Some weeks ago, I was discussing the term sampling; it was of course in relation to electronic music. I’m not into sound or music and my take on the conversation was that sampling is part of visual media too. My argument is that taken as a three-dimensional object, the moving image needs to be sampled to be experienced. Two axes of the object are the spatial coordinates x and y, and the third axis is time. Thus, film samples the moving image in the time-axis at 24 images per second; analogue video and digital video add to the sampling the spatial coordinates. However, the reorganization of a particular beat or sequence of beats of music to produce a new composition, rhythm, or even musical genre has no counterpart in the moving image media. One could argue that the narration and even framing or images of a particular film of video are remixed producing thus new productions. This is done all the time in cinema and more conspicuously in T.V. spots. This however is different from sampling and follows the logic of remix and media quotation (remediation?). When there is a case of visual sampling it is the sound that creates the rhythm, not the moving image.

Visual sampling? Close your eyes and see if you miss the images.

Surveillance made simple

A didactic explanation of how the age of ubiquitous surveillance functions. Nothing that wasn’t already in the program of the computer, though.

(auto-)retrato at Festival Internacional de la Imagen

One variation of my (self-)portrait, (auto-)retrato: 100 fragmentos, variaciones 1 y 2, has been selected for presentation in the Media Art show at the coming XII Festival Internacional de la Imagen in Manizales, Colombia.

Work’s statement in Spanish:

La interrupción de la máquina facial solo es posible a través de la fragmentación interna del tiempo y el espacio del cuadro.

Este (auto-)retrato es una aglomeración, en un mismo cuadro, de imágenes grabadas con un celular en diferentes momentos y lugares. El objetivo es diluir mi propia imagen a través su fragmentación. Variación 1 y 2 se componen de 100 fragmentos de grabaciones de vídeo. Cada vídeo ha sido grabado por una persona diferente en momentos y lugares diferentes usando una cámara de celular. En cada variación los 100 vídeos son reproducidos simultáneamente y son ubicados en el cuadro de forma aleatoria hasta llenarlo completamente. El resultado es un vídeo compuesto de una serie consecutiva de tiras verticales de vídeo una al lado de la otra. En estas dos variaciones se juntan 100 “”yos” separados en el tiempo y el espacio.”

Coincidence or Plagiarim?

Tags: , , , | Categories: art, digital media

Ideas improve. The meaning of words participates in the improvement. Plagiarism is necessary. Progress implies it. It embraces an author’s phrase, makes use of his expressions, erases a false idea, and replaces it with the right idea.

f(you * γ): reflexions after Lübeck

Two weeks ago I presented my (self-)portrait in the general meeting of DAAD scholarship holders in Lübeck. After the presentation several issues generated a vividly discussion. I’ve grouped those issues under two fragmentations: of the frame and of the author. The first, evident in the visual outcome, is the fragmentation of the space within the frame. The second refers to the crowd-sourcing strategy I use for the production of the portrait.

Video is a medium primarily concerned with time. This medium fixates time into a series of independent recordings that we watch in rectangular frames. Almost always the space of the frame is filled with one image that represents one time and one space. Although video fragments time, the visual frame keeps in each recording a unified time and space.  The camera can only record a sequential flow of time; it cannot record several, non-sequential moments of time simultaneously. The simultaneous assemblage of different times within the frame occurs always in the montage. In my work this is not different. I record each time one minute of video of myself but in the final composition, a real-time montage, all these recordings are agglomerated and played simultaneously within the same frame. Each recording is cropped to a few pixels width and placed next to another recording. This procedure produces a moving image that is composed by several other moving images. The frame is thus fragmented into several columns and each of these columns is filled with a different video. The fragmentation of time that video generates is carried to the very frame. The manipulation I propose has a spatial character. Such a procedure, I would claim, it is only possible in digital video because the digital allows the complete programming of the image and each pixel is susceptible to manipulation.

This fragmentation is taken to the production too. Each video recording is made by a different person using a camera phone. I’ve established a general set-up to control the visual aspect of the image and each person should comply with it. In this form of production the final outcome is made by the work of a crowd. In my (self-)portrait there are authors and I act as a catalyst for the making of the video portrait. My role as an artist is to create the conditions for the production, nothing remarkably new since all post-industrial production functions in such a way. But this work is about the production of a portrait, something intimate and full with authorship. Expressed mathematically, each column of one pixel in my portrait is a function of one independent variable: you multiplied by a constant: me (γ).

Thus,  f(you * γ)

self-portrait (2012)

Self-portrait (2012)

The individual portrait was a Renaissance invention and it has been popular in visual arts since.  Today, a portrait is still described by the stylistic rules of the Renaissance portraiture. In this kind of depiction we observe the subject either in profile or in frontal position; and his or her eyes, nose, and mouth are easily identified as such. We have an idea of how the governing elites of the courts of Florence and Venice looked because they had themselves portrayed. The purpose behind these depictions was always the same: to make the subject identifiable and recognisable as the ruler.

The advent of photography facilitated the production of portraits at an individual scale and made them portable. Nowadays, one of the primary devices for identification is the ID photograph that can be found in ID cards and passports. The style of these photographs is always the same: frontal position, lack of gestures and headdress, and neutral background. Contrary to the Renaissance, the portraitist, photographer, is not necessary as this style is embedded in the photo booth. This style allows to thoroughly measure the face of an individual. The distance between eyes, dimension and position of the nose, width of the mouth, height and breadth of the face, and all other sort of physical features are documented. The aim of this process is the certain identification of each particular person. The modern systems of control in public places like airports and government facilities largely depend upon the boring ID portrait.
