Image via WikipediaTechNewsWorld has an informative post aboit GIMP, the open-source alternative to Photoshop. It rightly points out that GIMP is not lightweight when it comes to features and can compete with many photo-editors that cost plenty of money, whilst of course, GIMP is available free for most platforms.
GIMP is Linux Speak for GNU Image Manipulation Program. However, its available for Windows and Mac, as well as Linux and is well worth downloading and getting familiar with.
GIMP does, however, come with a learning curve. For anyone unfamiliar with photo manipulation packages in general, any of the top-notch photo editing programs will be intimidating at first. Likewise GIMP gives even those with a working knowledge of graphics editing a bit of a challenge.
One reason for this is the sheer number of options available in the drop-down menus. You can spend an hour or two playing around with the choices found in the various menus available, of which there are plenty.
