Twilight and Moonlight at Waterfowl Lakes


Twilight at Waterfowl Lakes

Peaks of the Continental Divide reflect in the calm waters of Lower Waterfowl Lake.

These images provide a sense of what a beautiful night this was, last Monday on the Icefields Parkway in Banff.

The evening started with a super-clear twilight providing subtle shadings – from the last glow of sunset on the horizon, through the “twilight purple” above, to the deep blue of the darkening sky at top.

The purple hue comes from red sunlight still illuminating the upper atmosphere and blending with the blue sky from the usual scattering of short blue wavelengths.

The twilight scene is a high-dynamic range blend of several exposures processed with Photoshop’s HDR Pro as a 32-bit file in Adobe Camera Raw.

Star Trails over Waterfowl Lke v1

Taking different frames from the same set that I used to capture the Space Station I created this star trail scene, of the western stars setting over Mt. Cephren. Light from the one-day-past Full Moon illuminated the peaks that line the Continental Divide.

The star trail scene is a composite – of many images stacked to create the star trails, blended with a masked single image from the set to supply the landscape.

For the star trail stacking I used the excellent Advanced Stacker Plus actions from Star Circle Academy. To separate and mask out the sky from the landscape image I used Photoshop’s Quick Selection tool and its wonderful Refine Mask function.

Meteors and Space Stations over Mt. Cephren


Perseid Meteors over Mt. Cephren, Banff

A couple of Perseid meteors streak across the moonlit sky above Mt. Cephren in Banff National Park.

The night before the peak of the annual Perseid meteor shower was very clear for the first couple of hours. On Monday, August 11, I positioned myself at the shore of Lower Waterfowl Lake, at a roadside viewpoint on the Icefields Parkway in Banff National Park, Alberta.

I had two cameras going, one on a fixed tripod aimed west in hope of catching some meteors in a few frames. Two did, and the main image is a composite of those two frames, as the Perseids shoot over the pyramid peak of Mt. Cephren.

Later, the Space Station also flew over, accompanied by the European ATV cargo ship, captured here in a stack of 18 frames from the 555-frame time-lapse, showing their pass from west to east (bottom to top) of the composite image. The gaps are from when the shutter was closed for 1 second between the 15-second-long exposures with the 14mm ultra-wide lens.

In all, it was a warm and beautiful night, with the normally busy viewpoint all to myself all night, under the light of the nearly Full Moon.

The mountains by moonlight are truly magical.
