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. 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.
Oil painting is the process of painting with pigments with a medium of drying oil as the binder. It has been the most common technique for artistic painting on wood panel or canvas for several centuries, spreading from Europe to the rest of the world. The advantages of oil for painting images include "greater flexibility, richer and denser colour, the use of layers, and a wider range from light to dark". But the process is slower, especially when one layer of paint needs to be allowed to dry before another is applied.
A pastel is an art medium in the form of a stick, consisting of powdered pigment and a binder. The pigments used in pastels are similar to those used to produce some other colored visual arts media, such as oil paints; the binder is of a neutral hue and low saturation. The color effect of pastels is closer to the natural dry pigments than that of any other process. Pastels have been used by artists since the Renaissance, and gained considerable popularity in the 18th century, when a number of notable artists made pastel their primary medium.
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.
Stone carving is an activity where pieces of rough natural stone are shaped by the controlled removal of stone. Owing to the permanence of the material, stone work has survived which was created during our prehistory or past time.
Digital illustration or computer illustration is the use of digital tools to produce images under the direct manipulation of the artist, usually through a pointing device such as a tablet or a mouse. It is distinguished from computer-generated art, which is produced by a computer using mathematical models created by the artist. It is also distinct from digital manipulation of photographs, in that it is an original construction "from scratch". Photographic elements such as background or texture may be incorporated into such works, but they are not necessarily the primary basis.
Scratchboard or scraperboard, is a form of direct engraving where the artist scratches off dark ink to reveal a white or colored layer beneath. Scratchboard refers to both a fine-art medium, and an illustrative technique using sharp knives and tools for engraving into a thin layer of white China clay that is coated with dark, often black India ink. There is also foil paper covered with black ink that, when scratched, exposes the shiny surface beneath. Scratchboard can be used to yield highly detailed, precise and evenly textured artwork. Works can be left black and white, or colored.
A writing implement or writing instrument is an object used to produce writing. Writing consists of different figures, lines, and or forms. Most of these items can be also used for other functions such as painting, drawing and technical drawing, but writing instruments generally have the ordinary requirement to create a smooth, controllable line.
A medical illustration is a form of biological illustration that helps to record and disseminate medical, anatomical, and related knowledge.
Max Brödel was a medical illustrator. Born in Leipzig, Germany, he began his artistic career after graduating from the Leipzig Academy of Fine Arts, working for Dr. Carl Ludwig. Under Ludwig's instruction, Brödel gained a basic knowledge of medicine and became recognized for his detailed medical illustrations. In the late 1890s, he was brought to the Johns Hopkins School of Medicine in Baltimore to illustrate for Harvey Cushing, William Halsted, Howard Kelly, and other notable clinicians. In addition to being a prolific medical illustrator, he developed new artistic techniques such as the carbon dust technique that helped the advancement of the quality and accuracy of medical illustrations for physicians. In 1911, he presided over the creation of the first Department of Art as Applied to Medicine; located at the Johns Hopkins School of Medicine, it continues to train medical illustrators to this day. His graduates spread out across the world, and have founded a number of other academic programs.
Parchment craft, also known as Pergamano, is the art of embellishing and decorating parchment paper through the use of techniques such as embossing, perforating, stippling, cutting and coloring.
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. The pattern is created on the printing plate either in engraving by gouging out the dots with a burin, or through an etching process. Stippling was used as an adjunct to conventional line engraving and etching for over two centuries, before being developed as a distinct technique in the mid-18th century.
Audrey Juliet Arnott (1901–1974) was a medical illustrator who worked with the neurosurgeon Hugh Cairns at the London Hospital and followed him to Oxford when he was appointed Nuffield Professor of Surgery in 1939. She founded the Medical Artists Association of Great Britain from her home in Wolvercote in 1949.
Biological illustration is the use of technical illustration to visually communicate the structure and specific details of biological subjects of study. This can be used to demonstrate anatomy, explain biological functions or interactions, direct surgical procedures, distinguish species, and other applications. The scope of biological illustration can range from the whole organism level to microscopic.
A paintbrush is a brush used to apply paint or ink. A paintbrush is usually made by clamping bristles to a handle with a ferrule. They are available in various sizes, shapes, and materials. Thicker ones are used for filling in, and thinner ones are used for details. They may be subdivided into decorators' brushes used for painting and decorating and artists' brushes use for visual art.
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. Used with a soft lithographic crayon or carbon pencil, coquille produces a shading effect similar to hand stippling in a fraction of the time. The material is especially useful for works to be reproduced in print, such as scientific illustration and cartooning. However, coquille is also delicate and cannot withstand vigorous pressure from an eraser.
Maria Torrence Wishart was a Canadian medical illustrator and the founder of the University of Toronto's Art as Applied to Medicine program. She was educated at Johns Hopkins School of Medicine under Max Brödel, and in 1925 returned to Canada to found the Department of Medical Art Service in the Faculty of Medicine.
Grattage is a technique in surrealist painting which consists of "scratching" fresh paint with a sharp blade.
Dorothy Davison was a British author and medical illustrator, whose work was well known for its artistic merit. She founded the Medical Artists' Association in 1949, and trained many young medical artists in Manchester.
Elizabeth Huntington Brödel, also seen as Elizabeth H. Broedel, was an American medical illustrator and daughter of medical illustrator Max Brödel.
