The Private Collection is composed of Gray’s most exclusive and extreme shoots; journey to the peaks of Mount Otemanu in Bora Bora, the glaciers of Antarctica, the rugged and beautiful desert land of Namibia and to Bhutan, the land of happiness. Gray considers these series of images to be some of his most difficult considering the lengths that were taken to achieve them, which is also why they are some of the most rewarding and awe-inspiring.
