Free Gems

Right then. On the Internet, there are many software both free and otherwise and some of them are gems. And this here page list out the free/open source graphics programs that I know of  (to date):

Photo editing/raster/bitmap graphics:

• Paint.net
• Pixia
• GiMP
• Irfan View
• Photoscape*

Vector graphics:

• Inkscape

3D Graphics

• SketchUp
• Blender

Do note that each of these links open up a new tab/window.
