The number of pixels or picture elements contained in one linear inch in a digitally stored image. PS, PSE: Photoshop, Photoshop Elements. Commercial computer applications developed by Adobe for editing digital images. [20] RGB: RGB color space. An additive colour space that uses the primary colours of red, green and blue to create any colour.
The process or technique of combining visual elements from separate sources into a single image, particularly so as to create the illusion that all of those elements are parts of the same scene. In modern cinema, compositing is usually achieved through digital image manipulation in post-production. continuity
Photographic composition techniques are used to set up the elements of a picture. These are the techniques which resembles the way we humans normally see a view Some of the main techniques that are: Simplicity (photography) Symmetrical balance; Asymmetrical balance; Radial balance; Rule of thirds; Leading lines [1] Golden ratio; Framing ...
The preferred orientation of an aerial photograph is closely related to the position of the Sun and the shadow element. [2] In the Northern Hemisphere, the south direction is always the position of the sun. [2] Therefore, shadows are usually formed on the north side. [2] This then affects the shadow element in aerial photographs.
Visual rhetoric studies how humans use images to communicate. Elements of images, such as size color, line, and shape, are used to convey messages. [19] In images, meanings are created by the layout and spatial positions of these elements. [19] The entities that constitute an image are socially, politically, and culturally constructed.
Visual metaphors are a type of metaphor.There are two types: spatial metaphors and stylistic metaphors. [6] Spatial visual metaphors include where objects are located, their size, whether they are abstract or realistic, and how it is arranged in respect to other objects.
A digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis, respectively. [1]
An illuminated object will scatter light toward a lens and the lens will collect and focus the light to create the image. The ratio of the height of the image to the height of the object is the magnification. The spatial extent of the image surface and the focal length of the lens determines the field of view of the lens.
