One of the best things about Grand Teton National Park are the many turnouts and overlooks that have been built along the park's two main roads, US Route 89 and Teton Park Road. These stops on the road provide many beautiful views of the massive Teton Range, which are part of the larger Rocky Mountain Range. I have a particular affinity for the Blacktail Ponds Overlook.
Best shot at sunrise, you really need to get there early enough to get the morning light as it begins to light up the peaks and work its way down the mountains. One of the challenges when shooting here at this time of day is the high dynamic range of the scene that is often difficult for cameras to capture. Trying to blend the very bright mountains and the very dark foreground takes a bit of thought and practice. There is a fine line in balancing the image, by bringing out details in the shadows while reducing the highlights to bring out the mountains.
