i_seldom_do: in progress. some in-progress teaser pics of my 'Hajimari' solo show coming up at Jonathan Levine Gallery in NY this coming Saturday. will post full images of all pieces after opening night happens. ;) 20 Tutorials for Learning Digital Painting Techniques I’ve always loved browsing the insanely detailed and realistic artwork created by digitally painting in Photoshop, so this year I’m planning on setting aside some time to learn the basics myself. I’ve read through numerous online tutorials and have hand picked the best to share with you today. All the tutorials showcased in this post describe the step by step process and offer useful tips to help you get started with the art of digital painting. Despite being an extremely popular subject it’s pretty difficult finding guides or tutorials that actually explain the process in detail.

Iron(III) oxide - Sciencemadness Wiki Iron(III) oxide, often referred to as red iron oxide, is the chemical compound with chemical formula Fe2O3. It is the main component of rust and acts as the oxidizing agent in the classic thermite reaction with aluminium. Properties Chemical Iron oxide is a typical metal oxide. It will react with acids to form the iron salt, so iron(III) oxide is a useful starting point to make chemicals such iron acetate. A mixture of red iron oxide and aluminium powders is the classic thermite mixture. Red iron oxide is sometimes added to KNO3 and sugar mixtures to help accelerate the reaction, which is needed when making 'rocket candy' rockets. Physical Availability Sometimes used as a colouring agent for things such as concrete. Due to the well known thermite reaction, it is commonly available in large amounts online. Preparation Iron can be slowly oxidized by oxygen in the presence of salt water to red iron oxide. A more effective way to produce large amounts of iron oxide is through electrolysis. Projects

Judith Ann Braun's Fingers Are Magical With an art career spanning more than three decades, Judith Ann Braun has tested the limits of her artistic musculature. She began as a self-described “realistic figure painter,” and worked through the struggles common to anyone who endeavors upon an artistic pursuit, that of searching for one’s own voice in the chosen medium. Fast forward to the 21st century where the evolution of Braun’s work has brought us to the Fingerings series, a collection of charcoal dust landscapes and abstracts “painted” using not brushes but her fingertips.

Mixing Up Illustration: Combining Analog And Digital Techniques Advertisement In the digital age, don’t forget to use your digits! Your hands are the original digital devices— Lynda Barry People often ask how I arrived at a finished illustration. Honestly, it’s different every time, but it always starts with a hand-drawn sketch. Sketching It Out Concepting for me always starts with pencil and paper. Researching This is the most underestimated part of the process, but one of the most important. Some artists who always inspire me are Mary Blair, Alice Provensen, Charley Harper, Maurice Noble and Eyvind Earle. Also, if I’m drawing an elephant’s skin, or wood on a camera, or a band on a helmet, I’ll want to take a close look at the real thing. Crafting Your Own Brushes I do this because I want my brushes to be my own. Some rough crosshatching for the elephant’s skin, with an oil pastel on drawing paper. Scanning It All In Scan everything: the initial sketch, the textures, anything you’ve made to this point. Here is a scan of my original sketch. (al)

Pigment Synthetic ultramarine pigment is chemically identical to natural ultramarine Pigment Colours - Classification A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. In 2006, around 7.4 million tons of inorganic, organic and special pigments were marketed worldwide. Physical basis[edit] A wide variety of wavelengths (colors) encounter a pigment. The appearance of pigments is intimately connected to the color of the source light. Color spaces used to represent colors numerically must specify their light source. Sunlight encounters Rosco R80 "Primary Blue" pigment. Other properties of a color, such as its saturation or lightness, may be determined by the other substances that accompany pigments. History[edit] Before the Industrial Revolution, the range of color available for art and decorative uses was technologically limited. Mineral pigments were also traded over long distances, often at great cost. Swatches[edit]

DIY Artwork - Easy Paint Projects - Painting Ideas UPDATE: The long weekend is the perfect time to start some new projects, so why not try this awesome (and so easy) artwork DIY? This story was originally published on July 25. If there are two things that have been commanding our attention lately, they're cool artwork and chevron prints. So, we were obviously pretty stoked to find a way to incorporate both — for cheap! Inspired by the work of artist Nancy Ramirez, two stellar Refinery29 interns collaborated on this easy-does-it way to spice up an empty wall. From the moment we spied this Nancy Ramirez painting on Pinterest, we were smitten. To do this project, you'll need: A canvas, in any size you choose Painter's tape Acrylic paints in your preferred colors, plus one bottle of white paint A paintbrush (or two, if you'd rather alternate brushes than wash one between colors) Scissors A disposable plate, wax paper, or scrap cardboard to use as a palette Paper towels or a drop cloth to cover your work area Et voilà!

Survival Guide for Art Students I met with the editors of Dover Publishing a while ago. They publish a lot of classic books on art instruction from days of yore. I told them that most of what I know about drawing and painting comes from studying their books. They asked me for a list of the ten art instruction books that I thought were most useful, with a blurb about why I love each one. Bridgman's Life Drawing by George Bridgman Bridgman's legendary figure drawing demonstrations at the Art Students League of New York have inspired generations of artists, from Norman Rockwell to Frank Frazetta. John Vanderpoel, who studied in France at the Académie Julian, offers a classical approach to figure drawing, noteworthy for its timeless grace. Harold Speed's classic text bridges the often-difficult gap between drawing and painting. Speed's book on painting builds on his drawing book, offering painting instruction as it was practiced in the Royal Academy. Here's the list again in no particular order.

Preparing a DVD-R to act as a diffraction grating Main image - A segment of a DVD-R bottom layer with the photo-reactive dye removed See also - Does leaving the dye on a DVD-R grating make any difference? All DVD-Rs are made with two layers of moulded polycarbonate about 0.58mm thick, glued together. The process starts with splitting the two polycarbonate layers apart. A sharp craft knife can be applied to the edge and wiggled (very carefully) until it gains purchase between the two layers and starts them peeling apart. The problem I found with the initial split is that I tended to end up with a lot of aluminium and purple tinted dye on the bottom half of the disc. NOTE - Further experiments show that the dye is easily soluble in plain water. The dye dissolves easily, but any aluminium silvering left on the bottom disc is quite hard to shift. If you get stuck with a lot of aluminium left on the bottom half, then getting rid of it is harder than dissolving the dye.

Early Human Evolution: Early Human Culture Paralleling the biological evolution of early humans was the development of cultural technologies that allowed them to become increasingly successful at acquiring food and surviving predators. The evidence for this evolution in culture can be seen especially in three innovations: Tool Making Some chimpanzee communities are known to use stone and wood as hammers to crack nuts and as crude ineffective weapons in hunting small animals, including monkeys. However, they rarely shape their tools in a systematic way to increase efficiency. The most sophisticated chimpanzee tools are small, slender tree branches from which they strip off the leaves. These twigs are then used as probes for some of their favorite foods--termites and ants. Throughout most of the Homo erectus geographic range, there is clear evidence of progressive improvement in tool making over time.

Do-It-Yourself DNA | STEM Activity Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? All living organisms have DNA. DNA, which is short for deoxyribonucleic acid, is the blueprint for almost everything that happens inside the cells of an organism — overall, it tells the organism how to develop and function. This activity is not appropriate for use as a science fair project.
