Vídeo de De derretimento de gelo e gelo no inverno de parabrisa de vídeo em HD

This is a timelapse video, with one continuous clip of 20 seconds running at 25 fps, featuring a frozen motor car on a cold morning in southern England. At first the frost and ice prevent the cloudy sky from reflecting in the car's metal frame. Then the ice and frost melts, and the reflected clouds start to race across the screen. Action is speeded up by 15x. This video is taken in natural light, and there is some flicker due to changing light conditions. Also a passing pedestrian and some motor cars. Full HD video from Canon EOS 7D. Camera is locked down. Frames processed to improve evenness of exposure. No sound track.
