I'm learning graphics design on my own. My greatest challenge is giving a polished look to my pictures and images. I will forever remain grateful to anyone that can help me with good tutorial materials for this purpose. Am willing to pay for it if need be. Thanks.

learning without video tutorial will be hard for you. Am a beginner but am improving daily by learning thru You tube.You can start with beginners tutorial on adobe cs6 and then to others.

If you want to learn some basics of photography editing and other important tips and aspects of it, you should take online courses and lessons. It is very important for every beginner photographer in my opinion. When I was a beginner I took some courses from http://www.howtophoto.com and, I learned almost everything I know from there. Very helpful, indeed
