Scene notes:

…clouds are illuminated from beyond the horizon, and below. Altocumulus Castellanus are mid-level clouds and have very intricate details, which are highlighted during sunset. A three second interval was used to show the progress of the colors shifting in the all-sky scene which is particularly majestic; these moderately dense clouds are named after the castle tops that sprout from streaking plumes.
Time-lapse length (30 fps):
10 seconds and 13 frames.

Fast low-level clouds near sunset creating crepuscular rays

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.

…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.

Scene notes:

…under cirrus, cirro-cumulus after sunset, flowing high elevation clouds. At these elevations, clouds are formed with tiny frozen crystals. As the movement is demonstrated in the one most aesthetically pleasing cloud, there is a flowing that is unique to the temperature of the cloud, highlighted with beautiful pinks. Sunsets like these where the sky illuminates clouds ‘from below’ prove the Earth is a sphere and not flat. The sunlight would be abruptly blocked by a sudden end to the Earth’s crust if it ended somewhere in the ocean. Instead, the light goes through more and more atmosphere the higher it reaches into the sky, until the sun sets from the cloud’s perspective as well.

Scene notes:

… 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.

Scene notes:

A nearly five second clip of a sun setting far in the distant hills behind a city’s skyline. A highway is seen with traffic moving on it far into the shaded urban landscape below, complete with the UC Davis Health Center and hospital, traffic light quickly alternating traffic flow. The UAS captures two thirds of the sky in the upper frame. Behind clouds, the shadows demonstrate a takeover of the sky, where the sunlight once glowed on the lower fringes of these mid-level clouds.
