Documenting the effects of climate change first hand over the past eight years, Camille Seaman fears we may be on the road to the last iceberg. Photographing the enormous frozen floats at both poles for the past eight years, the Californian adventurer has seen the receding ice shelves and experienced the changing warmer weather. Feeling that her intimate and emotional work documents a snapshot of history, Camille presents her series “The Last Iceberg” as a study of what she sees as the personality of each huge iceberg. Drawing parallels with the famous novel, “The Last of the Mohicans”, Camille, 42, wonders whether these unique, almost alien natural features will become a thing of the past or part of nature's renewal process.

“The Daleks are a fictional extraterrestrial race of genetically manipulated mutants from the British science fiction television series Doctor Who. Various storylines portray them as having had every emotion removed except hate, leaving them with a desire to purge the Universe of all non-Dalek life. Collectively they are the greatest enemies of the series' protagonist, the Time Lord known as the Doctor. Their famous catchphrase is “Exterminate!”, with each syllable individually synthesised in a frantic electronic voice” – Wikipedia
