I am newbie to graphics design world. Recently I have introduced about "clipping path". And it seems interesting to me. and I have already seen a tutorial about it. But I don't have Adobe Photoshop. I went to their site but the software wasn't free. Is there any other free software like Adobe Photoshop where I can learn & practice clipping path?

Tutorial looks good. Because there is picture with description for better understand. But unfortunately i don't have Adobe Photoshop software.

Is there anyone who can help me out? Thanks in advance.
