  • Light upper-level clouds float over Mt Whitney in a natural auditorium

    View with alternate video source

    Scene notes:

    Cirrus clouds float undisturbed over aretḗ (French for this terrain feature which has no English counterpart) mountain peaks (center). The southern facing cliffs (right) are largely free of snow, while others still retain a great deal of it. Cornices shed fresh snow in high wind (middle peaks). The sky comprises a third of the frame, with the sun visible late clip.
    Time-lapse length (30 fps):
    7 seconds and 16 frames.

  • Optical effect around-mid day sun looking upwards at Cirrus

    Scene notes:

    The partial halo from stratocirrus clouds. Other clouds in the frame do not contribute to the halo itself.
    Time-lapse length (30 fps):
    8 seconds and 2 frames.

  • A viewpoint from south rim of Grand Canyon

    Scene notes:

    In the mid-morning with clouds above and cliffs all forward. The continuation of a Night clip. The exposure has been adjusted for the daytime. The high Cirrus clouds are tending to clear, as well as the smoke in the window of the canyon beyond where impassable red rock cliffs, scree and degraded side slopes, and colluvium boulder fields dominate the land below.
    Time-lapse length (30 fps):
    9 seconds and 11 frames.

    …a medium for optical halo illusion around the high sun. The continuation of another clip.
    Time-lapse length (30 fps):
    11 seconds and 13 frames.

  • Death Valley landscape with sand dunes with shadows creeping up mountains

    View with alternate video source

    Scene notes:

    A slow desert scene featuring a few high clouds and arid sand dunes below. The sand dunes comprise ABOUT of half the frame. The distant mountain ridges occupy one fifth. The peaks of Black, Funeral, and Grapevine mountains are off to the east in the distance. The shadows on the ground in particular become longer.
    Time-lapse length (30 fps):
    10 seconds and 21 frames.

  • Sierra Nevada Mountain range and midday clouds panning

    View with alternate video source

    Scene notes:

    Wide-angle view of Sierra Nevada and the deep blue-sky above, panning leftward over the shrublands and dynamically shadowed landscape from clouds passing by at low, medium, and high altitude.
    Time-lapse length (30 fps):
    11 seconds and 26 frames.

  • Sunrise over Grand Canyon with vibrant mixed clouds changing at dawn

    View with alternate video source

    Scene notes:

    The sunrise is displayed on Grand Canyon, light slowly brightening. The clouds above in the shifting sunlight transform wildly in the new light, and then gradually lose previous semblance of color. Instead of being lit from below, the clouds above are lit from above shortly after dawn. The desert canyon vista that stretches many miles is eventually illuminated like any other day.
    Time-lapse length (30 fps):
    50 seconds and 4 frames.

  • Clouds with Sierra Nevada range appearing from haze on meadows in the day

    View with alternate video source

    Scene notes:

    Shadows play across the desert and mountain landscape as the camera pans rightwards. Shadows from these lower clouds that have moved overhead shift the light on the land. High clouds move onward while the stratus layer hugging the mountainous peaks transform in time and the higher wind. The higher north faces of these cliffsides are steeped in snow.
    Time-lapse length (30 fps):
    12 seconds and 8 frames.
