear-resistant and can include casein or linseed oil as binders. (Full article...)

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...)

Brain painting is a non-invasive P300-based brain-computer interface (BCI) that allows painting without the use of muscular activity. The technology combines electroencephalography, signal processing algorithms and visual stimulation on a monitor to detect where the user focuses his attention, allowing him to voluntarily trigger commands to a painting software. The research project aims at assisting people afflicted with the Locked-in syndrome due to neurological or neuromuscular disease (e.g. amyotrophic lateral sclerosis ALS), who are severely restricted in communication with their environment, and therefore cut off from the possibility of creative expression.

Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.

An addition to the electrostatic coating (or e-coating) process is dipping electrically conductive parts into a tank of paint that is then electrostatically charged. The ionic bond of the paint to the metal creates the paint coating, in which its thickness is directly proportional to the length of time the parts are left in the tank and the time the charge remains active. Once the parts are removed from the paint tank, they are rinsed off to remove any residual paint that is not ionically bonded, leaving a thin film of electrostatically bonded paint on the surface of the part.

Intonaco is an Italian term for the final, very thin layer of plaster on which a fresco is painted. The plaster is painted while still wet, in order to allow the pigment to penetrate into the intonaco itself. An earlier layer, called arriccio, is laid slightly coarsely to provide a key for the intonaco, and must be allowed to dry, usually for some days, before the final very thin layer is applied and painted on. In Italian the term intonaco is also used much more generally for normal plaster or mortar wall-coatings in buildings.

Intonaco is traditionally a mixture of sand (with granular dimensions less than two millimeters) and a binding substance. (Full article...)

Freehand brush work is a genre of Chinese traditional painting which includes poem, calligraphy, painting and seal. In Chinese called Hsieh yi (traditional Chinese: 寫意; simplified Chinese: 写意; pinyin: Xiěyì), which literally means "writing ideas". It was formed in a long period of artistic activities and promoted by the literati. Through the inheritance and development in the past dynasties, freehand brush work has gradually become the most influential and popular genre.

The freehand brush work emphasizes the semblance in the spiritual aspect. This kind of artwork does not chase for the physical similarity and the cooperation of reality. And it might be the essence of freehand brush work that it mostly grasps the most obvious or essential spiritual characteristics. The first rule of freehand brush work is the use of connotation which is a kind of spiritual meaning. It focuses on the personality and the cooperation of every element in the painting.

Bark painting is an Australian Aboriginal art form, involving painting on the interior of a strip of tree bark. While examples of painted bark shelters were found in the south-eastern states (then colonies) of Tasmania, Victoria, and New South Wales in the 19th century, as well as later on bark shelters in northern Australia, it is now typically only found as a continuing form of artistic expression in Arnhem Land and other regions in the Top End of Australia, including parts of the Kimberley region of Western Australia.

Bark paintings were traditionally produced (especially among the Yolngu peoples) for instructional and ceremonial purposes and were transient objects. Today, they are keenly sought after by collectors and public arts institutions. (Full article...)

Cobweb painting, sometimes known as gossamer painting, is the delicate process of painting on canvases made from caterpillar and spider webs that have been collected, layered, cleaned, and framed. Fewer than 100 cobweb paintings are known to exist, many of which are housed in private collections. (Full article...)

Illusionism in art history means either the artistic tradition in which artists create a work of art that appears to share the physical space with the viewer or more broadly the attempt to represent physical appearances precisely – also called mimesis. The term realist may be used in this sense, but that also has rather different meanings in art, as it is also used to cover the choice of ordinary everyday subject-matter, and avoiding idealizing subjects. Illusionism encompasses a long history, from the deceptions of Zeuxis and Parrhasius to the works of muralist Richard Haas in the twentieth century, that includes trompe-l'œil, anamorphosis, optical art, abstract illusionism, and illusionistic ceiling painting techniques such as di sotto in sù and quadratura. Sculptural illusionism includes works, often painted, that appear real from a distance. Other forms, such as the illusionistic tradition in the theatre, and Samuel van Hoogstraten's "peepshow"-boxes from the seventeenth century, combine illusionistic techniques and media.

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...)

According to the theory of the art historian Marcia B. Hall, which has gained considerable acceptance, unione (Italian: [uˈnjoːne]) is one of the canonical painting modes of the Renaissance; that is, one of four modes of painting colours available to Italian High Renaissance painters, along with sfumato, chiaroscuro and cangiante. Unione was developed by Raphael, who exemplified it in the Stanza della Segnatura.

Unione is similar to sfumato, but is more useful for the edges of chiaroscuro, where vibrant colors are involved. As with chiaroscuro, unione conveys the contrasts, and as sfumato it strives for harmony and unity, but also for coloristic richness. Unione is softer than chiaroscuro in the search for the right tonal key. There should be the harmony between light and dark, without the excesses and accentuation of a chiaroscuro mode.

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...)

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. (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...)

Craquelure (French: craquelure; Italian: crettatura) is a fine pattern of dense cracking formed on the surface of materials. It can be a result of drying, shock, aging, intentional patterning, or a combination of all four. The term is most often used to refer to tempera or oil paintings, but it can also develop in old ivory carvings or painted miniatures on an ivory backing. Recently, analysis of craquelure has been proposed as a way to authenticate art.

In ceramics, craquelure in ceramic glazes, where it is often a desired effect, is called "crackle"; it is a characteristic of Chinese Ge ware in particular. This is usually differentiated from crazing, which is a glaze defect in firing, or the result of aging or damage. (Full article...)

Trompe-l'œil (French for 'deceive the eye'; /trɒmpˈlɔɪ/ tromp-LOY; French: [tʁɔ̃p lœj] ^ⓘ) is an artistic term for the highly realistic optical illusion of three-dimensional space and objects on a two-dimensional surface. Trompe-l'œil, which is most often associated with painting, tricks the viewer into perceiving painted objects or spaces as real. Forced perspective is a related illusion in architecture.

Pin striping (or pinstriping) is the application of a very thin line of paint or other material called a pin stripe, and is generally used for decoration. Freehand pin stripers use a specialty brush known as a pinstriping brush.

Automotive, bike shops, and do-it-yourself car and motorcycle mechanics use paint pin striping to create their own custom look on the automotive bodies and parts. (Full article...)

Paint by number or painting by numbers kits are self-contained painting sets, designed to facilitate painting a pre-designed image. They generally include brushes, tubs of paint with numbered labels, and a canvas printed with borders and numbers. The user selects the color corresponding to one of the numbers then uses it to fill in a delineated section of the canvas, in a manner similar to a coloring book.

The kits were invented, developed and marketed in 1950 by Max S. Klein, an engineer and owner of the Palmer Paint Company in Detroit, Michigan, United States, and Dan Robbins, a commercial artist. When Palmer Paint introduced crayons to consumers, they also posted images online for a "Crayon by Number" version. (Full article...)

Polychrome is the "practice of decorating architectural elements, sculpture, etc., in a variety of colors." The term is used to refer to certain styles of architecture, pottery, or sculpture in multiple colors.

When looking at artworks and architecture from antiquity and the European Middle Ages, people tend to believe that they were monochrome. In reality, the pre-Renaissance past was full of colour, and all the Greco-Roman sculptures and Gothic cathedrals, that are now white, beige, or grey, were initially painted in bright colours. As André Malraux stated: "Athens was never white but her statues, bereft of color, have conditioned the artistic sensibilities of Europe [...] the whole past has reached us colorless." Polychrome was and is a practice not limited only to the Western world. Non-Western artworks, like Chinese temples, Oceanian Uli figures, or Maya ceramic vases, were also decorated with colours.

Verdaccio is an Italian name for the mixture of black, white, and yellow pigments resulting in a grayish or yellowish (depending on the proportion) soft greenish brown.

Verdaccio became an integral part of fresco painting, in which this color is used for defining tonal values, forming a complete monochromatic underpainting. Often architectural details in frescoes are left in verdaccio without any additional color layers; a notable example is the ceiling of the Sistine Chapel, where verdaccio underpainting can be clearly seen, left as it is on all architectural details of the composition.

Pointillism (/ˈpwæ̃tɪlɪzəm/, also US: /ˈpwɑːn-ˌ ˈpɔɪn-/) is a technique of painting in which small, distinct dots of color are applied in patterns to form an image.

Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism. The term "Pointillism" was coined by art critics in the late 1880s to ridicule the works of these artists, but is now used without its earlier pejorative connotation. The movement Seurat began with this technique is known as Neo-impressionism. The Divisionists used a similar technique of patterns to form images, though with larger cube-like brushstrokes.

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...)
