This diagram was used as the base model for the screen component of Fashion City, an walking installation that explored the Fashionable Nature of Melbourne. The basic structure represents the three levels of an image sequencer, and the individual sequencers within each level.
The three layers each had there own set of properties that directed the content that was used within and how that content was selected for each iteration or cycle.
It was important to explore and gain feedback on how these three layers would be used, the principle feedback that I requested was by Neal Haslem and it was through these discussions that the final format and parameters where set. It should be noted at this point that the parameters where not about formal conventions more about the essence and quality of each layer.
The final properties where:
Level 1 - base layer
This layer would be made up of curated image sets, and in the xml documentation of a sequencer this layer could be set by the sequencer editor.
Level 2 - middle layer
This layer is made up from one of the tag sets that anybody could submit an image to. The final number of sets was ... . This layer would always be chosen by the system, and could not be set by the sequence editor. In submitting images the person who submitted the image also choose the tag to which it belonged.
Level 3 - top layer
This layer mimicked the properties of the base layer. Though the image sets for each layer where kept apart.
The essence of each layer was set in part by their relation to one another, and by describing the system in terms of musical sequencing ideas, each layer took on the musical properties of Base, Mid and High notes [ elaborate on this ] .
In describing the properties of the layers I have introduced another part of the system, this being the use of composed squences. These patterns allowed editors/composers to set a patterns tempo, to describe the content for the top and bottom layers – including random [ elaborate on this ]. Within the sequence an editor could also set the number of measures that a sequence would last for and the beats to change an image on. For each image the editor could also set the duration for the images fade in and fade out and the length that the image stayed on screen.
