I love long exposures with moving lights. This is Amelia playing with a sparkler on the 4th. She had to be very still and just move the arm with the sparkler. The exposure lasted 21 seconds. Unfortunately my tripod isn't quite strong enough for my camera so she is not in focus. Plus I am still working on focusing issues myself.
This is for the fireworks challenge, not your typical fireworks, but some we enjoyed nonetheless.
