Carbon Dust
Carbon dust is an artistic technique in which carbon dust is applied to a surface via dry brushes. Highlights may be painted on or scratched out later in the process. Dust is prepared by rubbing carbon pencils against an abrasive surface, such as a metal file. The technique was popularized by Max Brödel (1870-1941) and became widely used among medical and scientific illustrators in the twentieth century. Brödel described his technique in detail while drafting a proposed book on medical illustration, that was later published as an appendix in his biography. Very early in his career he employed several traditional drawing and wash techniques to render illustrations. Dissatisfied with traditional techniques he explored other means of rendering that would allow him to realistically render the brilliant highlights and fine fibers of living tissue. In 1894 after arriving in Baltimore and after some experimentation he began using the dust of Wolff carbon pencils applied to Ross .00 s ...

Carbon Dust Skull
Carbon () is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—its atom making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. Three isotopes occur naturally, C and C being stable, while C is a radionuclide, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity. Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Carbon's abundance, its unique diversity of organic compounds, and its unusual ability to form polymers at the temperatures commonly encountered on Earth, enables this element to serve as a common element of all known life. It is the second most abundant element in the human body by mass (about 18.5%) after oxygen. The atoms of ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pencil
A pencil () is a writing or drawing implement with a solid pigment core in a protective casing that reduces the risk of core breakage, and keeps it from marking the user's hand. Pencils create marks by physical abrasion, leaving a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which dispense liquid or gel ink onto the marked surface. Most pencil cores are made of graphite powder mixed with a clay binder. Graphite pencils (traditionally known as "lead pencils") produce grey or black marks that are easily erased, but otherwise resistant to moisture, most chemicals, ultraviolet radiation and natural aging. Other types of pencil cores, such as those of charcoal, are mainly used for drawing and sketching. Coloured pencils are sometimes used by teachers or editors to correct submitted texts, but are typically regarded as art supplies, especially those with cores made from wax-based binders that tend to smear when ...

Max Brödel
Max Brödel (June 8, 1870 – October 26, 1941) 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 wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Illustration
A medical illustration is a form of biological illustration that helps to record and disseminate medical, anatomical, and related knowledge. History Medical illustrations have been made possibly since the beginning of medicine in any case for hundreds (or thousands) of years. Many illuminated manuscripts and Arabic scholarly treatises of the medieval period contained illustrations representing various anatomical systems (circulatory, nervous, urogenital), pathologies, or treatment methodologies. Many of these illustrations can look odd to modern eyes, since they reflect early reliance on classical scholarship (especially Galen) rather than direct observation, and the representation of internal structures can be fanciful. An early high-water mark was the 1543 CE publication of Andreas Vesalius's ''De Humani Corporis Fabrica Libri Septum'', which contained more than 600 exquisite woodcut illustrations based on careful observation of human dissection. Since the time of the Leonardo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
:Category:Scientific Illustrators
Scientific illustrators represent visually aspects of science, particularly observations of the natural world. The emphasis in scientific illustration is on accuracy and utility, rather than on aesthetics, although scientific illustrators are skilled artists and often known for aesthetic values. Scientific illustration was an important part of scientific communication prior to photography. Since the development of photography, scientific illustration is particularly useful for selective renderings rather than lifelike accuracy. For instance, illustrations of stellar phenomena that are not visible to the human eye; or medical illustrations, which highlight particular parts of a system. See also technical illustration, which aims to illustrate scientific principles, engineering schemata, inventions and technologies. Illustrators * Artists by genre {{CatAutoTOC ...

Coquille Board
Coquille board, also known as stipple board, is a type of 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, ... 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. References Paper Illustration {{Art-material-stub ...

Artistic Techniques
Art is a diverse range of human activity, and resulting product, that involves creative or imaginative talent expressive of technical proficiency, beauty, emotional power, or conceptual ideas. There is no generally agreed definition of what constitutes art, and its interpretation has varied greatly throughout history and across cultures. In the Western tradition, the three classical branches of visual art are painting, sculpture, and architecture. Theatre, dance, and other performing arts, as well as literature, music, film and other media such as interactive media, are included in a broader definition of the arts. Until the 17th century, ''art'' referred to any skill or mastery and was not differentiated from crafts or sciences. In modern usage after the 17th century, where aesthetic considerations are paramount, the fine arts are separated and distinguished from acquired skills in general, such as the decorative or applied arts. The nature of art and related concepts, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
