A pixel artist or pixologist is a graphic designer who specializes in computer art and can refer to a number of artistic and professional disciplines which focus on visual communication and presentation.[1][2][3] Similar to chromoluminarism used in the pointillism style of painting, in which small distinct points of primary colors create the impression of a wide selection of secondary and intermediate colors, a pixel artist works with pixels, the smallest piece of information in an image.[4] The technique relies on the perceptive ability of the eye and mind of the viewer to mix the color spots into a fuller range of tones. Pixel art is often utilitarian and anonymous.[3][5] Pixel design can refer to both the process (designing) by which the communication is created and the products (designs) which are generated.[6]

Common uses of pixel design include print and broadcast media, web design and games.[7][3][1] For example, a product package might include a logo or other artwork, organized text and pure design elements such as shapes and color which unify the piece. Composition is one of the most important features of design especially when utilizing pre-existing materials or using diverse elements. Pixologists can also be a specialist in computer animation such as Computer Animation Production System users in post production of animated films and rendering (computer graphics) images like raster graphics.

In the 2000s, pixel artists such as Tyler West, Stephane Martiniere and Daniel Dociu have gained international notoriety and artistic recognition, due in part to the popularity of computer and video games.[8][9] For instance the E3 Media and Business Summit, an annual trade show for the computer and video games industry, has a concurrent juried art show, "Into the Pixel" starting in 2003.[9][10][11][12] Jurist and Getty Research Institute curator Louis Marchesano noted that most of the works were concept pieces used in the development of games.[10]

History

Computer art started in 1960s and by its nature is evolutionary since changes in technology and software directly effect what is possible. The term pixel art was first published by Adele Goldberg and Robert Flegal of Xerox Palo Alto Research Center in 1982.[13] Adobe Systems, founded in 1982, developed the Postscript language and digital fonts, making drawing painting and image manipulation software popular.[14] Adobe Illustrator, a vector drawing program based on the Bezier curve, was introduced in 1987 and Adobe Photoshop followed in 1990.[14] Adobe Flash, a popular set of multimedia software used to add animation and interactivity to web pages, was introduced in 1996.

Background

Imagine the smiley face in the top left corner as an RGB bitmap image. When zoomed in, it might look like the big smiley face to the right. Every square represents a pixel. Zooming in further, the individual pixels can be analyzed, with their colors adjusted by adding the values for red, green and blue.

A pixologist is one of the new media artists that employs technology while also utilizing traditional media and art forms.[2][15][3] They may have a fine arts background such as photography, painting or drawing but self-taught designers and artists are also able to accomplish this work.[2][3] Pixology skills often require the art of imaging and conceptual artists may need to employ a full range of artistic and technological skills.[15][16]

In digital imaging, a pixel (picture element) is the smallest piece of information in an image.[4] The word pixel is based on a contraction of pix (for "pictures") and el (for "element"); similar formations with el for "element" include voxel, luxel, and texel.[17][18] Pixels are normally arranged in a regular 2-dimensional grid, and are often represented using dots, squares, or rectangles. Each pixel is a sample of an original image, where more samples typically provide a more accurate representation of the original. The intensity of each pixel is variable; in color systems, each pixel has typically three or four components such as red, green, and blue, or cyan, magenta, yellow, and black.

Neuroplasticity is a key element of observing a many pixel images. While two individuals will observe the same photons reflecting off a photorealistic image and hitting their retinas, someone whose mind has been primed with the theory of pointillism may see a very different image as the image is interpreted in the visual cortex.[19]

Techniques

A pixel does not need to be rendered as a small square. This image shows alternative ways of reconstructing an image from a set of pixel values, using dots, lines, or smooth filtering.

The total number of pixels (image resolution), and the amount of information in each pixel (often called color depth) determine the quality of an image. For example, an image that stores 24 bits of color-information per pixel (the standard for computer displays since around 1995) can represent smoother degrees of shading than one that only stores 16 bits per pixel, but not as smooth as one that stores 48 bits. Likewise, an image sampled at 640 x 480 pixels (and therefore containing 307,200 pixels) will look rough and blocky compared to one sampled at 1280 x 1024 (1,310,720 pixels). Because it takes a large amount of data to store a high-quality image, computer software often uses data compression techniques to reduce this size for images stored on disk. Some techniques sacrifice information, and therefore image quality, in order to achieve a smaller file-size. Computer scientists refer to compression techniques that lose information as lossy compression.

Modern computer-monitors typically display about 72 to 130 pixels per inch (PPI), and some modern consumer printers can resolve 2400 dots per inch (DPI) or more; determining the most appropriate image resolution for a given printer-resolution can pose difficulties, since printed output may have a greater level of detail than a viewer can discern on a monitor. Typically, a resolution of 150 to 300 pixel per inch works well for 4-color process (CMYK) printing.

Drawings usually start with what is called the line art, which is the basic line that defines the item the artist intends to create. Linearts are usually traced over scanned drawings and are often shared among other pixel artists. Other techniques, some resembling painting, also exist. The limited palette often implemented into pixel art usually promotes the use of dithering in order to achieve different shades and colors; anti-aliasing is also used. A pixel artist will exponentially increase the size of whatever they are working on to make adjustments as needed and then view the results until desired changes are achieved.[6]
