Raw Therapee is a free RAW converter and digital photo processing software.
- Selectable high performance demosaicing algorithms (EAHD and HPHD and VNG-4).
Compare them on this comparison page. - Using DCRaw 8.82/1.398 for decoding RAW images
- Image post processing in 16 bit / channel mode
- Exposure control in RGB space
- Auto exposure with adjustable clipping point / Exposure compensation / Shadow and highight compression / Contrast adjustment, curve editor
- White balance adjustment in RGB space
- With in-camera, automatic and spot white balance options / Temperature/Green tint fine tuning
- Highlight Recovery
- Shadows/Highlights control in RGB space
- Basic Luminance curve tool to modify the luminance channel in CIELab color space
- Brightness / Contrast adjustment, curve editor
- USM sharpening applied on the CIELab luminance channel
- Classical USM parameters (Radius, Amount, Threshold) / Option to avoid noise amplification / Sharpening halo control
- Optional RL Deconvolution based sharpening for even better sharpening results
- Color shift control in CIELab color space
- Allows color shift by shifting the CIELab "a" and "b" channels
- 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
- Luminance denoising algorithm applied on the CIELab luminance channel
- Edge sensitive method to preserve as much details as possible
- Color denoising tool applied on the CIELab "a" and "b" channels
- Classical gaussian blur or edge sensitive bluring of the color channels
- Fast switching between different postprocessing profiles
- Image flipping horizontally or vertically, rotation by 90 degrees clockwise or counter clockwise
