Gimp! The best known open source software for photo editing. This has been giving Photoshop headache since ever it was launched first.Many people who are so used to Photoshop bash up Gimp. But Since I’ve tried it myself for sometime, I found it rather refreshing. Here are some excellent Brushes I had bookmarked some time ago and thought you guys might find them useful too. Most of the Gimp brushes are converted from Photoshop Brushes but they’re still excellent and must haves ifyou are a GIMP user.
