Blackbody, английский
- Is defined as an object that absorbs all radiation that impinges on it at any wavelength.
- Абсолютно черное тело
- Hypothetical radiation source that yields the maximum radiation energy theoretically possible at a given temperature. a blackbody will absorb all incident radiation falling on it. by definition it has an emissivity of 1.0. see also emissivity.1 bolometer, infrared: thermal infrared detector in which electrical conductivity changes with temperature.
- In physics, a theoretical object whose incandescent radiation emission distribution (intensity versus wavelength) depends only on the absolute temperature of the blackbody and not on its internal nature or structure. a blackbody absorbs all energy falling on it. as the blackbody temperature increases, peak emission wavelength decreases. see also absorptivity; planck’s law; stefanboltzmann law; wien’s displacement law.

Black, английский
- Lacking hue and brightness; absorbing light without reflecting any of the rays composing it
- The absence of all reflected light; the color that is produced when an object absorbs all wavelengths from the light source.
- P. блэкуотер (ирландия)
- P. чёрная вольта (буркина-фасо и гана)
- Черный
- A body color that is true black over the entire body, but may have white leg and face markings.
- In the subtractive color model, black is not part of the visual spectrum and your eyes` and mind work together to create the color. when your eyes cannot pick up any light, your mind produces the color known as black. an easy way to think about this is that black is the absence of light. and white includes every color of light. in the additive color model, black is defined as the result of mixing together pigments, dyes, inks, or paint in the three primary colors. however, in actual practice, due to the impurity of pigments, when combining the three primaries, they often produce a color that is more brownish than black.

Black and white (b&w), английский
B&w film offers opportunities and challenges. foreground and background may merge in the absence of color separation. tips: use more back light or background light. view the scene with a b&w viewing glass. other differences: color temperature complications disappear and all those long-abandoned filters that turn blue skies black and trees white can be used again. last tip: while many of the black and white masters aren`t around, their masterpieces are. quote: the most difficult task for today`s director of photography is to "think" in black and white again. he must become mentally color-blind, imagining what each scene will look like on the screen when it loses the colors it has in reality. - nestor almendros [amwac]
Black and white effect, английский
One of a group of photo modifications someone can make to a color photo that mimic different effects that would be achieved by taking the same photo using black and white film stock. one effect uses strict conversion to monochrome by throwing away all of the color information. others mimic the result when a black and white photo is taken through a colored filter-€”orange, red, or yellow-€”to enhance or suppress certain color information. two effects perform strict conversions to monochrome and then apply a color tint-€”sepia or cyan-€”in one step.
