GIMP - graphics editor, free replacement of photoshop
With the worldwide popularity of digital photography, photo editing software is more important than ever before. GIMP, also known as the GNU Image Manipulation Program is one of those applications and its main difference compared to the more popular Adobe Photoshop is that it is 100% free. This makes GIMP perfect for those of us who are on a budget but still want a commercial grade photo editing software.
One of the most powerful general-purpose image editors around, the upgrades make the GNU Image Manipulation Program eminently comparable to Photoshop. Older features include channels, layers and masks, filters and effects, tabbed palettes, editable text tools, perspective clone, improved printing, and color operations such as levels. New improvements include GEGL integration for 32-bit color support, dynamic brushes, and more options for the free select tool. It even has regex-based pattern matching for power users.
The application provides professional tools that can stand against the big boys without the hefty price tag. Even the installation process has gotten simpler, with no need to download and install the GTX Runtime Environment separately. Extremely powerful and easy to work with, GIMP is ideal for both amateur and pro photographers, Web designers, or anyone who wants to create and edit professional-quality digital images on a budget
