A photographic celebration of one of nature's most majestic creatures.

Over a five-year period, photographer and filmmaker Jem Cresswell took more than 11 000 images of one of nature's largest mammals the humpback whale in Tongan waters.

In Giants, Cresswell selects the most striking of these images to document the awe-inspiring behaviours of the humpback whale in a powerful combination of photography and storytelling.
