Sunrise Cloud Movements over Swiftcurrent Lake
Swiftcurrent Lake sunrise – Many Glacier, Montana.
Although we encountered wind gusting 25-40 mph and rains during our week long visiting Glacier National Park, this area is one of the most visually stunning locations that I have visited. The diversity of photographic opportunities were amazing: rugged mountains, towering peaks, dramatic clouds, turquoise lakes, raging waterfalls and cascades, exquisite flora and exotic fauna … I was in heaven. No wonder why this little corner of the world is known as “The Crown of the Continent“. Over the next few weeks, I will post a series of photos that I managed to capture during my time there.
This ninety seconds exposure was taken during my second sunrise photographing Swiftcurrent Lake in the Many Glacier area. The prominent peak on the right is Mt Grinnell and Mt Gould is under those fast moving clouds above the valley. Both mornings, the strong wind destroyed all the lake reflections:(
To maximize the wind effect, I stacked three GND filters (3 stops hard + 2 stops hard + 2 stops soft) to simulate solid ND filters to lengthen my exposure time. With the sunrise light changing rapidly every minute, I could not afford to experiment with too many of these long exposures and loose the exquisite sunrise light. In my next post, I will upload a much shorter exposure of the same location shot a few minutes later.
