…Clouds still lit from below. Hovering above the city (bottom-right) Sacramento. Mid-level clouds
with light from below the horizon’s sunlight.
Time-lapse length (30 fps):
10 seconds.
…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):

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.

…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.

… 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.
