Layering projections



Original Video (Tina Zacharia) also found at:


Following my prior studies and experimentation with varied materials, the most successful in transmitting light through layers has proven to be the medium gauze linen; excellent in allowing for fluid movement as well as the ability to be pulled taunt. The above video illustrates the diffusion of image projection through the 3 hand made screens.

Riot Iconography - "Layering the loop"


Coke? Riot icons - feeding visually stimulating imagery within the loop

Researching into how visual stimuli (namely moving textual and flashing imagery) respond the feedback loop, I set up a sample reel in order to test various scenarios, alongside adapted setup (i.e height / angle)




Resultant stills are below:

1/ No Camera rotation



2/ Camera rotation - 90 degrees

  

3/ Projector displacement - 45 degrees




4/ Image manipulation (through player)

Visual feedback experimentation

Still image of set up: playback of footage of visual feedback: (photo: Tina Zacharia)

"Video feedback is the process that starts and continues when a video camera is pointed at its playback video monitor. The image from the camera is delayed slightly in time as it travels through the extensive circuitry of the recording system and then is output to the video playback monitor" Wikipedia

The natural progression of research lead the experimentation into visual feedback using an optical input (video camera) and optical output (TV receiver). Connecting the video camera to the AV socket and pointing directly to the monitor, light received is amplified and sent by the cable to the monitor, projecting electron beams. The image is then captured again and fed back to the monitor hence a continuous loop. The resulting images were dependant on the settings of both camera and monitor to include angle, focus, distance, contrast and brightness.

Photos and videos of results to come!!
