Each scene was constructed from portions of the Morewood parking lot on a sunny afternoon. Each image was taken with a Canon PowerShot SD300 and then resized and animated using ImageMagick. The relevant EXIF data reported by the camera was as follows:
Exposure Time: 1/160 sec. Aperture Value: 4.59 EV (f/4.9) Focal Length: 17.4 mm Shutter Speed: 7.31 EV (APEX: 12, 1/158 sec.)
As seen in the animated version of each scene, the hardest part of this trick is keeping the subject at relatively constant position and size while altering the field of view by changing the focal length and distance to the subject. This could be corrected later by digitally cropping and resizing each image.
