Because the photographs are so durable, researchers have reworked Lippmann plates for use in archival data storage to replace hard drives. [13] Work began on the project after they were made aware data storage on the International Space Station requires daily maintenance because it can be damaged by cosmic rays and they recalled that silver halide would not be significantly affected by ...
The Fechner color effect is an illusion of color seen when looking at certain rapidly changing or moving black-and-white patterns. They are also called pattern induced flicker colors (PIFCs). A sample of a Benham's top (animated version) The effect is most commonly demonstrated with a device known as Benham's top (also called Benham's disk ...
A common example is the color variation that appears in pearlescent automobile finishes or "metallic" paper; e.g., Kodak Endura Metallic, Fujicolor Crystal Archive Digital Pearl. Observer metameric failure or observer metamerism can occur because of differences in color vision between observers.
The widely accepted interpretation of, e.g. the Poggendorff and Hering illusions as manifestation of expansion of acute angles at line intersections, is an example of successful implementation of a "bottom-up," physiological explanation of a geometrical–optical illusion. Ponzo illusion in a purely schematic form and, below, with perspective clues
A number of techniques exist to quantitatively analyze metallographic specimens. These techniques are valuable in the research and production of all metals and alloys and non-metallic or composite materials. Microstructural quantification is performed on a prepared, two-dimensional plane through the three-dimensional part or component.
Although op art is a unique style, it has similarities with styles such as abstract expressionism (color field painting). Although color field painting does not give us illusions, similarities can still be found. We can see that both of these styles are minimalist, only a few colors prevail, and no object or plot is shown.
Demonstration of the Bezold effect. The red seems lighter combined with the white, and darker combined with the black. The Bezold effect is an optical illusion, named after a German professor of meteorology Wilhelm von Bezold (1837–1907), who discovered that a color may appear different depending on its relation to adjacent colors.
In addition to the gestalt principles of perception, water-color illusions contribute to the formation of optical illusions. Water-color illusions consist of object-hole effects and coloration. Object-hole effects occur when boundaries are prominent where there is a figure and background with a hole that is 3D volumetric in appearance.
