This is very good, since the chroma noise looks very unnatural and needs a rather energetic denoising, while the luminance noise is more natural (film-like, I for one, like it more than an over-denoised image) and you can leave quite a bit of it on your image. Promise.ĭenoising allows to separate chroma noise (patches of the wrong colors) from luminance noise (dark / light pixels). If I ever manage to turn a bad picture into a masterpiece via Luminance Curve rather than Exposure Curve, I’ll blog about it. The Luminance Curve is very similar to the exposure correction, but it modifies the luminance channel of the CIELAB space rather than working directly in RGB – thanks to the manual again. The Color Shift allows color correction on the green-magenta and blue-yellow axis – I would say that this type of correction should be done in the white balance tool, so I find very little use for this tool. Sharpening is a classic Unsharp Mask Tool.Ĭolor boost (according to the manual) amplifies the A and B channels of the CIELAB profile – well, well… play with it: it boosts your colors nicely but don’t over use it. The Shadows/Highlight tool allows to selectively adjust the dark or light zones of an image without touching the rest. One interesting bit is the Highlight Recovery which allows to retrieve some detail in near white burnt clipped zones of an image. We find here the ususal white balance and exposure (with curves) tools. Refer to RawTherapee’s users manual for all details. Plenty of things to play with here – so I will not detail each of them. Now this is the part that interests us most. There is also a “history” browser which I don’t show here and can be used as an undo mechanism.Īt the top of the main image region, you have a couple of “most often used” function: white balance picker, cropping, rotation (same tool as RawStudio), orientation and high / low light warning.Īt the bottom, you find the zoom function as well as a magnifier which allows you to check a part of the image at 100%: Nothing fancy here: your main picture, thumbnails, a directory navigator, plenty of tools on the right and a histogram. RawTherapee is available for Linux, Windows and Mac, but there is no 64bits version.Īlthough RawTherapee is a one-man work, it offers high quality 16bits / channel processing and is color managed, so well suited for high quality RAW processing. Although it is not Open Source, it is available for free – but donation for its development is encouraged. Unless you are very adventurous, you’ll want to download the older version and simply keep an eye on for version 3.0.After the Open Source RawStudio, after seeing that LightZone is no longer available for Linux, there is another workflow oriented RAW processing software available for Linux: RawTherapee ( web). A newer version is still in the works, as of January 2011, with source code available for compiling unstable versions for Windows, OS X, and Linux. The most current version is of Raw Therapee is 2.4.1, and even though it is several years old, it is still an excellent solution for the budget-minded photographer.
