Here are a few long exposure shots from a recent hike Allison and I went on through parts of Ohiopyle State Park in Pennsylvania. I would normally try a neutral density filter on the front of the lens to get the slow shutter speed needed to blur water movement, but in the case of these low-light, early evening shots, a low ISO and an aperture of around f8 were all that were needed. I am certainly glad (a least after the fact, not necessarily during) that I suffered through carrying the tripod- it really made all the difference. In the case of the blurred water, without that added stability, the shots themselves would be more or less impossible. Click an image to see a high resolution version on my flikr page.
