ExpoAperture2 Depth of Field Guide
Bruksanvisning i pdf format
The ExpoAperture2 Depth of Field Guide is a versatile and unique tool which instantly shows you the relationships between focal length, focus distance, aperture and resulting depth-of-field. The ExpoAperture2 Guide empowers photographers to take control over depth-of-field and to apply selective focus easily and effectively in their photography.
A photographer using the ExpoAperture2 Depth-of-Field Guide simply selects the camera’s sensor or film size and desired focal length for a given shot. The Guide quickly provides the resulting depth-of-field for a given aperture, or, alternatively, determines the aperture necessary to achieve a desired depth-of-field. The Guide also easily calculates hyperfocal distances. The Guide is designed so that beginning and experienced photographers alike can quickly compare the relative variables (aperture, lens focal length and subject distance) to determine which combination works best for their chosen shot. In this way, the Guide enables photographers to exercise better creative control over their cameras and images.
As a tool for everyday use, the ExpoAperture2 Depth-of-Field Guide can easily fit into a shirt pocket or camera bag for convenient access when needed. The Depth-of-Field Guide is printed front and back on three durable, circular plastic discs that rotate against one another, effectively functioning as a compact mechanical calculator.
