Open-source photo editor with support for RAW
Photivo is a free photo editor that's different from any others you may have tried so far. It works not only with your regular bitmap files (JPG, BMP and so on) but also with RAW images, in a non-destructive editing procedure.
Don't be mistaken here: Photivo is no free Photoshop, and doesn't let you view and manage photos like a traditional photo viewer. It's not aimed at beginners either, but rather at users who take photography as a serious hobby and are used to dealing with RAW files.
That said, the truth is that Photivo is a great tool for digital photo developing. It includes a plethora of options, filters and special effects that help you make each shot unique, without losing the quality of the original picture. The program may have a steep learning curve, but it’s totally worth it.
On the downside, Photivo didn't seem the quickest editor in the world at all. Any small change took a few seconds to show up in the preview image – especially if you’re not using a high-spec system.
Photivo is an open-source powerful photo editor that works both with standard bitmap images and RAW photos.
