Graphics software
In computer graphics, graphics software refers to a program or collection of programs that enable a person to or models visually on a computer. Computer graphics can be classified into two distinct categories: raster graphics and vector graphics, with further 2D and 3D variants. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that operate on both. It is simple to convert from vector graphics to raster graphics, but going the other way is harder.
Comparison of raster graphics editors
Raster graphics editors can be compared by many variables, including availability. Basic general information about the editor: creator, company, license, etc. The operating systems on which the editors can run natively, that is, without emulation, virtual machines or compatibility layers. In other words, the software must be specifically coded for the operation system; for example, Adobe Photoshop for Windows running on Linux with Wine does not fit.
Image tracing
In computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics. An image does not have any structure: it is just a collection of marks on paper, grains in film, or pixels in a bitmap. While such an image is useful, it has some limits. If the image is magnified enough, its artifacts appear. The halftone dots, film grains, and pixels become apparent. Images of sharp edges become fuzzy or jagged. See, for example, pixelation.
Graphic art software
Graphic art software is a subclass of application software used for graphic design, multimedia development, stylized , technical illustration, general , or simply to access graphic files. Art software uses either raster or vector graphic reading and editing methods to create, edit, and view art. Many artists and other creative professionals today use personal computers rather than traditional media.
Acutance
In photography, acutance describes a subjective perception of sharpness that is related to the edge contrast of an . Acutance is related to the amplitude of the derivative of brightness with respect to space. Due to the nature of the human visual system, an image with higher acutance appears sharper even though an increase in acutance does not increase real . Historically, acutance was enhanced chemically during development of a negative (high acutance developers), or by optical means in printing (unsharp masking).
Visual arts
The visual arts are art forms such as painting, drawing, printmaking, sculpture, ceramics, photography, video, filmmaking, design, crafts, and architecture. Many artistic disciplines, such as performing arts, conceptual art, and textile arts, also involve aspects of the visual arts as well as arts of other types. Also included within the visual arts are the applied arts, such as industrial design, graphic design, fashion design, interior design, and decorative art.
Digital photography
Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce s focused by a lens, as opposed to an exposure on photographic film. The digitized image is stored as a ready for further digital processing, viewing, electronic publishing, or digital printing. It is a form of digital imaging based on gathering visible light (or for scientific instruments, light in various ranges of the electromagnetic spectrum).
Raster graphics editor
A raster graphics editor is a computer program that allows users to create and images interactively on the computer screen and save them in one of many raster graphics (also known as bitmap images) such as JPEG, PNG, and GIF. Vector graphics editors are often contrasted with raster graphics editors, yet their capabilities complement each other. The technical difference between vector and raster editors stem from the difference between vector and raster images. Vector graphics are created mathematically, using geometric formulas.
Unsharp masking
Unsharp masking (USM) is an technique, first implemented in darkroom photography, but now commonly used in software. Its name derives from the fact that the technique uses a blurred, or "unsharp", negative image to create a mask of the original image. The unsharp mask is then combined with the original positive image, creating an image that is less blurry than the original. The resulting image, although clearer, may be a less accurate representation of the image's subject.
Photograph manipulation
Photograph manipulation involves the of a photograph. Some photograph manipulations are considered to be skillful artwork, while others are considered to be unethical practices, especially when used to deceive. Photographs may be manipulated for political propaganda, to improve the appearance of a subject, for entertainment, or as humor. Depending on the application and intent, some photograph manipulations are considered an art form because they involve creation of unique images and in some instances, signature expressions of art by photographic artists.
