Tips And Tricks - CULLMANN MRF 3500 Mode D'emploi

Taking photographs in automatic/manual
mode
You can use the Macro Ring Flash MRF 3500
to take photographs both in TTL mode and in
manual mode. This necessitates the use of the
CULLMANN D 3500 fl ash unit as a control unit.
The LED on the back of the D 3500 fl ash unit
shows you the mode which has been set.
A tapping of the „MODE" button results in a
switching from TTL to manual mode (M) with
various performances in the following order:
TTL > M 1/1 > M 1/4 > M 1/16
A repeated tapping of the button results in the
fl ash unit returning the TTL mode.
