GIMPshop is a modification of the free/open source GNU Image Manipulation Program (GIMP), intended to replicate the feel of Adobe Photoshop. Its primary purpose is to make users of Photoshop feel comfortable using GIMP. It shares all GIMP's advantages, including the long feature list and customisability, while addressing some common criticisms regarding the program's interface: GIMPshop modifies the menu structure to closely match Photoshop's, adjusts the program's terminology to match Adobe's, and, in the Windows version, uses a plugin called 'Deweirdifier' to combine the application's numerous windows in a similar manner to the MDI system used by most Windows graphics packages. While GIMPshop does not support Photoshop plugins, all GIMP's own plugins, filters, brushes, etc. remain available
There's no question that Adobe Photoshop is excellent image editing software. But for those of us that can't afford up to seven hundred dollars or more to buy it, we now have the same image manipulation power at our fingertips as the high-priced, closed-source programs. In fact, with the release of 2.8, Gimpshop has become prefered software for photo & image editing among more professionals than ever. Layers, channels, masks, filters, levels, advanced pattern matching—the remarkable feature list of Gimp is equal to Photoshop in every way except one: the price. Restore, touch up and manipulate photos, create complex animations, or just use Gimpshop as a simple paint program. The only limit is your imagination.
