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.
