Only light reflected by the subject is measured. When
this metering method is used, results are always
dependent on reflection from the subject! This means,
for example, that intrinsically bright subjects will be
reproduced darker, and not as precisely exposed as with
the incident light method.
When employing this metering method, the use of a
suitable grey card (18% coefficient of diffuse reflection)
will help to deliver consistent results.

Measured f-stop increments (1 EV, 1/2 EV, 1/3 EV) can be adapted as required by the user in
Menu
– User (Cam 1, Cam 2, Cam 3, Cine) - EV Steps (see page 25).

The DIGISKY works with f-stop increments of 1/10 each. Measured correction values for the
display value are specified in 1/10 f-stops depending upon your EV Steps setting.
