You might recognize Aussie photographer Luke Austin from his mega-popular Instagram account in which, like his new "Beau Book," he photographs strangers in little to no clothing. (Rough life, eh?)

In "Beau Book," a new photobook out today, Austin's finally unleashing two years of photographs featuring over 130+ guys shot during his travels across America, Europe and Australia, where he met men that he had connected with on Instagram for a peek, as he puts it, "behind the filter."

So how did it come together? In 2012, Austin broke up with his then-boyfriend and decided to bury his pain and go on a six month adventure around the world. "A month before leaving, I decided to take my camera and photograph all these men that I'd been chatting with on Instagram and try and make a book of it," Austin tells NewNowNext.

Most of these portraits were taken the day he met these guys. "I knew them all from the Internet, but meeting them they were strangers. None of the men photographed are professional models."

As for the snapping full frontal nude shots of complete strangers: "Everyone always asks me this: how hard it must be to get someone naked and stay professional, and I don't know, when I'm in that photographer mode and trying to find perfect lighting in someone's apartment, I'm literally not even thinking about it. Then why I get home and the images are on my computer and I'm editing I'll think, 'wow, that was really hot.'"
