I have been using CS6 since 2 years and and but still everyday I learn something new while editing my pics. It has beautiful features in it.
I learnt many of the basic tools uses through YouTube. It has become very easy to edit pictures and make collage pictures for my friends birthday. It’s luminous effect is cool.
Adobe is best known for its many of the application softwares. So I strongly recommend you to use CS6. It gives you a professional like features in editing beautiful images.
