Techie Tip of the Week: gimp.org

Friday, September 2nd, 2011

Did you know that there is a free, open source, fully featured alternative to Photoshop?

The Gnu Image Manipulation Program is a fully-featured, sophisticated desktop-based image editing and manipulation tool. In many ways, the GIMP rivals and even exceeds the capabilities of Photoshop (especially if you download and install the many and varied plugins for GIMP).

The GIMP is available for Windows, Mac, and Linux.

More information, including download, and installation instructions is found on the GIMP website:
http://www.gimp.org

To enhance functionality in the GIMP, visit the Plug-in Registry:
http://registry.gimp.org/

For documentation on using GIMP visit the docs section:
http://www.gimp.org/docs/

My favorite GIMP plugins:

Liquid Rescale: http://registry.gimp.org/node/144

  • This plugin performs content-aware scaling¬† in GIMP (and preceded Photoshop’s ability to do so by at least a year!)
  • Video Example of Liquid Rescale:¬†http://bit.ly/ohiXi0

Resynthesizer: http://registry.gimp.org/node/25219

  • This plugin performs content-aware fill in GIMP (and preceded Photoshop’s ability to do so by years!)
