	Color temperature - Wikipedia, the free encyclopedia
		The lamp's color temperature is the temperature in kelvins at which the heated fl-body radiator matches the hue of the lamp.
		Color temperatures and mireds are convertible to each other via a simple formula (see the mired page for details of the computations, and the reasons for the use of the alternative unit).
		The CIE developed a newer model for describing and rating light sources, called the color rendering index, which is a mathematical formula describing how well a light source's illumination of eight sample patches compares to the illumination provided by a reference source.

	Color rendering capacity - Wikipedia, the free encyclopedia
		Color rendering properties of light can be examined from, at least, two perspectives.
		First, when one focuses on the accuracy of color rendering, one can make use of the CIE color rendering index, which tells how closely the color appearances of 8 test samples lit by a light of given spectral composition resemble those of the same samples lit by a Planck radiator with the same color temperature.
		Second, when one focuses on the effectiveness of color rendering, one can turn to the Color Rendering Capacity(CRC), which indicates the upper limit for the number of those colors which can be vividly rendered by a light of given spectral composition.

	Capacity - Psychology Central
		Cranial capacity is a measure of the volume of the interior of the skull
		Color rendering capacity, in photometry, is a measure of how broad a color space can be perceived under the illumination of a specific light.
		Capacity utilization is a term in economics referring to the relationship of actual to potential output of industries.

		Studio lighting and color-rendering (the capacity of a light to reproduce the color effects of daylight) can be complicated issues, but by taking the time to learn a bit about the types of lighting available, you can improve your painting studio.
		I assume that by “color correcting light systems” you mean “full-spectrum” lamps, which simulate the effects, in color temperature and color-rendering ability, of natural daylight by covering the spectrum of light more fully than either incandescents or fluorescents alone.
		In either case, the color temperature is higher than that of regular lamps, which gives you better color-rendering, and there are no hot or cool spots with these lamps because the illumination is combined in one fixture and diffused through a filter.

	Effect of Veiling Reflections on Vision of Colored Objects
		Color rendering, meaning the effects of the source SPD, is not a variable in this discussion.
		The effect of adding white to a particular color is shown by an arrow, with its tail at the initial saturation (c) and lightness (L) and arrowhead at the new values.
		If a shiny colored object is lighted by a compac source near a dark area, the source image will be a bright white highlight, and the image of the dark area will define a region in which the object's pigmentation can be clearly seen.

	Color management and color science: Introduction
		These color primaries (shown on the left) have a curious property-- they have negative energy in portions of their spectra, i.e., they are not physically realizable.
		The colors in the diagram are not accurate, but the representation is about as good as can be obtained with the limited color gamut of a computer monitor.
		The colors may be the objects sensed by a scanner or produced by a printer or monitor.

		Color management is provided through a closed-loop system within which any new device or imaging medium to be used is first calibrated in a process that takes about 20 minutes.
		A block of 256 CMYK colors is first scanned and the results are analyzed by the program, after which a new palette of 4,096 colors is printed.
		With wider paper or multiple colors, the use of color is limited to those areas of the page that pass under a given head.

		You may need to attach a profile to an image or change its color space, for example, when you are working in a color space other than sRGB and need to prepare the image for the Web.

		This pattern of results suggests that many of the visibility advantages attributed to the use of fluorescent colors in safety applications may be mediated by top-down attentional mechanisms rather than bottom-up (preattentive) mechanisms as previously assumed.
		One of the assumptions that pervades the literature on the visibility of fluorescent colored materials used in safety research is that fluorescent colors "grab your attention".
		During the initial 32 trials, the position of the four non-fluorescent colored stimuli (red, green, yellow, orange) as well as the position of the four arrow directions were completely randomized.

		The result is that the 'mixture' of colors is 'unscrambled': each of the individual colors becomes visible in the form of a spectrum of colors.
		The nerve endings inside the eye are not equally responsive to all colors: in well-lit conditions they work most efficiently within the green-yellow areas of the spectrum and least efficiently at the extreme ends of the spectrum (i.e.

	Rendering
		Rendering speed /is/ effected by the scale of your geometry, though you probably won't see much difference unless your scenes already take a few hours to render.
		When you render, this plane will not be visible in the RGB channel, and the only portion of it that'll be visible in the Alpha channel will be whatever falls under a shadow cast by another object.
		If I render the image at 640 x 480 with reflections, it renders within 20 minutes (btw- my system is a PC with 128MB of memory with a Pentium 200mhz processor), but when I choose SHADOWS in the render options, it literally takes days to render.

		This pattern of results suggests that many of the visibility advantages attributed to the use of fluorescent colors in safety applications may result due to top-down attentional mechanisms rather than bottom-up (preattentive) mechanisms as previously assumed.

		During the initial 32 trials, the position of the four non-fluorescent colored stimuli (red, green, yellow, orange) as well as the orientation of the four arrow directions were completely randomized.
		Second, the fluorescent yellow sign generated a performance curve that was virtually identical to the other two fluorescent colors despite the fact that the “subjective appearance” of the fluorescent yellow sign is relatively unremarkable.
		Hence, profound differences in the subjective appearance of different fluorescent colors failed to be associated with differences in search conspicuity as assessed in the current set of experiments.

	Why Digitize
		One must think about the nature of the source materials (color, fl and white, or shades of gray) and the use of the images (who will be consulting them and for what) when making decisions about the parameters for image capture.
		While work is ongoing to address the quality control and variability of computer monitors, as yet the lack of control over display mechanisms constitutes one of the weakest links in the digital chain of transmission.
		Image processing—the manipulation of images after initial digital capture—can greatly expand the capacity of the researcher to compare and contrast details that the human eye cannot see unaided.

	Color Balance
		Generally, networkable color ink-jets aren’t as fast as lasers, and their print engines aren’t as robust.
		The base price tends to be higher than it is for ink-jets, but the cost of their consumables tends to be lower, leading to lower per-page print costs and lower total cost of ownership over time.
		Color control software such as Xerox’s TekColor should be bundled with your printer to assure automatic adjustment of photos, graphics and text for the best color reproduction.

		Abstract: This paper describes a new hardware volume rendering algorithm for time-varying data.
		The algorithm uses the Time-Space Partitioning (TSP) tree data structure to identify regions within the data that have spatial or temporal coherence.
		By using this coherence, the rendering algorithm can improve performance when the volume data are larger than the texture memory capacity by decreasing the amount of textures required.
