GIMP lovers may disagree, but the world’s needed a GTK photo editor with an easy-to-understand interface for a while. Featuring layers, various effects and good old fashioned editing functions, Pinta is the photo editor missing on Linux systems, as well as Windows and OS X. Think Paint.net, but cross-platform.
But even if you don’t use Linux, you just might find Pinta to be your new favorite free image editor. It’s fast, functional and gets the job done. If you’ve used Paint.net, or even Photoshop before, you’ll probably not have any trouble finding anything. But if you haven’t, consider Pinta a fantastic introduction to what photo editing software can do that’s not too cofusing to use.
