Dans la continuité du travail mené par Thierry Guibert, Solaris rassemble la question d’une temporalité en permanente évolution, linéraire certes, mais défragmentée. Solaris est un projet qui crée des disques graphiques, lesquels, lorsqu’ils sont mis en mouvement produisent des images mobiles interprétées également comme sons. À l’intersection de l’ombro-cinéma et de la performance sonore, ce projet questionne le disque comme support mais aussi comme objet évolutif et visuel. La restranscription sonore ne peut fonctionner que lorsque le mouvement est engagé, ce qui, d’une certaine manière confirme par l’inverse la mécanique opérée dans les “Enveloppes Temporelles”. Ainsi, le mouvement révèle, rend visible une part fugitive, immanente et propre à l’oeuvre.

Si Thierry Guibert est un plasticien inscrit dans le champ des arts numériques, sa démarche s’appuie sur une analyse et une culture de l’image, plus particulièrement celle du cinéma. Ce nouveau travail : « Enveloppes temporelles » consiste en la captation globale d’un film et vise à retranscrire sa totalité en une seule et même image. Celle-ci prend la forme d’un panoramique et s’étale sur plusieurs mètres. Fondé sur la technique du slitscan - procédé consistant à analyser et assembler des tranches de pixels de façon récursive les unes à la suite des autres - Enveloppes temporelles retourne l’enveloppe du film pour en révéler, de façon fantomatique, sa part invisible. La temporalité est subitement altérée, déroutée, le mouvement n’est pas figé mais au contraire fait l’objet d’une révélation, une transformation permanente incapable de fixer l’instant.

Street-Scape aims to visualize the density of the people and their movement speed in the urban space.
The walking direction of people in the street is plotted in one direction to make their relative distances between each-other more apparent. All static objects are blurred creating an ambience of the environment while making the moving ones more visible. The people walking 5km/h have original proportions. Everyone moving faster is thinner and everyone slower respectively wider.
Street-Scape renders the people anonymous while revealing their demographic qualities such as their approximate age and gender. Thus, showing the relative amount of children, grown-ups, older people, bikers, etc in a particular place during the visualized time.

The Nordland Railway (‘Nordlandsbanen’ in Norwegian) celebrates its 50th anniversary this year. The railway is 729 kilometers long, and passes thorugh spectacular scenery, varying from the fjord area around Trondheim in the south, through beautiful valleys, over mountains and along fjords before crossing the Arctic Circle at Saltfjellet and descending down to the coastal city of Bodø.
Following the success of the world’s longest live documentary, Hurtigruten minute by minute, the Telemak Canal and Bergensbanen minute by minute, the Norwegian Broadcasting Corporation set out to film the Nordland Railway as well. This time, though, we had to think up a way to show the contrasts one can encounter along the route; the weather, colours and climatic conditions.
The solution was to film the journey once every season, to show the different weather conditions and the great changes in nature’s expression from summer to authumn, and winter to spring.

Watched "2001 : A Space Odyssey" last night. Set myself a challenge of finding a way to recreate the trippy stargate sequence before the film finished. :)
The original used slit-scan photography, something that was also used for the 70s Doctor Who Intro (that vid. is fascinating, about 9:00 in for the slitscan bit.)
Used Blender. Set up two elongated meshes set with a video texture, and flew a 360 degree pano camera along a linear path between them. The video was one I created with Processing.py from the bus tracking data (see previous image)

People and trams and cars and buses and vans passing Senate Square.
The white and green stripes in the background are the white walls and green roofs of the Lutheran cathedral.
Slower things (people) appear wider, faster things (trams, cars, buses) appear narrower. Some people wandered across the square and back, and appear twice.
Made from the central pixel-column of the frames of a four-and-a-half minute video (30 fps, 1920x1080), filmed on my phone in a homemade Lego stand. (Then ditched 1919/1920 of the video.)
low tech DYI experiment- a long exposure; taken through a slit in one end of a box which moves slowly across the frame
Time goes left to right, although the view was out the starboard side of the plane and we were heading east. Full size.
Taken with a slit-cam adapted from a simple point and shoot camera. The shutter was wedged open using a piece of plastic tube and some blu-tac, and a 1mm slit, made from black card, was mounted at the film plane. The cog-wheel which normally engages with the 35mm sprockets was taped over, thus fooling the automated wind on into keeping running for about 4 seconds each time the shutter release is pressed. The camera, an Olympus Trip 300 (£1.25 from a charity shop), has a slide across lens cover which is ideal to keep light out of the lens between exposures. I calculated that with the film moving at 60mm per second (measured by videoing the film winding then counting the perforations) the 1mm slit gives an exposure equivalent to 1/60th of a second. The 34mm lens has a fixed aperture of f5.6, so with ISO 200 film, the exposure was just right for an overcast late autumn afternoon. The first film was really just to see if the concept worked, next I plan to select places and subjects that should give interesting results from this technique.

This time it takes standard width frames rather than strips which were several frames wide.
The shutter was wedged open using a piece of plastic tube and some blu-tac, and a 1mm slit, made from black card, was mounted at the film plane. Each time the shutter release is pressed, the motor winds on one frame, in the process moving it past the slit and making the exposure. Each exposure takes somewhat less than a second. The camera, an Olympus Trip 300 (£1.25 from a charity shop), has a slide across lens cover which is ideal to keep light out of the lens between exposures.
The camera was held still during this exposure.

We were going for a shot of Fidel Castro, whom we spied biking in San Francisco. Reference the next shot in the sequence by Minnehaha Creek (aka Julie J): Viva Fidel!

(I'm not sure if these are really slit-scans or just examples of strip photography, please correct me if you know!)
Normally photographs show space in the two dimensions. Videos are similar, but with an added time dimension. These images ditch one of the space dimensions (up/down or left/right) and replace it with time, so in each you can see how the scene changes over time, but in a single image. It's similar to how they do photo-finishes at races.
Each was composed by first breaking a 25fps video into into its constituent frames.
For the bottom-left image, a thin central, *vertical* slice was then taken from each frame and then placed *left-to-right* to get the final image.
The (messy) top-left is the same, but the slice was *horizontal* and placed *top-to-bottom*.
For the bottom-right image, a thin *vertical* slice was taken from the very left edge of every frame and put on the very left edge of the final image. Then the next vertical slice was taken from every frame and placed to the right of that. This is repeated until the right edge is reached.
The top-right is the same, but *horizontal* slice were placed *top-to-bottom*.
We're so used to seeing space in the usual two (or three) dimension that it can be confusing to see one replaced with time. The bottom-right image shows the tram speeding up because it was moving slower at the left and so it was caught in more slices than on the right. But the bottom-left is more confusing: why is the tram "backwards"?

A video of slit-scan photos. Look out for the blue and yellow signs and the pedestrians.
Each frame is slit-scan photo showing a narrow slice of space across time, instead of a larger space in a single moment of time.
First this short 25fps video is split into its constituent frames.
Then a new image is created by taking a narrow vertical slice from the very left hand side of every frame and placing them next to each other. (In this case the slice is 4 pixels wide, to maintain the total width.)
Then a second image is created by taking the next slice to the right from each frame and lining them up.
This is repeated until the right hand side was reached.
These new individual slit-scan images show both time and space, but are then all animated to create this new video where time and space are in the wrong places, so the tram is going in the same direction, but backwards.
