Ah, GIMP. Any creative who's ever balked at Adobe's pricing will have a fondness for the ridiculously named GNU Image Manipulation Program. GIMP for short, the free, open-source program has endured as one of the best Photoshop alternatives for those who want to edit images without forking out for a hefty monthly subscription fee.
The software was built as a class project in 1995 by Spencer Kimball and Peter Mattis. Originally for Unix-based systems, it now runs on Windows and Mac as well as GNU/Linux and offers a full array of painting, colour correction, cloning, selection and enhancement tools. It even has AI capabilities through third-party plugins and extensions.
