Drum maker Ronn Dunnett (Dunnett Classic Drums, George Way Drum Company, www.drumsmith.com) is also an accomplished photographer. Check out his pictorials of many drum expos and shows (NAMM, Musik Messe, Chicago Drum Show, Hollywood Drum Show, and many others) here. 

The one catch is you have to register. But I highly recommend becoming a part of the site. Good people and good discussions!
