Raw Therapee is cross-platform RAW image file processing program. It compares well with its more expensive commercial counterparts such as Adobe Photoshop, Lightroom, Bibble Pro, etc., but its user interface has a steeper learning curve.
Raw Therapee lets you apply color correction, image sharpening, and retouching to your RAW image files in a non-destructive way. Its image sharpening algorithms appear to be superior to some of its commercial peers, and its color correction features lets you make adjustments to a deeper level than similar programs.
Beyond color correction, RawTherapee also provides other in-depth options ror RAW file corrections. This includes things such as pre-processing, pattern noise and chromatic aberration correction. Batch editing is also supported within the File Browser tab.
