Animated photo of the cloud spill
consists of 10 distinct images, taken one every 10 sec and played back
with a 0.2 sec delay. This speeds up the motion by a factor 50
times. In other words the 100 sec time lapse of the original
sequence is played in 2 sec. The loop is repeated.
Notice how the fog evaporates as it descends down the slope on the near
side. This is due to the heating of the air containing the fog as
it is warmed by compression at the lower altitudes.
Technical details: The digital camera was set to a 3x zoom
and used a 1600x1200 resolution. The fog was estimated to be 4
miles distant from the photographer. The image is highly cropped
to "zoom" into the feature. The animation frames are also highly
reduced in size to preserve data size. The 10 individual frames
were combined to form an animated image using tools in StarOffice
