Photivo is a free and open source photo processor. It handles your RAW files as well as your bitmap files in a non-destructive 16 bit processing pipe with gimp workflow integration and batch mode.

Photivo tries to provide the best algorithms available; even if this implies some redundancy. So, to my knowledge, it offers the most flexible and powerful denoise, sharpen and local contrast (fake HDR) algorithms in the open source world. (If not, let's port them ;-)) Although, to get the desired results, there may be a quite steep learning curve ;-).

Photivo is just a developer, no manager and no “Gimp”. It is intended to be used in a workflow together with digiKam/F-Spot/Shotwell and Gimp. It needs a quite strong computer and is not aimed at beginners.

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)
* Demosaicing: Bilinear, VNG, VNG4, PPG, AHD, DCB, mod. AHD, VCD, LMMSE, AMaZE (needs work!).
* RGB, R, G, B, L*, a*, b*, Texture, Detail, 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 wavlets, GreyCStoration, Wavelet, Masked bilateral, Pyramid).
* Adaptive saturation.
* Film grain simulation.
* Black and white conversion.
* (Split) Toning.
* Cross processing.
* Gradual overlay (like Cokin filters).
* Vignetting.
* Softglow / Orton.
* Texture overlay (external texture)
* Batch mode.

Install Photivo in ubuntu using PPA

Open the terminal and run the following commands

sudo add-apt-repository ppa:dhor/myway

    I think it would be great if work started on a modular system whereby the equivalent of Adobe’s Lightroom could be created in open source by using and adapting the relevant engines (organisation, develop, print, etc) from various open source photo applications already in existence. Open source has some great software but I wouldn’t want to try moving from LR to a system involving multiple separate applications.

    I’ve been using photivo for some time and leaving aside a few quirks due mostly to not enough manpower it’s the best in its class for linux.

    I’ve been using Photivo for a while. It is a great package and due to the power of its filters, has dramatically reduced my need to do subsequent, post RAW processing in GIMP.

    Further, the creator Mark, and contributor Brother John, are very available and responsive to feedback and suggestions for enhancements.

    If anyone wants to give it a try, you can find it at http://photivo.org/photivo/start
