This is the set-up we used, documented. Sam Dodge and I put this together at BarCampMilwaukee5 to take people’s portraits… for free! And that’s free as in beer, free as in speech, and free as in freedom! We let the subject of the photo use the image for ANYTHING they want, and in return, we get to publish it under a Creative Commons license, which also creates this record of people who came to BarCamp. It’s the second time we’ve done this, and this time, we actually planned ahead… well, a little bit.
