While several vendors offer HDR screens, and Intel has built HDR support into the latest generations of its products, the only operating system that currently supports HDR is Windows ® 10 using DirectX*. 2020 Standard for 4K ultra-high Definition (UHD) content creation and consumption, wide color gamut, and HDR with 10-bit enablement.
In addition, 7th generation and later Intel ® Xeon ® processors and Intel ® Core™ processors support the Rec.
Krita paintings software#
The Krita team has also built up a relationship with Intel, using Intel’s multithreading technology and software development tools to enhance software application performance 1. Krita development is based on the popular Qt* software development kit (Qt SDK). Krita* has been in continuous development since 2003 by volunteers and sponsored full-time developers. An Overview of the Krita* HDR Implementation HDR workflows generating images for HDR displays support a minimum of 10-bit color depth from start to finish, including the initial capture or creation of the images. Instead, they use a function called Perceptual Quantizer (PQ), which extends the dynamic range to both sun-bright and very dark values. When displaying colors, HDR displays do not use traditional exponential gamma correction.
Whereas conventional screens are limited to a few hundred of brilliance, HDR screens can achieve 1,000 nits or more. For example, they can show the lifelike effect of a sunbeam piercing through a window instead of a subdued, paper-style imitation. With HDR, screens can realistically depict sources of light. This color space offers a significantly richer gamut of colors, notably with many more variations of greens and reds. This extra capacity for storing information allows HDR displays to go beyond the basic sRGB color space used previously and display the colors of Recommendation ITU-R BT.2020 (Rec. Encoding was limited to a depth of 8 bits some laptop screens only handled 6 bits per pixel.īy comparison, HDR standards typically define 10 bits per pixel, with some rising to 16. Possibilities of storing color, contrast, or other information about each pixel were limited. A Revolution in the Display of Color and Brightnessīefore the arrival of HDR, displays were calibrated to comply with the D65 standard of whiteness, corresponding to average midday light in Western and Northern Europe. This white paper gives a high-level description of the development process to equip Krita with HDR. Krita and Intel engineers have also worked together to enhance Krita performance through Intel ® multithreading technology, while Intel’s built-in support of HDR provides further acceleration. The pioneering approach of the Krita team can be leveraged by developers to add HDR to other applications. With HDR, Krita now opens the door for professionals and amateurs to a vastly extended range of colors and luminance. With more than two million downloads per year, the program enables users to create and manipulate illustrations, concept art, comics, matte paintings, game art, and more. Krita*, a leading open source application for artists, has become one of the first digital painting software to achieve true high dynamic range (HDR) capability.
