5.3 Important instructions
• The WRC-1 controls
- the camera speed,
- the mirror shutter angle, and
- the iris of the lens.
All three parameters directly influence the exposure of
the film. In order to avoid unwanted results, and to
prevent the likelihood of incorrect use, all those
parameters controlled by the WRC-1 must be set and
controlled by the user. This also applies when one of
these parameters is not required for the currently
selected remote control: only when all three parameters
have been set (speed, mirror shutter angle and the
aperture) the film exposure is fully defined.
These values are defined separately for each mode,
i.e. the parameters can and must be individually set
for each mode.
Example: first of all a speed ramp is programmed and
shot. Then only the shutter angle is remotely controlled
for a transition from an outdoor take to an indoor
take. It would not be desirable to continue using those
settings that had been active at the end of the speed
ramp for the next take. Instead, the values set by the
user for the respective modes are active after switching
over to the other mode.
• When operating in WRC mode, the speed or mirror
shutter angle should not be set on the camera itself, as
these are repeatedly written over by the WRC-1. The
WRC-1 is an active unit and its settings have priority
over those of the camera. The camera retains the last
settings sent by the WRC-1 in its memory. This applies
when switching from WRC mode back to CAM mode,
as well as when disconnecting the WRC-1 from the
camera.
• All programmed end-stops and parameters set on the
WRC-1 are stored for as long as required, even when
the unit has been switched off. It is therefore possible
that end-stops for the handwheel had been pro-
grammed, which are not available when using this
WRC-1 with another camera model (e.g. high-speed
settings). The WRC-1 recognizes the connected
camera model, but does not independently change the
stored values. If these stored values should lie outside
of the range available for the connected camera
model, a warning is displayed.
