Abstract
A photographing apparatus includes a photographing plan memory for setting photographing conditions based on a predetermined photographing plan, a vibration sensor for detecting vibration caused by an explosion of a balloon serving as a photographic subject, and a trigger generating circuit for taking in the timing of detection by the vibration sensor as a trigger. The above photographing plan is prepared beforehand for changing from low-speed photography to high-speed photography in response to the trigger, and changing from high-speed photography to low-speed photography after acquiring “40 frames”. With this plan, the low-speed photography is adopted before and after the balloon explosion, an amount of photographic data tends to be small. Photographs may be taken out within limited photographic data, even with a limited memory capacity. At a moment of balloon explosion, rapid variations due to the explosion may be photographed by high-speed photography with high accuracy.
