Dan Martensen's fashion and portrait photographs have an aesthetic of natural beauty. Often photographing on location and in rural environments, Martensen's relaxed and collaborative approach creates images of genuine ease and spontaneity. Martensen studied photography at RISD and brings the qualities of an observational photographer to his commercial work, finding meaning within the scenarios that unfold in front of his camera.

Dan’s book, "Wolves Like Us", was published by Damiani in fall 2015 to much acclaim, a five-year photographic collaboration with the seven Angulo siblings, the subjects of the feature-length documentary film The Wolfpack. The work was also exhibited at the reopening of Deitch Gallery in New York.

For his first edition, a selection of sixty photographs was published in "Photographs from the American Southwest", designed by Berger + Wild. Dan travelled across America, principally in the states of the South West, photographing what he saw.

On his travels, he sought the visual paradoxes and embedded histories of the region, taking cues and his creative departure from the work of the legendary chroniclers of the American vernacular; William Eggleston, Joel Sternfeld and Stephen Shore.
