I surely missed something even after reading the french rawpedia. So Ideally the only parameter needed is a luminance curve or cursors to modulate the density of the transmission mask. where is the luminance curve which modulates the transmission mask?.ColorAppearance, ColorToning, Retinex, ToneCurve, Wavelet. In order to obtain the desired dehaze effect, the transmission mask can be modified with a luminance curve ( S shape for example) to increase or decrease foreground and background. Fossies Dox: rawtherapee-5.8.tar.xz (unofficial and yet experimental doxygen-generated. Looks like you are editing a jpeg, so the retinex tool should be disabled. Retinex only works when editing raw image files. why the transmission mask are colorful? However, the Retinex module refused to expand, irrespective of resolution (but that probably has nothing to do with icons ).Why as I just want to display an existing mask, the processing pipeline is replayed?.To display it in Retinex, I click on “process” and I have the choice between two transmission masks. This map should be a kind of representation of atmosphere thickness as the mask provided in same link above (not in same dimension) Second step : I try to display the transmission map.
My first step is so to enable Retinex : terrible result with a pink sky.

Other features include automatic chroma noise reduction, manual luminance noise reduction using sliders and curves, post-resize sharpening, Luminance and Perceptual tone curve modes. The main page of ART is quite identical to RawTherapee, the differences are in the modules.
#Retinex rawtherapee how to
My aim is not to find the optimal result but only how to dehaze with Retinex, getting an acceptable starting point. The updated version 5 of RawTherapee introduces new features, two of which included wavelets and retinex tools. Color constancy is a phenomenon in which the human visual system adapts to. It is designed for developing raw files from a broad range of digital cameras and targeted at users ranging from enthusiast newcomers who wish to broaden their understanding of how digital imaging works to professional photographers. Retinex theory tries to explain how our visual system works for color changes and perceives object/scene color despite changes in illumination. RawTherapee is a powerful, cross-platform raw photo processing system, released as Free Software ( GPLv3 ). This can be by scale, width height or bounding box. The Specify option allows you to choose how to resize the image. For the method, select Lanczos, this is recommended by RawTherapee. Select cropped if you have previously cropped the image.
#Retinex rawtherapee full
Perhaps I should open a new thread? let me know Retinex Color Theory first proposed by Edwin Land in 1964 aimed to explain the color constancy of the Human Visual System. The first drop-down asks whether you wish to apply the resize to the cropped or full image.
