By looking at a horizontally repeating pattern, but converging the two eyes at a point behind the pattern, it is possible to trick the brain into matching one element of the pattern, as seen by the left eye, with another (similar looking) element, beside the first, as seen by the right eye.
Because of the long history of the use of black ink on white paper, "white space" is the term often used in graphics to identify the same separation. Elements of an image that distract from the intended subject, or in the case of photography, objects in the same focal plane, are not considered negative space. Negative space may be used to ...
However, the brain undergoes deeper processing to resolve the ambiguity. For example, consider an image that involves an opposite change in magnitude of luminance between the object and the background (e.g. From the top, the background shifts from black to white, and the object shifts from white to black).
Overlapping of aerial photos means that around 60% of the covered area of every aerial image overlays that of the one before it. [2] Every object along the flying path can be observed twice at a minimum. [2] The purpose of overlapping the aerial photography is to generate the 3D topography or relief when using a stereoscope for interpretation. [2]
Bottom photo taken with the same camera, but with additional wide angle lens. The effect of aberration is visible around the dark edges (especially on the right). LCA is defined as the "variation of the eye's focusing power for different wavelengths". [14] This chromatic difference varies from about 400 nm to 700 nm across the visible spectrum ...
Specific black-and-white photographs. It should not contain the images (files) themselves, nor should it contain free- or fair-use images which do not have associated articles. See also Category:Color photographs
In computing terminology, black-and-white is sometimes used to refer to a binary image consisting solely of pure black pixels and pure white ones; what would normally be called a black-and-white image, that is, an image containing shades of gray, is referred to in this context as grayscale. [2]
The Cornsweet illusion creates a boundary between two identically-shaded regions with a discontinuous gradient, resulting in the opposing sides appearing to be different. The Chubb illusion evokes this effect by surrounding zones with others of different, distinct shades, with the relative brightness or darkness of the surrounded area appearing ...
