    Scene notes:

    … Backlit by the sun making stark contrast, undulating. These low-level clouds move along a wind left-to-right, transforming as they go. Stark backlighting is necessary when capturing crepuscular rays and shadows to preserve highlights. Two or three separate bands of cloud are evident in the lower half of the frame, the largest of which show signs of nearing future precipitation, with the upper half containing smaller patches of varying density overhead. Length at 30 fps: Seven seconds and nine frames.

    Scene notes:

    High clouds fly silently overhead this unnamed arch complex in the park of the same name, Arches National Parks. At over 80 feet diameter, the sandstone is a testament to erosion.

    Scene notes:

    …rocky, snowy winter peaks. Symmetrical slopes dominate the frame, with rocks and small boulders among evergreens that lead up to near the very tips of these mountain tops. With light, low rolling clouds pouring over and piling on these steep slopes, jagged, snowy peaks poke out like jigsaw teeth.

    Scene notes:

    Low-level, fluffy clouds, and high-level Cirrus: the two classic cloud types are seen spreading out and floating gently over the expansive sky with the Three Sisters (third peak is out of frame) at the bottom-left.

  • 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.
