‘Congestus’ clouds high above in the sky, towering as their namesake suggests, orderly in their
column of travel. They cover roughly two thirds to three quarters of the frame throughout. A five
second interval is used.
Time-lapse length (30 fps):
16 seconds and 11 frames.
The continuation of another clip. The Lenticular clouds are dominant in the sky. Many levels of
moisture enable these strange eddies of air currents to be cloaked in visible water. The landscape
(nearby mountains) is contributing to the formation of these less common clouds. High above the
desert landscape, a sliver of blue-sky remains in the beyond, and Cirrus clouds are on the top
layer.

16 seconds and 4 frames.
… and their small lights ascending before dawn. Multi-categorized clip. The moon sets behind Mt
Rainier. Looking closely afterward, a distant, single climbing party’s headlights are shown ascending
the rugged and impressive slope overnight. Morning comes, a blue hour, and far, far behind some
conifers, the snow of the mountain becomes pink momentarily against the rapidly changing sky, until
the sky is light blue, and it is day again.
Time-lapse length (30 fps):
38 seconds and 4 frames.
Pink light on the mid-level clouds. Strong radiant light passes through the atmosphere to create
underlighting for the slow clouds overhead with no horizon in frame.
Time-lapse length (30 fps):
12 seconds and 4 frames.
The sunset from Pike Creek Vista, Grand Canyon. The northwestward view shows the canyon stretching
vast distances under the sky, which comprises the top quarter of the frame. Mid-level clouds shape
the light above while the landscape shades itself, cliffs and precipices in the dark. The sun
disappears below the horizon in this darkening scene. Original footage from 2005.
Time-lapse length (30 fps):
12 seconds and 13 frames.
The tree line is a silhouette against the glowing sunset light, and is reflected perfectly in the
pond. The scene darkens as the clip progresses, and the sun has set.
Time-lapse length (30 fps):
13 seconds and 5 frames.
… in wilderness under clouds where the sun is seen. An exemplar of Altocumulus Castellanus near the
center of the frame. Underlit with purple sunlight filtered from smoke, these clouds tower, owing
that their names are derived from castle towers. At the end of playback, the sun can be seen
brilliantly going down before disappearing into night. An airplane is seen zooming past in the sky,
twice, in the upper-left frame. Upper-level Cirrocumulus clouds are gold in their altitude which
gives them brilliant direct sunlight to the end.
Time-lapse length (30 fps):
12 seconds and 14 frames.
This clip is illustrative of the under lighting that happens after the sun has set. From the altitude
of the clouds, the light is still briefly shining on them, and the clouds are turned pink and red
with oranges in between, and different levels of clouds are shown to move in differing directions
according to the winds at those altitudes.
Time-lapse length (30 fps):
4 seconds and 21 frames.
