CAMERAS BAFFLED
Humming birds' wings have baffled Britain's fastest cinema camera. For weeks the Air Ministry has been endeavouring to photograph humming birds in action as an aid in perfecting the helicopter, but the .ttempts wore unsuccessful. Humming birds hover in front of flowers, sipping the nectar while stationary in tho air, and this is the secret which the Government officials have been trying to record on tho film. One film was taken at the rate of 300 exposures per second, but tho birds' wings were entirely too fast. Only blurs showed where the scientists had hoped to see wing movements. A faster camera apparatus, to take 1000 pictures a second —equalling an exposure of l-2000th of a second—is to bo brought into use if possible.
