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.

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.

Drone hovering at sunset into dusk, Sacramento skyline

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.

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.

Mammatus clouds above hills darkening away at dusk in the sky

Scene notes:

The scientific adage of ‘what goes up, must come down’ rings true in this scene where, at right, lower-level clouds rise in convection. Over this ridgeline, there are pockets of air that fall through the cloud as cold patches, creating these distinctive looking clouds. While the dire, dark gray, bizarre looking ‘mammatus’ are this size only 30-40000 ft and attached to monstrous storms, these are clearly harmless clouds.
Time-lapse length (30 fps):
7 seconds and 15 frames.

Dusk-to-night over rocky landscape into stars and blueish darkness overhead

Scene notes:

Sunset with pink clouds rapidly changes to blue hour and nighttime, a huge boulder field is silhouetted on the sky, which has high clouds that evaporate in the night quickly.
Time-lapse length (30 fps):
20 seconds and 24 frames.
