    … after-sunset lighting on high clouds. This mid-level cloud layer dominating the sky with small patches has clouds resembling Lenticulars. If the layer of cloud were thicker in its altitude, the lens shapes would be more apparent. A wispy row of Cirrus is absorbed in the cooling sky, pink colors fading with them, and below on the surface, a highway curves by a skyline of Sacramento, and extend west with lights of individual cars passing by in hyper speed; 90 x 60 mph = 12900mph apparent ‘playback’ speed. 90 represents the speed of the time-lapse over ‘real’ time. The Time-lapse length of the clip at 30 fps is eight seconds and ten 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.

    … and blue sky, facing east at sunset to Mt Shasta. Here a low-level cloud strand streak off the summit, and mid-level altostratus clouds catch the colorful sunset light. The mountain (lower left) is snow-covered and stands beyond a foothill of Manzanita bushes and shrubs, as well as distant evergreen Conifers.
    Time-lapse length (30 fps):
    43 seconds and 2 frames.

    Scene notes:

    Cumulus picking up more reddened light due to the angle of the sun. The light is post-sunset. Clouds at low and medium levels move in the same wind overhead and past. A three second interval is used.
    Time-lapse length (30 fps):
    33 seconds and 21 frames.

    … higher clouds at sunset. Post-sunset, underneath the clouds, the light is caught. Moving to the right, a gradual clearing of glowing mid-level clouds give way to Cirrus clouds still bright in the sunset light in the upper-right half of the frame.
    Time-lapse length (30 fps):
    19 seconds and 11 frames.

  • Different cloud levels and densities in a blue-sky on the wind transforming on time

    Scene notes:

    A clip of Cumulus clouds (the lowest), Altocumulus clouds (the middle height level), and Cirrus of various kinds, such as Cirrocumulus. An example of how clouds also can move in different directions, the cerulean blue-sky has high air quality as the smaller clouds meander around.
    Time-lapse length (30 fps):
    15 seconds.

  • Mid and upper-level clouds shine and fade at sunset

    Scene notes:

    Floating past, a rapidly deteriorating Cumulus congestus (towering cloud) is absorbed by the slightly dryer air it moves into. Above, many layers of thinner clouds and medium-thick clouds also transform in the rapidly setting sun, which is out of frame at right the sky darkens, but brighter portions of clips can always be trimmed for use.
    Time-lapse length (30 fps):
    11 seconds.
