and the number of copies you want to print can be specified and stored onto the card where the
image has been stored. This will allow for easy printing using DPOF compatible Print Shop

EV (Exposure Value)
From an exposure value of zero EV defined by the combination of an aperture value of f1 and
the shutter speed of one second. Each time you halve the amount of light collected by the
sensor by halving the aperture or by doubling shutter speed, the EV will increase by 1. The EV
can also be derived with respect to brightness and ISO sensitivity.
