In this image, the blur of people moving around in the crowd makes it look interesting, but it is also focusing on particular people who are standing, walking, moving in what looks like a busy area. A slow shutter speed is used in this image.
Image by an Iraqi artist taken in an orphanage. This little girl has never seen her mother, so she drew a mom on the ground and fell asleep with her. Such a sad picture. I can only imagine the heartbreak children like this feel.
