secretive

Over the years, photojournalist Anthony S. Karen has gained access to some of the most secretive groups in the world. From Skinheads, to the Westboro Baptist Church, to the Vodou societies of NYC and Haiti, he prides himself on earning his elusive subjects' trust, and a candid look into their lives along with it.

One of his longest running projects involves photographing the modern-day Ku Klux Klan, resulting in photos that give us an intimate glance inside a world few ever get to see.

Photo-sharing apps run the gamut between the hyper-social (ala Instagram: like, comment and share to your heart's content) and the secretive (ala Snapchat: this photo will self-destruct in 3 ... 2 ... ). Ustwo's new app Rando falls somewhere in that latter category, because while you can share photos with Rando, you have no idea who you're sharing them with, or who is sharing them with you -- and forget about likes, comments and favorites.
