Learning Objectives

This workshop introduces some experimental media practices that arise from using devices to "capture" the world. In particular, we are concerned with how we can understand and build representations of the world using devices that sense beyond the limits of human perception.

Monday

1. Introduction. Meet & Greet; Discussion & Objectives

   • Tomography and Holes in Swiss Cheese; "Mechanism and control of the eye formation in cheese" paper, paper, e.g. "There is demand for non‐destructive monitoring of eye formation in cheese during ripening.", [PDF]

2. A quick, incomplete list of some hands-on stuff we'll cover:

   • 3D scanning and Photogrammetry
   • Multi-spectral imaging (NIR, UV, Thermal)
   • High-speed videography and other temporal play
   • 360-degree video
   • Gesture capture & OSC
   • Binaural & ultrasonic audio

3. Appetizers

   • What is a Camera? Conceptual Cameras
   • Perspective Capture and Representation

Main Topics: Multi-spectral and High-speed imaging.

Today's topic is seeing beyond human perception, with: Multi-spectral imaging (NIR, UV, Thermal) and High-speed videography. Lectures include:

• Multispectral & Hyperspectral Imaging
• Overcranking (Slow-Motion/Hi-Speed)

Activities and Exercises

1. Demonstrations of UV, IR, Thermal (FLIR & Axis) imaging. Also: Thermochromic, phosphorescent, retroreflective, and polarizing sheets and surfaces.
2. Demonstrations of the Edgertronic high speed camera. Here's the Edgertronic Beginner's Guide to High-Speed Video, and their Quick Start Guide, which may be helpful if you want to know more.

Auxiliary/Secondary Topic: Audio

• Binaural recording
• Ultrasonic recording
