From time to time I have the need of an editor for my photos. A very
in depth solution is the GNU Image Manipulation Program (GIMP). The development of GIMP began in 1995 and it still has a very active development community.
I like GIMP as it is cross platform – OS X, Windows several different Linux distributions, Solaris, and BSD. GIMP is an ideal program for photo retouching, image composition and image authoring. Image editing tools include filters and brushes, transformations, selection, and layers and masking. GIMP includes ‘smart’ tools such as a clone
tool, a healing brush, a perspective clone tool, blur and sharpen tools, and dodge and burn tools.
GIMP has a customizable User Interface and supports the common image file formats: JPEG, GIF, PNG and TIFF. GIMP also accepts a wide range of plugins and scripts developed by the users. While GIMP cannot do everything Photoshop can, it can do many of the most common tasks.
There is very good documentation in several languages for GIMP and nearly 50 tutorials available from the GIMP web site. If you need more than the on-line documentation provides, there have been several books published on GIMP and how to use it.
If you find GIMP to be of interest, you should check out Starter Guide to GIMP – Free Mac Image Editor
