The histogram display as well as the browser can be configured: by default, the displayed values take into account the "Output profile".The reader shall preferably have minimal knowledges about color management : matrix triplet, RGB, XYZ, Lab, color space, primaries and colorimetric profile.
RawTherapee automatically detects the system profile, however you can enter the screen icc filename in « Preference/ Color Management / Monitor Profile ». the DTP94 probe I own, and for which it doesn't exist any more drivers for Windows) give very good results the processing time is quite long (about an hour). Under Windows, MacOS or Linux, a software like DispalGUI from Argyll, combined with a probe of quality, even old (e.g. The created profile is for the monitor only and must never, in any case, be used either as input profile or output profile. However, it is recommended to calibrate the screens with one of the many products in the market: colorimetric probe plud software. This document doesn't aim to deal with the whole colorimetry aspects that aren't specific to RawTherapee, like for instance:. More over it does not take into account possible malfunctioning (bugs) still unsolved ! Note: This document only deals with RawTherapee 4 and computing with real numbers, and not RawTherapee 3. To explain the use of some functions that may look obscure to newcomers. To explain the main steps principles in order to allow the user to be able to weight what is at stake.ģ. To summarize the raw file processing pipeline from a colorimetry point of view and to highlight key points and gapsĢ. 
This document aims at several objectives about colorimetry:ġ. 1.5 What happens when we are in a "Working Profile" or when we change of "Working Profile" or the settings?.1.4 Work in the color space chosen by the user (working space "Working Profile").1.3 rgb => RGB conversion - Working space "Working Profile".1.2.3.9 Illuminants Diagrams and Color Rendering Index (CRI).1.2.3.6 "Blackbody" illuminant and "A: tungsten".1.2.3.4 Colored object – illuminant – observer.1.2.2 ICC input profiles : elaboration, use, gaps.1.2.1 Read the raw file and use its data.1.2 Initial raw processing before RGB conversion.
