  • 7 of 10 | Sierra Nevada Mountain range and midday clouds

    View with alternate video source

    Scene notes:

    Panning digitally upwards, while the mountains display four levels of cloud cover, with two on its peaks or flank. Altocumulus appears to follow the low clouds caught on the peaks, with the same amount of evaporation once over. The fourth layer is the high-altitude Cirrostratus, a layer of thicker Cirrus, not affected by the lower mountains.

    12 seconds and 20 frames.

  • Under Mount Whitney and others, clouds pass by in the sky, transforming and casting shadows on peaks

    Scene notes:

    Sharp peaks up close: young granite spires and glacial erosive features are featured in the lower ragged third of the frame, while low clouds transform just overhead left-right. On the sheer stone cliff faces, shadows are clearly moving past. Drops of solid rocks give way to trees where the less steep terrain allows any growth.

    12 seconds and 21 frames.

    … Airport, SFO at night under rainy clouds. The continuation of another clip (the camera has been moved). The airplane traffic (bottom right) zips by more frequently, landing at the airport. Other air traffic is seen. The city lights take up a sliver of the bottom of the frame. The

  • Mixed cloud sunset over rocky landscape and forest

    Scene notes:

    … in wilderness under clouds where the sun is seen. An exemplar of Altocumulus Castellanus near the center of the frame. Underlit with purple sunlight filtered from smoke, these clouds tower, owing that their names are derived from castle towers. At the end of playback, the sun can be seen brilliantly going down before disappearing into night. An airplane is seen zooming past in the sky, twice, in the upper-left frame. Upper-level Cirrocumulus clouds are gold in their altitude which gives them brilliant direct sunlight to the end.
    Time-lapse length (30 fps):
    12 seconds and 14 frames.

  • View-level clouds on mountain slopes just beyond a void of fog

    View with alternate video source

    Scene notes:

    At and below the point of view, flowing clouds between foreground stones and background mountain ridge that dips into the clouds at right. The clouds are blown away by wind, while the flowing stratus layer is seemingly kept out by the silhouetted ridge. A ‘sun dog’ is visible on the higher clouds (not to be confused with the lens flare).
    Time-lapse length (30 fps):
    13 seconds and 09 frames.
