afterimage – session 1 “a homage to la jetée”

Wednesday, February 24th, 2010

time and light are keyconcepts for our perception of the world we are living in. when we look at the stars in the nightly sky we seem them glooming bright and alive. but most of the stars we see have already died aeons ago. light, compared to the size of the universe, is slow and needs a long time to travel the far distances from the rims of the universe to our small solar system. what we see is an afterimage of the stars frozen into the firmament. when starring into a bright light source a similiar effect happens. our receptors in the eyes are lamed and cannot receive new input for a short time. so when facing the sun for a certain amount of time and then look away we can still see the bright disc dancing in front of our visual perception. it’s like going backwards into time.

not only light is slow, also our consciouness walks behind reality. when we decide to move an arm, take a step, form a word or just look at something, our subconscious awareness has already made this decision for us. therefore one can say that we live in an afterimage of our subconsciousness. what if anyone is aware of this afterimage, though perceiving the world through the channel of the subconsciousnes. he would be a timetraveller to his
surrounding being one step ahead of our time and space continuum.

the installation is placed in a completly dark room. at one wall a screen is attached that shows altered frames from the movie “La Jetée”, by Chris Marker from 1962. the pictures are not visual on the screen all the time, but flashed onto the retina of the observer. according to the pictures, dialogue lines taken
from the movie sound in the room. the installation tells its own story and though let the movie appear in a new form. because of the fact that the visual part appears different on the retina for every observer a personal interpretation of the story will be given for the visitor.

afterimage 3 – getting close

Wednesday, January 20th, 2010

after some fooling around with methods on how to get done with the technical realization of the project it’s now narrowed down. the installation will use the screen part of an 14” tft monitor, which makes it easy to apply the pictures directly from a pc. furthermore the tft has build in audio speakers which will be used for the sound.

to flash the pictures from the screen onto the retina i’ll be using a photoflash. for the flash to be executed at the right time i am using puredata, which will play the image sequence and sound and is also sending a trigger at the right time to a duemilanove arduino board with an 328 microcontroller chip, which is wired with the photoflash. the script on the arduino is short circuiting the flash to trigger it whenever i say so. by using an optoisolator i’ll be on the safe side not to overload my precious arduino board. thx to riblbem for this wonderfull tutorial!

using pd gives me two advantages. first i can sync the flash with the pictures pretty easy and second i can synchronise the sound to, but still leaving every component discrete though beeing possible to alter them afterwards.

as you can see the setup is pretty simple and so are the scripts, what’s now left to do is to build a decent frame for the tft screen and think about how to attach the flash to it. i also have to find a way how to spread the light of the flash over the whole screen, which maybe works by just putting a sheet of thin paper between the two, but that’s just testing. the tougher part will be now to write the storyline, but that will be the task for next week!

afterimage 2 – installation concept

Thursday, November 26th, 2009

all we are going to do is predefined, not in a spiritual but a subconscious way. our brain already knows when we want to move our hand, go left or right, look at a certain direction or think of something, just an instance before we do it. this scientific fact raises questions about fate and free will. are we free and conscious beings or just slaves of our subconscious mind?
this also questions the structure of time we live in. how can we say to live in the present if our actions and thoughts have already been defined a mere moment ago. as a consequence we have to accept that everything and everyone actually lives and acts in the future, or the subconscious present. therefore all we experience is just an image of the past, an afterimage of ourselves.

what if someone really experiences life in this future frame of time? what if all actions are percepted ahead of time and can’t be undone? this installation tells a story of a man who is trapped in such a twisted form of reallity.

the audio/visual installation consists of a box which has an opening on one side. it’s complety dark inside, a piece of cloth is shading the light coming from the outside. a loudspeaker inside the box is telling the story in a form of an inner monologue. opposite of the opening will be a monitor that flashes pictures according to the storyline. the pictures will only remain for a moment following a dark pause of some seconds. the viewer will see an afterimage of the displayed picture inside the darkness of the box.

I will wake up in a minute. My eyes will open, I will see the light coming through. My dreams will be vanished, my body powered up to full operational mode. All this will happen, already has happened. I still sleep, but I’m already awake….
