Europe’s largest annual meeting of hot air balloons, attracting over 130 Hot Air Balloons from across the globe. A historic bridge was opened in 1864 and stretches over river Avon in Bristol. It was designed by famous engineer Isambard Kingdom Brunel. A building with the tower is Clifton Observatory which offers a fantastic camera obscura view of the bridge. These stereoscopic images were taken with IPD of 20cm, exaggerating 3D effect like seen by a "Giant".
