 Expo Aperture 2 depth of field guide : ExpoImaging, developer of camera accessories, including the ExpoDisc Digital White Balance Filter, today at Photokina announced the new ExpoAperture2 Depth-of-Field Guide, a pocket-sized circular calculator that enables photographers to determine the depth-of-field for a given focal length, aperture size, and sensor or film format. The ExpoAperture2 Depth-of-Field Guide has been improved to easily compensate for a camera's sensor or film size and to simplify its use over a wider range of focal lengths. The ExpoAperture2 Depth-of-Field Guide is printed front and back on three tough circular plastic discs that rotate against one another, functioning as a compact mechanical calculator.

 Depth of field guide
A photographer using the ExpoAperture2 Depth-of-Field Guide selects the camera's sensor or film size and desired focal length for a given shot. The Guide quickly and accurately provides the precise depth-of-field for a given aperture, or, alternatively, can determine the aperture necessary to achieve a desired depth-of-field. "The previous version of our Depth-of-Field Guide has been very well-received by even the most demanding and critical photographers," said Erik Sowder, ExpoImaging, Inc. President. "Now the new ExpoAperture2 Depth-of-Field Guide is even simpler to use in a wider variety of shooting situations. The latest version of the Guide is also better optimized for the wide range of sensor and film sizes available to today's photographers.
