The new world: a camera that checks everyone is smiling

COLOGNE: The latest cameras at the Photokina trade expo last week in Germany have satellite-navigation features and switches that ensure subjects are smiling, an industry figure says.

The fair, held every two years in Cologne, is a major venue to launch new digital and film cameras, camera-phones, camcorders, lenses, flash systems, photo printers and software.

Organizers described the six-day event, which began on Sept 23, as the world's biggest camera show, with 1,500 exhibitors from 50 nations taking part.
