Since I find a Photoshop license to be expensive I use software like Gimp or Inkscape for my graphic design needs. They perform almost the same and you can even save your files in a format that's understood by the Adobe line of software. This is needed since most clients need the source files in the adobe formats. Another example would be software like OpenOffice. It works well for my needs and I don't need to purchase Microsoft Office. What other free or cheap software can you recommend?
