Control Your Focus With The ExpoAperture Depth-of-Field Guide

ExpoImaging, Inc., developer of innovative camera accessories, including the ExpoDisc Digital White Balance Filter has announced the availability of the ExpoAperture Depth-of-Field Guide, a pocket-sized circular calculator that gives photographers creative control over their depth-of-field. The ExpoAperture2 Depth-of-Field Guide is available for purchase at select photography dealers nationwide or online at www.expoimaging.net.

The ExpoAperture Depth-of-Field Guide is a simple and convenient reference tool designed to enable the photographer to quickly evaluate the relative depth-of-field (what will be in focus) given a chosen aperture and lens focal length. The guide will just as easily provide the best aperture to achieve a desired depth-of-field.


The ExpoAperture 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. The Guide's ease of use makes this a perfect tool for new photographers, helping them to determine the best aperture to achieve a desired depth-of-field.

The ExpoAperture Depth-of-Field Guide is intended for the educational, hobbyist and professional markets. The ExpoAperture Depth-of-Field Guide is compatible with all film and digital SLR cameras and includes a Quick Start guide, instructional CD, Camera Sensor Reference Chart, and a handy storage pouch.
