Time-lapse photography is an extremely effective way of presenting many geologic processes in the classroom. Developments in photographic equipment have made it possible to build a wide variety of equipment suitable for photographing and measuring geologic processes. New films, exposure controls and techniques promise better photography under diverse light conditions. Inexpensive apparatus can be designed for 8-mm automatic-exposure motion picture cameras, allowing students and teachers to make their own films. |
