About Photivo Photivo is a free and open source (GPL3) 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. Processed with Photivo Basically it’s an image processing assembly line. You set the parameters, throw your RAW file in on top, wait for a moment and catch your image when it falls out of the machine. Today I give it a try and rescue an image of a kite with it. It’s an impressive tool with a quite unique but understandable user interface. I’ll explore this further, perhaps it will enter my workflow. The companion file contains both used RAW files and all the setting files created by Photivo.
