    Scene notes: … of light rays through darker clouds slowly shifting. This is a slower clip with a very short interval and faster shutter speed. Crepuscular rays shine when there is a higher humidity in one area, but not necessarily very humid in the entire observable atmosphere around the observer. As the clouds move, the shadows defining the light rays move with them. The rays trace a path from the sun to the ground, and to the observer, the angles shift more the further the light path reaches from the sun.
    Time-lapse length (30 fps):
    9 seconds and 17 frames.

    Scene notes:

    …light rays through darker clouds slowly shifting. Because of a small patch of open sky, the sun breaks free into the valley below in between dense cloud cover of Cumulus type. Far in the distance is the barely visible horizon, which is cloaked in cloud shadow. This is the second clip in a scene of a few that were taken within the same 90 minutes.
    Time-lapse length (30 fps):
    8 seconds and 18 frames.

    Scene notes:

    …mid-level clouds at sunrise. UAS hovering at altitude at dawn. Altocumulus Castellanus are ideal clouds for creating light rays that persist. First, their presence in the sky indicates moisture at the medium levels. As droplets glow in the sunlight, areas of thicker cloud create the shade necessary for the ‘light ray’ to show with definition. Since Castellanus clouds have these small patches of thick density, stark sunbeams are cast toward the camera’s general point of view.
    Time-lapse length (30 fps):
    10:25.

  • Above Slash pines, crepuscular rays through clouds

    Scene notes:

    Crepuscular (afternoon) rays from being filtered by the clouds through a tropical treeline with what are called Slash pines. SKU/clip number: DAY335
    Time-lapse length (30 fps):
    7 seconds.

  • Looking up among ferns and a broken tree; light rays

    Scene notes:

    Scattered ferns in the frame, light rays above: there is a large and tall tree stump at left, and many fine light rays pass into the forest from fog ending just above. SKU/clip number: FRS056.
    Time-lapse length (30 fps): 17 seconds.

  • Fast low-level clouds near sunset creating crepuscular rays

    View with alternate video source

    Scene notes:

    A longer interval of around ten seconds is used. Clouds in the late afternoon at have enough space between them to allow sunlight through, and the humidity brings out vibrant light rays. The clouds blow quickly on the land, and as the second half of the clip goes, the light rays are observed to rapidly shift with the openings of the cloud positions. These crepuscular rays are not uncommon in partly cloudy, high humidity skies one to three hours before sunset. With days being far longer, the summer has more time and opportunity for these rays to reach through. But clouds are less common in Oregon during the summer, so often fall and spring are fair times as the day progresses, and some clouds are persisting. Far below in the frame of the clip, meadows are shadowed frequently among a forested, hilly landscape, with a lake in the far distance before the coast range of buttes and mountains. Length at 30 fps: 16:15
