The Milky Way over the sandstone hoodoos of Writing-on-Stone Provincial Park in southern Alberta. This is a comppsite of a single 30-second untracked exposure for the sky with the Canon 6D at ISO 4000, and 24mm lens at f/2, as the final frame of a 300-frame time-lapse, with a 6.5-minute exposure for the ground, taken at the end of the time-lapse with the lens stopped down to f/4 and the Canon at ISO 1600 for lower noise and better depth of field. This final frame of the star trail time-lapse at Writing-on-Stone is made to crossfade to from the movie. Two versions of the ground are in the layered PSD file for demo purposes — 1) from a stack of the last 10 frames and 2) from a single 6.5 minute exposure with an LENR dark frame but the camera shifted a little so that image had to be manually aligned.
The Big Dipper, at left, and Little Dipper with Polaris, centre, over the Hoodoos on Highway 10 along the Red Deer River near Drumheller, Alberta, July 24, 2016. A faint purple aurora lights the sky at upper left, while clouds lit by farm and urban lights provide the unfortunate but in this case complementary coloured yellow sky glow. A nearby farm light illuminates the foreground hoodoo. The waning Moon was just coming up and beginning to light the sky blue as well. This is a 2-panel panorama, vertically, to take in more of the sky and ground than possible with a single image, even with the 20mm lens used here. The sky is a 30-second exposure at f/2.2 while the ground is a stack of 3 x 2-minute exposures at f/4.5 for more depth of field. All with the Nikon D750 at ISO 3200. No tracking here.
Cloud formations called mammatiform clouds caused by downdrafts in a thunderstorm being lit by the setting Sun making the protruding clouds all the more obvious. Captured in grab shots from home with a handheld camera quickly taking several segments for a panorama. Stitched with Adobe Camera Raw. This set was taken a couple of minutes later after v1, when the intensity of the sunlight was diminishing but the colours were still fine and rather pastel.
