The sequencer enables the possibility of image series recording including automated re-parameterization of the camera based on different events and signals. Therefore the desired camera settings for each step are stored in so-called sequencer sets. Stringing together a number of these sequencer sets results in a sequence. The connection of sequences is done by using different paths. Alongside the camera features the path related features are also part of a sequencer set.


Sequencer sets

Sequencer sets combine camera features – comparable with a user set – and sequencer (set and path) related parameters.

Settings for several camera features such as

can be controlled by the sequencer and thus stored to a sequencer set as well as information for the set switch-over via four different paths.

Each path involves

As with user sets the camera’s current settings are overwritten once a sequencer set is loaded and the sequencer is activated.

Configuration

In order to avoid overwriting current camera settings while configuring a sequencer, the camera needs to be set to the sequencer configuration mode. Once the camera is set to the sequencer configuration mode, the individual sequencer sets can be selected via the SequencerSetSelector, configured and saved by executing SequencerSetSave. Starting the configured sequence requires to switch the sequencer configuration mode off and to enable the sequencer mode.
