Founded by Jake Lodwick, the guy behind Vimeo and CollegeHumor, the company recently launched Thinglist, a want to do list, and Keezy, a clever beatboxing app for iPhone. Today, its launching its third product of 2013: Exposure, a subscription web service for sharing photo sets. Exposure is a lot like Medium, the minimal, highbrow blogging platform created by Twitter co-founder Ev Williams, but for photos — so of course, Exposure creators Luke Beard and Kyle Bragger call their photo sets narratives. But true to its name, Exposure does shed more light on your photos than a simple photo set on Tumblr or 500px.
