A 50mm lens at open aperture (f1.4). Far above a mountain peak, a mid-level cloud layer gradually works its way into the frame, silhouetted in the dark night sky. Coma (comatic aberration) is present at moderate levels.
Time-lapse length (30 fps):
7 seconds and 13 frames.
…Airport, SFO at night under rainy clouds. Continental traveling airplanes are seen landing over the bay diagonally across the frame. The bright lights of a few are visible among the other city lights, taxiing for takeoff or to their gates. In the bottom quarter of the frame the water moves, and reflects the light of the clouds, illuminated in the city’s lighting. The lower stratus clouds bring rain on the city across the water.
Time-lapse length (30 fps):
9 seconds and 18 frames.
Mid-level clouds float over the point of view in the night, a starry sky above the mountains, which strongly rise on the left. A glacier of packed, icy snow resides in a distant slope near-center. The altostratus varies in its coverage of the sky; it ebbs and flows.
Time-lapse length (30 fps):
9 seconds and 28 frames.
As the moon rises and the frame zooms in digitally, the mountains increase in natural light, stars overhead in a cloudless sky. The scene displays low to medium coma. The mountains are half-snow-covered, the other half is too steep, rock faces and cliffs that plunge. Flutings comprise the cirques of accumulated snow.
Time-lapse length (30 fps):
12 seconds and 28 frames.
…or a sunset on snowy bright mountains. The moon rising sends enough alpenglow to the mountainsides to brighten them like a sunrise. The stars overhead in the top half of the frame wheel around as the Earth spins at night.
Time-lapse length (30 fps):
16 seconds and 25 frames.
The mountain rises into the night sky, cloudless, and starry. A low to medium amount of coma is evident.
Time-lapse length (30 fps):
15 seconds and 29 frames.
Low mist pouring over darkened mountains at night. Stars move overhead in very long exposure and large aperture.
After blue hour, mid-level clouds, patchy and fleeting, move in steadily in the moonlight, shadows dimly moving on rock faces near the bottom-right of the frame at points. Mt Whitney (center) and neighbors are silhouetted in the night, with nearer mountains that are shorter but much closer on the left and right flanks.
Time-lapse length (30 fps):
20 seconds and one frame.
