Here's the last of my images from last weekend's camping trip - this time playing around with campfire sparks again. I like how the spark trails map the hot air currents above the fire. Hope you like them too...
Malcolm, these were 1-2 second exposures using my K100D and 18-50mm lens at f/5.6 and 800 iso. I was banging a stick against the logs in the fire to generate sparks during the exposures (much to my 8 year old son's delight!)
