…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.
A clip divided by an exposure adjustment. The storm (right)moves into view as the daylight wanes, and the desert landscape with its red clay dims. In the distance three sharply pointed hills have eroded to the point where one tiny peak stands out on each mound, rock piles evenly spread around from crumbling. Time-lapse length (30 fps): 7 seconds and 21 frames.
In a sky that is perfectly clear of clouds, a small mountain valley with a single ridgeline sloping downwards gently further in the distance, which is lit by the sun slightly longer than the foreground. The sky quickly turns dark into a night sky, with lights from cars on a road passing, and planes flying. Over the course of the clip, several hours pass. Facing east at sunset and blue hour is less typical if this collection. Time-lapse length (30 fps): 16 seconds and 6 frames.
…over ocean time-lapse. Intricate and delicate, the underside of these clouds are illuminated minutes after the sun has set to the observer. How is this? The sun is below the horizon to the observer, but not to the sky above. At that moment, you would still see the sun if in an airplane at that height. You would be in its light, as are these clouds. Since these clouds are attached to a storm, their altitude could in fact be 30,000 ft or more. This would make sense, due to the low movement of the delicate parts of the cloud, which would have frozen droplets. Some lower clouds that make up lower thunderstorm bodies have a mix of frozen droplets, gaseous vapor, and liquid.
On a sliver of ocean with distant palm trees silhouetted far away, another younger storm is at the right of the lower frame portion. Blue sky persists in an area that homes other colorful clouds at higher altitudes of 45000 feet, or about 15000 m. The sun sets and the ‘mammatus’ clouds from the storm redden. Time-lapse length (30 fps): 25 seconds and 10 frames.
In the distance over Lake Tahoe, a fog bank is rolling. In the sky, clouds and crisscrossing contrails are illuminated around 40,000 ft in the morning sun, when colors change fastest (with the exception of dusk). The chardonnay yellows of the horizon and bluish-purple of the deep sky this dawn are on display. Time-lapse length (30 fps): 7 seconds and 11 frames.
Telephoto time-lapse with 1 second interval. The sun is observed at the ocean with a short exposure to capture the shape as it moves behind clouds. The sky is dark once the sun sets. The last few seconds remind one of a liquid droplet as the sun moves through more and more atmosphere on the far edges of visibility. Slivers of a long-distant cloud deep in the Pacific Ocean are completely silhouetted. Time-lapse length (30 fps): 22 seconds and 12 frames.
A desert scene in Canyonlands National Park, Needles district. Heavy clouds are overhead in this late-afternoon scene, and the shadows go over the foreground. In the background, around four tenths of the way up the frame, are the jagged needle-like formations this district is named after. The area around the needles is hike-able after a road that is relatively inaccessible. Time-lapse length (30 fps): 9 seconds and 3 frames.
A winter landscape at Grand Canyon facing north from South Rim, with light, fluffy clouds. Along the vista and foreground, the shadows of the clouds move steadily along the scene. The north side of the canyon has a blanket of snow on the rim, which is mostly under very low vapor cover. Time-lapse length (30 fps): 20 seconds and 11 frames.
