Dave Pokorney shoots excellent camera stills of contra dancing and other subjects. He more recently has started documenting contra dancing on video.  He attends many dance events and currently has 108 short videos on youtube for open viewing. 

  Below are a few samples.  

Contra dancing in Coat and tails, Evening gowns, Cut-aways, Tee shirts, and Opera gloves?  you have to see it to believe it :)  ... Nice music too.  Shot at Putting on the Ritz Contra dance at the Decatur Rec Center
