Temporary files such as DefaultTCCBSectionNNNN.lck and DefaultTCCBSectionNNNN.vm0 are created in a temporary folder of an OS In the case of prohibiting to create a development parameter file and a collateral information file at the " Function setting", a thumbnail will not be created. The file has the same base name as the case of the RAW file. spi is created in the same folder in which the RAW file exists in order to speed-up a thumbnail picture resulted from the executing a simple development of RAW data. are lost, when the software completes, or a new file/folder is loaded.Ī file with an extension. In addition, since a file cannot be created in write-protected folder and file, just as same as described above, development parameter information, reservation status, rotation information etc. are lost, when the software completes, or a new file/folder is loaded. In this case, development parameter information, reservation status, rotation information etc. Refer to ' Function Setting' for the setting. This file is called collateral information file. The files have the same base name as the case of the JPEG/TIFF files. spt are created in the same folder in which JPEG/TIFF files exist in order to save rotation information, user mark etc. This file is called development parameter file.įiles with extensions. spd is created in the same folder in which a RAW file exists in order to save development parameters, reservation status, rotation information, user mark etc. However, because there are only few softwares that can support the information, we recommend you to use 'Embedding ICC Profile' when you record colorspace information.ġ3.3.1 Development Parameter File and Collateral Information FileĪ file with an extension. In addition to sRGB colorspace information, adobeRGB color information can also be recorded from the Exif 2.21. This information is effective when the output file is processed with software that is in conformity with the Exif information. Since this software conforms to Exif 2.21, it outputs the color information that is in conformity with Exif. It is the standards that is widely adopted in cameras and utilities made in Japan.Īn outputted file can include the photos information such as shutter speed, aperture, shooting date, Exif thumbnail picture, colorspace information, and so forth by recording the Exif information can be recorded in the outputted file. Introduce the color deflection to adjust white balance on the subject that cannot be balanced with color temperature alone.Įxif information is the information of settings at shooting and characteristics of the picture. The length of the perpendicular line indicates black-body radiation deflection and is called color deflection in this software. It is considered that all colors on this perpendicular line are assumed as the same color temperature, and this line is called Isotemperature Line. To be more precise, by plotting light-source color on the coordinate system of CIE 1960 UCS, then from there dropping a perpendicular line to the black-body radiation locus, we take the portion as the color temperature. There are other light sources such as fluorescent tube, mercury-vapor tube and so forth, whose emission principle is completely different.įor these light sources, color temperature of the black-body radiator which is most visually alike is used. In a case of an electric light bulb, temperature of the filament is between 2000 - 3000degrees and the control temperature is between 2000 - 3000K. The sunlight temperature is around 5000 - 5500K. Since surface temperature of the sun is about 6000degrees, the sun emits light of 6000K color temperature.īefore the sunlight reaches the earth's surface, blue light scatters and is absorbed while it passes through atmosphere. The matter, which emits light, is called black-body radiator or Planck radiator. In this case, the colors of the light source can be represented as temperature.įor example, light emitted by the 1500degrees matter is described as color temperature 1500K (Kelvin), if the matter is 2000degrees, the color temperature is 2000K. Soon the light changes to orange, yellow, white, and then bluish white. When heating it gradually, first, it emits reddish light. The term color temperature is frequently used to represent colors of a light source. 13.1 Color Temperature and Color Deflection
