70 gigapixel picture
In 2010 360world created the world's largest gigapixel panorama.
This panorama of Budapest was created using a setup of two 25-megapixel Sony A900 cameras fitted with 400mm Minolta lenses and 1.4X teleconverters. Four days of shooting resulted in 20,000 images, and an additional two days of post-processing produced a single 200 GB file. If printed, the size of the photo would be about two apartment blocks long and ten stories tall.
