Adobe Photoshop is a great product. I have been using it since 2003 and I simply love its functionality and ease of use. If there is anything to complaint about, then it has to be the high cost (US$649) involved in buying the software. For those who can’t afford Photoshop, here is a list of the 5 great free alternative to Photoshop.
There is no doubt that GIMP is the closest alternative to Photoshop. GIMP is used by many professionals and contains most of the functions in Photoshop. While some people dislike the interface and find it hard to use, there are still many others who love this open source software. You can find a huge user community supporting this product. Many Linux distributions have also used GIMP as the default image editing program. GIMP is available for Linux, Windows and Mac OSX.
