The eastern part of Glacier National Park is the windy side. It’s also the quiet side in terms of people. The lakes are the main attractions. Swiftcurrent Lake is one of the park’s jewels! In all the years I’ve been photographing these lakes, I’ve only seen a smooth, glass-like surface once! And it was obvious as we stood in the dark an hour before sunrise that this was not going to be the second time. In order to ‘create’ a smoother surface, I used my Vari-N-Trio. With the benefit of the that filter’s built-in warming polarizer and color intensifier all that was needed was to first set a shutter speed and aperture combination that would give a long exposure to blur the water and achieve enough depth of field to keep the foreground rock in sharp focus as well. The last step was to use a 2-stop soft-step ND Grad to hold back the exposure of the moon near the horizon. The exposure was 30 seconds at f/16 at 100 ISO.
