rawtherapee -- raw image processor.
<a href="http://www.rawtherapee.com/?mitem=3&artid=47">Download RT v3.0 alpha 1:
Rawtherapee is a <a class="zem_slink freebase/en/raw_image_format" title="Raw image format" rel="wikipedia" href="http://en.wikipedia.org/wiki/Raw_image_format">RAW image processing software. It gives full control over many parameters to enhance the raw picture before finally exporting it to some common <a class="zem_slink freebase/en/image_processing" title="Image processing" rel="wikipedia" href="http://en.wikipedia.org/wiki/Image_processing">image format.
You can also install the version ”3.0” from the fedora repo using the command:
sudo yum install rawtherapee
Main features :
- Selectable high performance demosaicing algorithms (EAHD and HPHD and VNG-4).
Compare them on this comparison page. - Using <a class="zem_slink freebase/en/dcraw" title="Dcraw" rel="homepage" href="http://www.cybercom.net/%7Edcoffin/dcraw/">DCRaw 8.82/1.398 for decoding RAW images
- Image post processing in 16 bit / channel mode
o Exposure control in <a class="zem_slink freebase/en/rgb_color_model" title="RGB color model" rel="wikipedia" href="http://en.wikipedia.org/wiki/RGB_color_model">RGB space
- Auto exposure with adjustable clipping point / Exposure compensation / Shadow and highight compression / Contrast adjustment, curve editor
o White balance adjustment in RGB space - With in-camera, automatic and spot white balance options / Temperature/Green tint fine tuning
o Highlight Recovery
o Shadows/Highlights control in RGB space
o Basic Luminance curve tool to modify the luminance channel in CIELab <a class="zem_slink freebase/en/color_space" title="Color space" rel="wikipedia" href="http://en.wikipedia.org/wiki/Color_space">color space - Brightness / Contrast adjustment, curve editor
o USM sharpening applied on the CIELab luminance channel - Classical USM parameters (Radius, Amount, Threshold) / Option to avoid noise amplification / Sharpening halo control
o Optional RL Deconvolution based sharpening for even better sharpening results
o Color shift control in CIELab color space - Allows color shift by shifting the CIELab ”a” and ”b” channels
o Color booster applied on the CIELab ”a” and ”b” channels - Amplifies color channels ”a” and ”b” together or separately / Avoids color overamplification in high chrominance areas / Option to avoid clipping caused by too high color boosting
o Luminance denoising algorithm applied on the CIELab luminance channel - Edge sensitive method to preserve as much details as possible
o Color denoising tool applied on the CIELab ”a” and ”b” channels - Classical gaussian blur or edge sensitive bluring of the color channels
o Fast switching between different postprocessing profiles
o Image flipping horizontally or vertically, rotation by 90 degrees clockwise or counter clockwise
o Arbitrary image rotation (straightening tool) - with fill function or automatic crop
o Simple lens distortion correction
o Crop tool
o <a class="zem_slink freebase/en/chromatic_aberration" title="Chromatic aberration" rel="wikipedia" href="http://en.wikipedia.org/wiki/Chromatic_aberration">Chromatic Aberration correction tool
o Channel Mixer for Red, Green and Blue channels
o C/A Correction
o Vignetting Correction
- ICC based color management
- Change History with bookmarks to support before/after checking
- Output options:
o Supported file <a class="zem_slink freebase/en/image_file_formats" title="Image file formats" rel="wikipedia" href="http://en.wikipedia.org/wiki/Image_file_formats">formats:

o Image ouput size could be set
o EXIF data is preserved in JPEG output (except crw files)
o Output directory and automatic file naming highly customizable
- File browsing with thumbnails
- Localization supported (utf8 language file):
already included languages are: czech, deutsch, english, espanol, italian, latvian, magyar, nederlands, polish, russian, slovak, swedish
