// Script written in ImageJ Macro Language (IJM)

// Description:// This macro makes a digital 3D object out of an image sequence// It asks for a directory path, then impots all images, converts them to 8-bit, substracts background, applies a smooth filter and runs the 3D viewer with some predefined parameters

// To run the macro: open ImageJ, from the top menu Plugin, select Macros then Run… choose the file from your local disk.

// For information on how to use imageJ, see// http://rsbweb.nih.gov/ij/

adaptations

to target to source

A double act of communication

Translator

Transforms the artefact into an object of his/her own experience

Can be a member of the same culture as the sender or as the receiver

[ Schema adapted from: Sonesson, 2011 ]

Translation != encoding, transference, transportation, transposition

Translation == communication

• Receiver and sender are active

• Different cultures of sender and receiver

• They have to retrieve resources from of each other

Communication

• Presenting an artefact to another subject

• Assigning him/her the task of transforming it by means of

concretization into a percept

• Creating the artifact is a social act: it is determined by a set of

norms (aesthetic, social political, psychological or of any kind)

Intra-linguistic: changing one word/phrase of the same language for another

Inter-linguistic: from one verbal language to another

Intra-pictorial: exchanging one drawing for another

Inter-pictorial: substituting a photograph for a drawing

Intra-interfacial: substituting a “bouton” for another of a different kind

Inter-interfacial: exchanging a “bouton” for a slider

Inter-semiotic translation: transference of the content from one kind of

semiotic medium to another (e.g. novel ➜ film)

We are dealing with inter-semiotic translation

It is a transposition of elements from the whole culture

Sometimes happen implicit intersemiosis

Challenge of deformations

• Receiving culture has to create its own version of foreign elements

• Are there domains more oriented towards Receiver than Sender?
