Photivo, handle RAW on Linux

Photivo is a free and open source (GPL3) photo processor. It handles your RAW files as well as your bitmap files (TIFF, JPEG, BMP, PNG and many more) in a non-destructive 16 bit processing pipe with gimp workflow integration and batch mode.

Features

  • 16-bit internal processing, color managed with LCMS2.
  • Gimp workflow integration (import and export)
  • Works with RAWs and Bitmaps (8 bit bitmaps are transformed and processed with 16 bit, which usually gives better results).
  • CA correction, Green equilibration, line denoise, badpixel reduction, wavelet denoise, median filters on RAW data.
  • Perspective correction (tilt and turn), distorsion and geometry (also defish) correction
  • Demosaicing: Bilinear, VNG, VNG4, PPG, AHD, DCB, mod. AHD, VCD, LMMSE, AMaZE (needs work!).
  • RGB, R, G, B, L*, a*, b*, Texture, Detail, Denoise, Hue, Saturation, L* by Hue, Base curve.
  • Tonemapping (Reinhard 05 (RGB Brighten), Fattal et al. (Dynamic range compress)).
  • Several local contrast filters (HiRaLoAm (Local contrast), texture contrast, local contrast stretch).
  • Sharpen (Edge avoiding wavlets, USM, Highpass, Inverse diffusion, Wiener filter, Gradient sharpen).
  • Denoise, seperately on Luminance and Color (Edge avoiding wavelets, GreyCStoration, Wavelet, Masked bilateral, Pyramid) and via a hue or luminance sensitive denoise curve.
  • Adaptive saturation.
  • Film grain simulation.
  • Black and white conversion.
  • (Split) Toning.
  • Cross processing.
  • Gradual overlay (like Cokin(R) GND filters).
  • Vignetting.
  • Softglow / Orton.
  • Texture overlay (external texture)
  • Fake tilt/shift, toy effect
  • Batch mode
  • Translations: Dutch, French, German, Italian and Russian.
