Sunburn effect (as measured by the UV index) is the product of the sunlight power spectrum (radiation intensity) and the erythemal action spectrum (skin sensitivity) across the range of UV wavelengths. [9] [10] The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface.
The Planckian locus on the MacAdam (u, v) chromaticity diagram. The normals are lines of equal correlated color temperature. The CIE 1960 color space ("CIE 1960 UCS", variously expanded Uniform Color Space, Uniform Color Scale, Uniform Chromaticity Scale, Uniform Chromaticity Space) is another name for the (u, v) chromaticity space devised by David MacAdam.
CIELUV is an Adams chromatic valence color space and is an update of the CIE 1964 (U*, V*, W*) color space (CIEUVW). The differences include a slightly modified lightness scale and a modified uniform chromaticity scale, in which one of the coordinates, v′, is 1.5 times as large as v in its 1960 predecessor.
The Fitzpatrick scale has been criticized for its Eurocentric bias and insufficient representation of global skin color diversity. [9] The scale originally was developed for classifying "white skin" in response to solar radiation, [2] and initially included only four categories focused on white skin, with "brown" and "black" skin types (V and VI) added as an afterthought.
The application of a texture in the UV space related to the effect in 3D. A representation of the UV mapping of a cube. The flattened cube net may then be textured to texture the cube. UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping.
The ultraviolet (UV) radiation in light is responsible for ink fading. As the intensity of UV radiation differs from place to place, the ink fading also depends on place. It will be more in areas with more UV radiation and vice versa. This difficulty is overcome by the bluewool testing method. Absolute values of fading will depend on light ...
A name for a cylindrical transformation of CIELuv (CIELCh uv) employed by Ihaka (2003) [1] and adopted by Zeileis et al. (2009, 2020). [2] [4] This name appears to be the one most commonly used in information visualization. Ihaka, Zeileis, and co-authors also provide software implementations and web pages to promote its use. [4]
Color temperature and Color Rendering Index (CRI) are the standards for measuring light. There is no technical definition of "full-spectrum" so it cannot be measured. To compare "full-spectrum" sources requires direct comparison of spectral distribution. Color emitted by a black body on a linear scale from 800 kelvins to 12200 kelvins
