One of my new goals this year is to become an expert at many of the Open Source tools available. GIMP is a photo editing application rivaling Photoshop. GIMP used to be very difficult to use and the interface was not very user friendly. A lot has changed with the newer GIMP. I purchased a copy of Adobe’s Creative Suite 1 that had Photoshop as a part of the suite years ago. I downloaded a copy of Photoshop for Adobe CS3 but I have deleted both copies from my computer. I intend to use GIMP for all my photo and graphics needs. Here I will post useful resources and tutorials for GIMP.
