ExpoAperture2 Depth of Field Guide from ExpoImaging



ExpoImaging has released its new ExpoAperture2 Depth-of-Field Guide which now contains two calculator discs to cover focal lengths from standard to telephoto.

ExpoAperture2 includes a Standard Disc covering the focal lengths from 15-135mm and a Tele Disc for focal lengths from 70-600mm in 35mm film equivalent.

This circular analog DOF calculator instantly shows the relationships between focal length, focus distance, aperture and resulting depth-of-field. The ExpoAperture2 Guide enables photographers to take control over depth-of-field and to apply selective focus 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 two-disc ExpoAperture2 is available online for about $40 from ExpoImaging or from any of its dealers worldwide. In the UK, Flaghead is selling it for £25.85 including VAT.
