Illumination is a concept in visual arts. By manipulating the lighting, an Artist can create a specific atmosphere for their work of art. Additionally, it can help the artist add depth to their work. [1]
The illumination of the subject of a drawing or painting is a key element in creating an artistic piece, and the interplay of light and shadow is a valuable method in the artist's toolbox. The placement of the light sources can make a considerable difference in the type of message that is being presented. Multiple light sources can wash out any wrinkles in a person's face, for instance, and give a more youthful appearance. In contrast, a single light source, such as harsh daylight, can serve to highlight any texture or interesting features.
Caravaggio's early biographers, Giovanni Pietro Bellori and Joachim von Standrart both stated that Caravaggio worked in a dark room and illuminated his subjects with a single light source from above. [2] Caravaggio's pioneering use of light and shade is known as chiaroscuro. [3]
Processing of illumination is an important concept in computer vision and computer graphics.
Michelangelo Merisi da Caravaggio, known mononymously as Caravaggio, was an Italian painter active in Rome for most of his artistic life. During the final four years of his life, he moved between Naples, Malta, and Sicily until his death. His paintings have been characterized by art critics as combining a realistic observation of the human state, both physical and emotional, with a dramatic use of lighting, which had a formative influence on Baroque painting.
In art, chiaroscuro is the use of strong contrasts between light and dark, usually bold contrasts affecting a whole composition. It is also a technical term used by artists and art historians for the use of contrasts of light to achieve a sense of volume in modelling three-dimensional objects and figures. Similar effects in cinema, and black and white and low-key photography, are also called chiaroscuro. Taken to its extreme, the use of shadow and contrast to focus strongly on the subject of a painting is called tenebrism.
A shadow is a dark area on a surface where light from a light source is blocked by an object. In contrast, shade occupies the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.
Shading refers to the depiction of depth perception in 3D models or illustrations by varying the level of darkness. Shading tries to approximate local behavior of light on the object's surface and is not to be confused with techniques of adding shadows, such as shadow mapping or shadow volumes, which fall under global behavior of light.
Low-key lighting is a style of lighting for photography, film or television. It is a necessary element in creating a chiaroscuro effect. Traditional photographic lighting uses a key light, a fill light and a back light for illumination. Low-key lighting often uses only a key light, optionally controlled with a fill light or a simple reflector.
Umber is a natural earth pigment consisting of iron oxide and manganese oxide; it has a brownish color that can vary among shades of yellow, red, and green. Umber is considered one of the oldest pigments known to humans, first seen in Ajanta Caves in 200 BC – 600 AD. Umber's advantages are its highly versatile color, warm tone, and quick drying abilities. While some sources indicate that umber's name comes from its geographic origin in Umbria, other scholars suggest that it derives from the Latin word umbra, which means "shadow". The belief that its name derives from the word for shadow is fitting, as the color helps create shadows. The color is primarily produced in Cyprus. Umber is typically mined from open pits or underground mines and ground into a fine powder that is washed to remove impurities. In the 20th century, the rise of synthetic dyes decreased the demand for natural pigments such as umber.
Tenebrism, from Italian tenebroso, also occasionally called dramatic illumination, is a style of painting using especially pronounced chiaroscuro, where there are violent contrasts of light and dark, and where darkness becomes a dominating feature of the image. The technique was developed to add drama to an image through a spotlight effect, and is common in Baroque paintings. Tenebrism is used only to obtain a dramatic impact while chiaroscuro is a broader term, also covering the use of less extreme contrasts of light to enhance the illusion of three-dimensionality.
The term composition means "putting together". It can be thought of as the organization of the elements of art according to the principles of art. Composition can apply to any work of art, from music through writing and into photography, that is arranged using conscious thought.
Apollodorus Skiagraphos was an influential Ancient Greek painter of the 5th century BC whose work has since been entirely lost. Apollodorus left a technique behind known as skiagraphia, a way to easily produce shadow, that affected the works not only of his contemporaries but also of later generations. This shading technique uses hatched areas to give the illusion of both shadow and volume.
The Adoration of the Shepherds is an oil on canvas painting by the Italian artist Michelangelo Merisi, commonly known as Caravaggio. The Adoration of the Shepherds measures 83.07 x 123.62 in. It was commissioned for the Capuchin Franciscans and was painted in Messina for the Church of Santa Maria degli Angeli in 1609 just one year before the artist's death. It is now in the Interdisciplinary Regional Museum of Messina.
The Incredulity of Saint Thomas is a painting of the subject of the same name. It is one of the most famous paintings by the Italian Baroque master Caravaggio, c. 1601–1602. There are two autograph versions of Caravaggio's The Incredulity of Saint Thomas, an ecclesiastical "Trieste" version for Girolamo Mattei which is now in a private collection and a secular "Potsdam" version for Vincenzo Giustiniani that later entered the Royal Collection of Prussia, survived the Second World War unscathed, and can now be admired in the Palais at Sanssouci, Potsdam.
Adam de Coster was a Flemish painter. He was a prominent member of the Antwerp Caravaggisti. These Caravaggisti were part of an international movement of European artists who interpreted the work of Caravaggio and the followers of Caravaggio in a personal manner. He is mainly known for his genre scenes with strong chiaroscuro effects. He was called a Pictor Noctium because of his preference for tenebrist scenes.
Matthias Stom or Matthias Stomer was a Dutch, or possibly Flemish, painter who is only known for the works he produced during his residence in Italy. He was influenced by the work of non-Italian followers of Caravaggio in Italy, in particular his Dutch followers often referred to as the Utrecht Caravaggists, as well as by Jusepe de Ribera and Peter Paul Rubens. He did not share the other Northern Caravaggisti's preference for humorous, and sometimes scabrous, genre scenes and elaborate decorative allegories but favored stories from the bible instead. He worked in various locations in Italy where he enjoyed the patronage of religious institutions as well as prominent members of the nobility.
Cangiante is a painting technique where, when using relatively pure colors, one changes to a different, darker color to show shading, instead of dulling the original color by darkening it with black or a darker related hue. According to the theory of the art historian Marcia B. Hall, which has gained considerable acceptance, this is one of the canonical painting modes of the Renaissance; i.e. one of the four modes of painting colours available to Italian High Renaissance painters, along with sfumato, chiaroscuro and unione. The word itself is the present participle of the Italian verb cangiare. This approach to the use of color is sometimes referred to as "cangiantismo".
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.
The Resurrection by Cecco del Caravaggio, the Italian Baroque painter, is the only painting known for certain to be his. It was commissioned in 1619 by Piero Guicciardini, the Tuscan ambassador to Rome. Through the use of alternate strong lights and deep shadows the chiaroscuro highlights the vividness of the dramatic scene. One of Cecco's most notable works, the painting is in the permanent collection of the Art Institute of Chicago.
Penitent Magdalene is a 1616–1618 painting by the Italian baroque artist Artemisia Gentileschi. This painting hangs in the Pitti Palace in Florence. The subject is the biblical figure Mary Magdalene, but the painting references another biblical woman, Mary, the sister of Lazarus. This painting was likely painted during Gentileschi's Florentine period.
Low-key photography is a genre of photography consisting of shooting dark-colored scenes by lowering or dimming the "key" or front light illuminating the scene, and emphasizing natural or artificial light only on specific areas in the frame. This photographic style is usually used to create a mysterious atmosphere, that only suggests various shapes, often graphic, letting the viewer experience the photograph through subjective interpretation and often implies painting objects or the human body with black non-toxic dyes or pigments.
Light in painting fulfills several objectives like, both plastic and aesthetic: on the one hand, it is a fundamental factor in the technical representation of the work, since its presence determines the vision of the projected image, as it affects certain values such as color, texture and volume; on the other hand, light has a great aesthetic value, since its combination with shadow and with certain lighting and color effects can determine the composition of the work and the image that the artist wants to project. Also, light can have a symbolic component, especially in religion, where this element has often been associated with divinity.
