The photo has been clicked by Jeffrey Martin in early October 2009 from the top of the Zizkov TV Tower in Prague, Czech Republic in collaboration with Prague 3 town hall.
A digital SLR camera and a 200 mm lens were used. Hundreds of shots were shot over a few hours; these shots were then stitched together on a computer over the following few weeks.
This is a super high resolution photo. Use your mouse to zoom in and see a startling level of detail.
This image is currently the largest spherical panoramic photo in the world. It is 192,000 pixels wide and 96,000 pixels tall. That’s 18.4 billion pixels, or 18.4 gigapixels!
