Zoo_mosaic_21August2012

This is an 18-photo composite image of Zurich Zoo’s new elephant enclosure, still under construction. Aerial photographs were taken by a camera on board an autonomous Conservation Drone 2.0 that was flying at a speed of 10 m/s at 100 m above ground. The camera (Canon SX230HS) was CHDK-programmed to take photographs at 3 second intervals for 5 minutes (shutter speed 1/800, ISO 100, focal length 5.0 mm). **Upon request from Zurich Zoo, I have reduced the resolution of this image here to 1024 x 813 pixels, which is <10% of the original size and resolution.
