When it comes to image editors, Adobe Photoshop remains the gold standard for professionals. But for students, the amateur, or anyone starting their career, the $700 price tag (or even ~$200 with a student discount) is likely prohibitive. There are cheaper apps available, such as Acorn and Pixelmator, but they offer far fewer features.
Luckily, there’s GIMP (GNU Image Manipulation Program) a completely free and open source image editor that nearly matches Photoshop’s versatility. It’s long been available on the Mac if you had X11 installed, but never looked the part of a high quality Mac app. That’s all changed with the latest 2.8.2 release of Gimp, which shipped as a fully native Mac app. That’s what prompted us to take a closer look at the most popular Photoshop alternate.
