The most common form of calibration aims at adjusting cameras, scanners, monitors, and printers for photographic reproduction. The aim is that a printed copy of a photograph appears identical in saturation and dynamic range to the original or a source file on a computer display. This means that three independent calibrations need to be performed:
Color management is necessary because different devices have different color capabilities and characteristics. For example, a monitor may display colors differently than a printer can reproduce them. Without color management, the same image may appear differently on different devices, leading to inconsistencies and inaccuracies.
Color calibration of a monitor using ColorHug2, an open-source colorimeter, placed on the screen. A tristimulus colorimeter, colloquially shortened to colorimeter or colourimeter, is used in digital imaging to profile and calibrate output devices.
Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.
A good monitor with proper calibration shows the six numbers on the right in both bars, a cheap monitor shows only four numbers. Given a desired display-system gamma, if the observer sees the same brightness in the checkered part and in the homogeneous part of every colored area, then the gamma correction is approximately correct.
Color profile viewer on KDE Plasma 5, showing an ICC color profile. Linux color management has the same goal as the color management systems (CMS) for other operating systems, which is to achieve the best possible color reproduction throughout an imaging workflow from its source (camera, video, scanner, etc.), through imaging software (Digikam, darktable, RawTherapee, GIMP, Krita, Scribus, etc ...
Angelina Jolie laughed when a reporter asked her what a biopic of her life might look like and said in part, "Let’s hope there isn’t one about my life"
