Intemediatlity: Coming between two things in time, place, or character; intermediate.
Oxford Dictionary
Different medias can come together and cross over to form new media, or to show new things. Technology is causing this to happen more and more often, with new inventions and applications we can bring together these forms more easily. A simple example may be how sound recording and photography can be combined to create television; however, with the internet there are more and more ways in which media can communicate with each other. It should also be noted that it is not a new idea, ancient greek and biblical artwork also uses multiple medias to tell storys, for example, a church could use a stained glass window to support a narrative.
For the purpose of my own work I feel it is important to recognise, and understand how the different media interact with each other, and the effect that this can have on the interpretation of my work. It can also be said that taking something from context and representing it a new way through a new medium, something called ‘transmediafication’ which is generally related to storytelling and fanfiction, but could also relate to the relationship between a photograph and a video, especially when the relationship is blurred.
In the past decades “intermediality” has proved to be one of the most productive terms in the domain of humanities. Although the ideas regarding media connections may be traced back to the poetics of the Romantics or even further back in time, it was the accelerated multiplication of media themselves becoming our daily experience in the second half of the twentieth century that propelled the term to a wide attention in a great number of fields (communication and cultural studies, philosophy, theories of literature and music, art history, cinema studies, etc.) where it generated an impressive number of analyses and theoretical discussions.
