I'm always interested in how two or more seemingly unrealted images can work together - sometimes by accident, and sometimes through careful editing.
Watch this beautifully edited video from the World Wildlife Fund. Watch it again, using the pause button, to figure out why each brief segment "works" - is it the composition? colors? focal point? perspective? motion? all of these at the same time, or only one or two together? How would you begin to create a similar collection of images? Do you think it relays the message of "connected-ness"?
