Rasgueado is the Spanish term for a downward brush with the fingers to produce a sound much favoured by Flamenco guitarists. The hand and guitar in question both belong to Ben Kearsley (www.benkearsley.com is his website which I designed and produced); the attempt to capture the fast movement without stopping the action completely (and so continue to suggest the explosive action that is required), is down to me and a Canon 50D with continuous studio lighting. He's on at this year's Edinburgh Festival which you can't miss - even if you live in America, Holland, Russia......just come along and you'll be made welcome!
