Setup and alignment of the light barrier
In nature photography, light barriers are usually set up in
places where one knows exactly where and in which direc-
tion the subjects (animals) move. Examples are feeding
places, nests, dens, runways etc. On the other hand, in ex-
perimental photography, the light beam crosses the flight
path of the desired object.
Setup
Usually light barrier and reflector are mounted on tripods.
The more solid the setup is, the less wrong releases will
occur.
Install the reflector in a place outside of the image section
and position it so that it faces the light barrier. A precise
alignment is only necessary if you aim to work with the
maximum reach.
After that the light barrier should be mounted and the
power supply as well as the camera connection cable be
connected.
Alignment of the light barrier
At first point with the beam above the reflector and move
the light beam – in a meandering pattern – into the direc-
tion of the reflector. The distance
a
of the horizontal routes
should be smaller than the diameter
d
of the reflector (im-
age 14), otherwise you might move the light beam around
the reflector and miss it (image 15).
Meanwhile watch the LED of the light barrier. Without re-
flection it is turned on. As soon as the beam hits the re-
flector, the LED will go out.
Meanwhile watch the LED of the light barrier. Without re-
flection it ON. As soon as the beam hits the reflector, the
LED will be OFF.
