The levels for experimental photography
An important challenge for experimental photography is to control rather
complicated sequences by the help of a controlling system. The task is to
control a large number of switching processes in order to achieve a desired
result.
While trying to put these processes together in your thoughts and program
these before starting the experiment, it is helpful to split the processes into
a number of small steps. It is easier to understand and program small steps.
When small steps are later linked to a “step chain”, complicated processes
can be assembled.
This concept of thinking and programming in small steps has been put into
practice in the jok

light barrier system. This gives the user an extremely
powerful tool which makes it possible to control simple as well as highly com-
plicated processes in an easy and comprehensible way.
The Steps
There are a total of 9 equivalent steps available, which can be used individu-
ally or, as described above, can be concatenated to a step chain. In the broad-
est sense, even a single step can also be considered as a step chain, consisting
of just one step. In the following, therefore, we will speak of step chains, even
if the chain consists of only one step.
A step chain can contain any number of steps and any number of step chains
can run at the same time. The number of these combinations is only limited
by the total number of 9 steps.
Important: The steps for controlling processes can and may be used
in parallel with the outputs described in the previous chapters.
However, because the outputs access the same switches as the steps,
undesired switching processes can occur if both work simultaneously.
Therefore, it is best to switch all triggers of the outputs that you do

The parameter sets of the steps, hereinafter referred to as X-parameters, are
each on one level, which are marked with the icons

A trigger can be assigned to each step. As soon as this is asserted, the "activ-
ity" of the step begins.
