Samenvatting
In 1963 Pictorial Crafts, Inc. began experiments and development of a vertical camera mount for use in a helicopter. Some projects require larger scale photography and mapping. Test photographs taken at 300 feet above ground proved to be free of blurring due to motion or vibration, and subsequent work performed for several governmental agencies at compilation scales of both 1 inch+ 10 feet and 1 inch - 20 feet was highly successful.
