I found these photographs are really amazing. Recently, I am keen in multiple exposure. After searching in Internet, I found these amazing works. These all took by Marcus Yam. Before seeing his sketches, I did not know how difficult is it. Marcus Yam said that every time before he going to shoot, he will plan his images. I have tried to shoot use double exposure, but they look not very nice. I think that because I just use that camera technic, never thinking about the meaning why I did this.
So now I knew that "Photograph" not just using your camera to shoot something or someone, rather, we should think about the whole thing before shooting.
