If You Leave is an ongoing series of work that accepts submissions from artists all over. The collection of submissions have been published into two volumes. There is a flicker, facebook, and (obviously) tumblr... that continues to post work that is loosely based on the idea of a journey made by wanderers -- photographs capture the "beauty of solitude " Totally romantic and intimate and offers some examples of interesting lighting.
if you are interested in submitting. I am unsure if there is another volume in the works but either way it is a great collection of contemporary photographers!
