I was working with a "Crusescanner CS 220 ST" in the beginning of this year.
This scanner is made for reproducing and digitizing big paintings/artworks.
So it can capture an area of 1,20x2,50m! That is realy amazing! And the
resolution is absolutely brilliant! Great!
So at first I was doing some body-scanning and moving with the same iconography as on a flatbedscanner but it is really interessting:
Some results are on my page:
But these results are just some "quick and dirty" experiments!
My main idea was, to express a process - the scan-process. Because to capture a scan takes really much more time than taking a picture! So this
scan took 9 minutes: And that means, that the first scan-line is 9 minutes older than the last line. To show this difference I took a box with water and four bottles with color. And when the scanline has captured the first part of the area I could take
the bottles and fill the color in that water-box...and so the water gets colored because of this diffusion.
But the conceptional idea behind this is that you can not see this process in the reality: You can just see the beginning with a few color in the water
- but then the rest is still clear. And in the end, when the water is colored dark, the whole color is dark and not just a part as you see in the scan-picture. So this visual result can just be done by a scanner!
And another effect is produced by the moving color: Because this motion brings artefacts into the scan-picture. (e.g. Black white orange and red cannot mix blue green or magenta) it is an analogue/digital diffusion -
as the title describes!
My background is printmedia. So I am used to the digital image. For applying for the Academy of Media Arts, Cologne, I have to broach the issue of invisibility. Therefore I examine the relationship of time, movement, reflections and visual perception.
If the period of perception is expanded you get more visible information than in the „normal“ period. Or if you abbreviate the period you lose visible information. So the visual result is modified and the progress of this modified visual is an experimental one.
The scanner ist the optimal device for examinating the perception of movement. Because capturing image data by scanning enables to capture data in a modifiable period: the result is one sharp image. The result of photographing by time exposure is a blurred image, which is known for a long time. I like the high resolution and the lighting. Especially the light which is emitted by the scanner and is reflected by mirror finish is one of my main issue.
At the moment I extend my analysis of movement to the field of 3D-Body-Scanning.
How to scan ?
For getting images like these there are only a few steps:
A normal flatbed scanner and a scan-software is required. At first you have to darken the room and take dark gloves for your hands (maybe you also need a black pullover). Then you choose reflecting objects, like glass, plastic-bottles, mirror ball. You can also treat these objects.
What you have to do while scanning: move and turn your objetcs above the the scanning light in order to send the emitted light back to the scanner. That's all.
