As much as necessary - as less as possible

I want to find out how a varying extent of content is changing the mediation of communication. Further questions, that may arise while working on this topic are:

• How much communication is necessary
• And necessary for whom? For the sender, or the recipient?
• What defines, what is exceeding the needful, what is unnecessary or what is missing to the needful?

These questions I do not only want to restrict to the written communication, but also extend to the visual communication. How is simplification or debauchery changing the visual appearance of content? From which point of the reduction or maximisation of content is distorting the content itself? On the example of translators - like for every other communication that is involving a third party - there is a risk, that para- and nonverbal signs may be terminated or corrupted. In which extent are there changes in the visual communication , that may have great impact on the reception? Whatever it may be: illustration, photography, moving image, interactive work and so on. These work results I want to visualise adequately. Afterwards I want to influence the reception by specifically changing the substance and therefore putting myself as a designer to the test.
