What is the origin of the unique lakes in the Volcanic Eifel region of Germany? In short, they were created from an explosion of water vapour when lava from a hot spot under the region met with groundwater thousands of years ago. The explosion created a round funnel, or crater, with earthen walls, which was later filled with rainwater. That is why the water is really clear and has rather good visibility.

In underwater photography, "scale" can mean a couple of things: how big or small a thing is or the myriad of tiny plates on the skin of a fish. We asked our contributors what their favorite underwater photos were that showed scale. And playing on the pun, they came back with a creative mix of macro, wide-angle and close-up abstract images.

UW Photo: Compositing

We take photographs for different reasons: to identify the sea life we find, for the sheer pleasure of making images, or perhaps as a method of personal expression. It is the latter, personal expression, that leads us to the creation of art. John A. Ares discusses the creative use of compositing in postproduction.

We asked our contributors what their favorite underwater photos taken with their camera angled upward were, and they returned with a variety of subjects captured while looking up... from delicate macro marine life to floating jellyfish, from majestic manta rays to divers and even birds.
