I am an amateur photographer, or let me say I am trying to become a photographer. I've been reading about a lot of photoblogs and I came across HongKong's Photoblog. Of course it's in Chinese but most videos and pictures are pretty understandable. Maybe there's something about art that makes you understand even if the description is written on a different language/. The art is called BOKEH, you don't need to buy, you can make one on your own and you can do it on any camera. Here's a video of it.
