illuminant

For a given illuminant, its white point is uniquely defined.

The employment of petroleum oil as an illuminant was at its beginning.

A given white point, on the other hand, generally does not uniquely correspond to only one illuminant.

It can also be used in textile manufacture, soap making and as an illuminant.

An illuminant is characterized by its relative spectral power distribution.

White Balance - color correction to conform to the viewing illuminant.

They are derived from Illuminant A by using a liquid filters.

Cappen and Jamie each had that, but no illuminant like honest men.

The sample color in the test illuminant is:

Illuminant and white point are separate concepts.

Whale oil was used as a cheap illuminant, though it gave off a strong odor when burnt and was not very popular.

It is useful as a theoretical reference; an illuminant that gives equal weight to all wavelengths, presenting an even color.

The set of three tristimulus coordinates of an illuminant is called a white point.

A color temperature meter measures the color temperature of an incident illuminant.

A standard illuminant is a theoretical source of visible light with a profile (its spectral power distribution) which is published.

Around 1848, Samuel Kier realized the potential of the medicinal oil as an illuminant.

The spectrum of a standard illuminant, like any other profile of light, can be converted into tristimulus values.

The subscripts indicate the cone response for white under the test (w) and reference illuminant (wr).

For more than thirty years the arc light remained an expensive laboratory experiment; but the coming of the dynamo placed that illuminant on a commercial basis.

Moonbeam & Illuminant for Fancy feat.

Blanco mentioned that the seeds yield limpid, odorous oil which is employed in food as an illuminant.

The seed is very high in flammable oils, like a candlenut, so it is able to be burnt as an illuminant.

The maximum absolute error for color temperatures ranging from 2856 (illuminant A) to 6504 (D65) is under 2 K.

The best color matrix for adapting to a change in illuminant is not necessarily a diagonal matrix in a fixed color space.

New competition also emerged in the 1880s in the form of water gas, an improved illuminant patented by Thaddeus Lowe.
