Shutter Speed, Part II

In my first shutter speed post I talked about how I prefer setting aperture as priority over shutter speed. Well while I was in the Smoky Mountains, I got to experiment more with shutter speed. We visited Laurel Falls, which was a 1.7 miles hike up a few hundred feet of altitude. There were other SLR-camera-photographers who carried tripods up the trail just to capture Laurel Falls. I was not prepared to carry my tripod up the hill, and also I forgot to pack it for the trip.

In order to get the cool smoky effect in the second picture, the shutter speed should set as slow (1/1.6 vs 1/60). Slow shutter speed blurs moving subjects while fast shutter speed "freezes" motion. Your camera should automatically auto adjust the appropriate aperture.

 However, slow shutter speed = shutter stays open longer = camera shake if you do not have a tripod. I had to find stable objects to set my camera on while taking slower shutter speed pictures. In the first set of pictures, I used the branches on the side and the second set I used the side mirror of our car.
