![]() For optical applications, this bounded range can be expressed in terms of 2-based logarithmic intervals, the exposure values (EV), also called stops in the photographic industry, that are believed to be evenly spaced in human vision. Generalized to the eye and translated into human perception, it is the range of lightness between what is seen as pure black (no lightness) and what is seen as pure white (blinding lightness). Final results after full editings using only filmic (with chroma preservation) and color balance modulesĮven though HDR is a big thing right now in the LED screen industry, and this term is wildly used to describe anything for marketing purposes, it is useful to recall what it is. The dynamic range is the interval of measurement between the sensor detection level (ground level) and its saturation level (ceiling level).Comparison with other darktable’s tonemapping methods.The beginning of this article is mostly directed toward a general audience, until the section Controls, which provides a complete manual showing how to use the new filmic module. The next sections are mostly directed at scientists and technical audience. ![]() After having used it for 7 years, I begun to develop in it 3 months ago. This article shows my work and results to improve the HDR-scenes handling in darktable, in a fashion that allows better color preservation for portrait photography. Darktable is an open-source software for raw photographs management and processing developped since 2009 for Linux desktops. Since then, it has been ported on Mac OS and Windows 7, 8, 10.
