I was out last Friday and just happened to run into this protest. Students poured up from the Dupont Circle Metro then marched down Massachusetts Avenue to the Embassy of Sudan. There were around a hundred protesters, some of whom carried signs with the names of Sudanese villages that had been ethnically cleansed. I followed along on my bike and fortunately I had my camera with me.
I like this picture because it shows the motion of the cab and the number of people at the protest. I took it with my Canon Digital Rebel XT with a Canon 55-250 IS lens. I ran it through the “aged photo” filter in Adobe Lightroom to fade the colors a bit.
