// cameraCCTSetting -- color temperature, in Kelvin, configured

// The cameraCCTSetting is primarily forensic, and indicates the

// cameraTintSetting -- green / magenta tint configured for the physical

//
// The cameraTintSetting is primarily forensic. There is no vendor-

// diagram. One camera vendor might choose a color space (e.g. the
// CIE 1960 UCS) and have a unit amount of tint represent some delta uv
// distance from the point by the cammeraCCTSetting and a tint value of 0.
// Another might choose to express the effect of tint by analogy to a
// traditional unit from a film workflow, e.g. a Kodak or Rosco color
// correction filter. About the only guaranteed commonality is that all
// camera vendor tint schemes have positive values shift the adopted
// scene white towards green, and negative values toward magenta.
//
// If the camera vendor maps cameraCCTSetting to a point defined by
// a linear crossfade between a Planckian blackbody locus and loci of
// CIE D Series illuminants, the slope of the tint isotherm at the
// exact points where the linear crossfade starts and ends can be
// indeterminate and an inverse mapping from chromaticity to a pair
// of CCT and tint can be one-to-many.
//

//
// Note that this is not necessarily (or even probably) the same
// chromaticity as that of the scene adopted white stored in an
// adoptedNeutral attribute (if present).
//
// For example, if a physical digital cinema camera was configured with
// a CCT of 3200K and a tint of -3 (in some camera vendor dependent unit),
// and the camera output had been processed such that the image containing
// this attribute was encoded as per SMPTE ST 2065-4:2023, then

// in order to tell applications that read the file whether the pixel data
// must be cleaned up prior to image processing operations such as flattening.

// the actual state of the pixels.  Application software may assume that the
// attribute is valid, as long as the software will not crash or lock up if
// any pixels are inconsistent with the deepImageState attribute.
