Operating modes
Keep-active mode
All cameras have a certain lag time, that varies depending
on the camera model.
This lag time can be annoying because the picture is cap-
tured later by this time, measured from the moment of in-
terruption of the light barrier. Depending on the camera
the lag time can be from 10 to 300 ms.
In addition the lag time varies from one release to the
next. This variation also depends on the camera model.
Some of them have a variation of a few milliseconds, oth-
ers varies some tenths of milliseconds.
Using the keep-active mode of the light barrier Jokie² the
lag time can be reduced significantly. At the same time the
variation is also reduced significantly.
To activate the keep-active mode switch on the switches 3
and 4, see Image 13.
This mode behaves as if the the release button is
pressed halfway all the time. Therefore the review of
pictures is not possible, as well as life view modes, if
existing.
To review the pictures switch off the keep-active
mode or disconnect the camera from the light barrier.
Wake-Up
Most cameras and speedlights activate the power saving
mode after a certain period of time. In the case of some
devices this function cannot be turned off using the cam-
era settings.
To keep these devices “awake“, the light barrier activates
the camera every 10 minutes similar to pressing the shut-
ter button halfway down.
The wake-up function is always active, it can not be
turned on or off.
