![]() ![]() You can choose predefined values such as 'standard g 2.2', 'sRGB g=2.4 s=12.92' or build a custom TRC. The TRC is essentially a curve that transforms the initial or input values of the image into values that will be recorded in the output image. Operation of the algorithm Tone Reproduction Curve In the ICC profile generator, you specify the location of the primary colors on the 1931 CIE xy chromaticity diagram using the xy coordinates. The three primary colors - Red, Green, Blue - are additive and form the basis of all other colors. To make the profiles you generate available for use in RawTherapee, save them to the "directory containing color profiles" as specified in Preferences > Color Management. The code and the basic principles are similar to those used for Abstract profiles UsageĪccess this module via the ICC Profile Creator button located either in the bottom-left or top-right of the RawTherapee window. You can generate profiles in accordance with ICC versions 2 and 4, and in both cases you can use custom primaries and modify the illuminant as well as the tone reproduction curve (TRC). the primary colors, the tone reproduction curve, and the white point (illuminant). the A2B or B2A tags, but you can adjust those that are important for a photographer i.e. You cannot adjust all the parameters of an ICC profile with this tool, e.g. RawTherapee can generate output, screen or custom working profiles using the XYZ matrix generated for Custom profiles You can use standard presets as well as custom values. Refer to RawPedia for a detailed explanation of how to get the necessary dependencies and how to compile RawTherapee.The ICC Profile Creator allows you to generate your own ICC profiles. RawTherapee is not aimed at being an inclusive all-in-one program, and the open-source community is sufficiently developed by now to offer all those peripheral features in other specialized software. Professionals may use RawTherapee as well while enjoying complete freedom, but will probably lack some peripheral features such as Digital Asset Management, printing, uploading, etc. ![]() Knowledge in color science is not compulsory, but it is recommended that you are eager to learn and ready to read our documentation ( RawPedia) as well as look up basic concepts which lie outside the scope of RawPedia, such as color balance, elsewhere. The target audience ranges from enthusiast newcomers who wish to broaden their understanding of how digital imaging works to semi-professional photographers. ![]() RawTherapee is designed for developing raw files from a broad range of digital cameras, as well as HDR DNG files and non-raw image formats ( JPEG, TIFF and PNG). It is notable for the advanced control it gives the user over the demosaicing and development process. It uses a patched version of dcraw for reading raw files, with an in-house solution which adds the highest quality support for certain camera models unsupported by dcraw and enhances the accuracy of certain raw files already supported by dcraw. It is written mostly in C++ using a GTK+ front-end. RawTherapee is a powerful, cross-platform raw photo processing program, released as libre software under the GNU General Public License Version 3. ![]()
