Take note that the focal length setting
(which measures the zoom setting for
the camera lens) in digital cameras are
different from conventional film
cameras. The reason is, since the CCD
(the device used to collect light) in the
digital camera is much smaller than a
film camera, all the lenses and their
focal lengths are smaller, too.
To make it easier for people to under-
stand the focal lengths of digital
cameras, manufacturers often quote
the camera lenses on a “35mm equiva-
lent” scale since this is more widely
understood by photographers. For any
digital camera, there is a certain
multiplication factor that converts to
this scale. (For example, 5.55 is the
conversion factor used by the Canon
S10 digital camera.)
For most digital camera models, Photo
Explorer can report the correct 35mm
equivalent zoom length values
automatically. It knows the correct
conversion factors since these values
are embedded in the program. As for
cameras that cannot be identified
automatically, Photo Explorer will show
an asterisk beside the zoom value, for
example, Zoom (Focal length): 41mm
(equiv.) *. In these cases, you will need
to enter the appropriate Conversion
factor in the Preferences dialog box -
Camera and Exif category. You must
also clear the Auto detect conversion
factor where possible option to disable
auto detection and use the value you
have entered.
