Fun With Long Exposures
I had a couple opportunities during my recent trip to South Dakota to play around a bit with long exposure shots. In one case, I took some photos of Spearfish Falls with the apperture closed up all the way to f/22, plus I put on a polarizing filter to knock down the light another couple stops. As it was a pretty bright day, this still resulted in a shutter speed of 1/5 second — but I quite liked the results. I'm not really a fan of the super-slow photos of water that make it look like smoke or a milky mist: I want it to still be water.
In a much longer exposure of 30 seconds (at f/7.1), I captured the pre-dawn glow over the South Dakota badlands. A fair amount of tweaking was needed in Lightroom post-processing to bring out some detail in the ground, while still allowing Venus to shine in all her glory before the sun arrived.
