  2. Light in painting - Wikipedia

    en.wikipedia.org/wiki/Light_in_painting

    Port with the disembarkation of Cleopatra in Tarsus (1642), by Claude Lorrain, Musée du Louvre, Paris. Light in painting fulfills several objectives like, both plastic and aesthetic: on the one hand, it is a fundamental factor in the technical representation of the work, since its presence determines the vision of the projected image, as it affects certain values such as color, texture and ...

    en.wikipedia.org/wiki/Incandescent_light_bulb

    In 1761, Ebenezer Kinnersley demonstrated heating a wire to incandescence. [8] However such wires tended to melt or oxidize very rapidly (burn) in the presence of air. [9] Limelight became a popular form of stage lighting in the early 19th century, by heating a piece of calcium oxide to incandescence with an oxyhydrogen torch. [10]

    Venus de Milo, at the Louvre. Art history is, briefly, the history of art—or the study of a specific type of objects created in the past. [1]Traditionally, the discipline of art history emphasized painting, drawing, sculpture, architecture, ceramics and decorative arts; yet today, art history examines broader aspects of visual culture, including the various visual and conceptual outcomes ...

  5. Candoluminescence - Wikipedia

    en.wikipedia.org/wiki/Candoluminescence

    Candoluminescence is the light given off by certain materials at elevated temperatures (usually when exposed to a flame) that has an intensity at some wavelengths which can, through chemical action in flames, be higher than the blackbody emission expected from incandescence at the same temperature. [1]

  6. Hockney–Falco thesis - Wikipedia

    en.wikipedia.org/wiki/Hockney–Falco_thesis

    The hypothesis that technology was used in the production of Renaissance Art was not much in dispute in early studies and literature. [4]In his treatise on perspective, early Baroque painter Cigoli (1559 – 1613) expressed his belief that a more likely explanation of the origin of painting lies in people conserving the image of the camera obscura by applying colours and tracing the contours ...

  7. Thermal radiation - Wikipedia

    en.wikipedia.org/wiki/Thermal_radiation

    The radiation is not monochromatic, i.e., it does not consist of only a single frequency, but comprises a continuous spectrum of photon energies, its characteristic spectrum. If the radiating body and its surface are in thermodynamic equilibrium and the surface has perfect absorptivity at all wavelengths, it is characterized as a black body. A ...

  9. Luminescence - Wikipedia

    en.wikipedia.org/wiki/Luminescence

    As the definition does not fully describe the phenomenon, quantum mechanics is employed where it is defined as there is no change in spin multiplicity from the state of excitation to emission of light. [2] Phosphorescence, traditionally defined as persistent emission of light after the end of excitation. As the definition does not fully ...
