Presentation Transcript

  1. Fabrication Readings: Theory Text Ch. 10, Walter Benjamin “The work of art in the age of mechanical reproduction”

  2. Image-making & thinking about images • objectives & practices, materials and techniques of image-makers • http://www.caiguoqiang.com/

  3. Paul Klee-- Taking a Line for a Walk

  4. Klee (continued)

  5. Klee (continued)

  6. Bridget Riley--Movement in Square

  7. Bridget Riley • Blaze

  8. Mitchell--Electronic Tools, • Problematic nature of “tool” in communications research • Digital Images and Manipulation as Challenges to authority of photographic records • Rethinking conventions in visual discourse

  9. Terminology • Capture Processes • Analogue photography • physical-chemical process • Digital image capture • electronic • Filtering • Sampling on grid locations • Quantization (converting samples of intensity in a finite range process)

  10. Pixel Values • Relation • To artist’s production • To “scene” or thing or phenomenon depicted

  11. Spatial and Tonal Resolution of an Image

  12. Pixels as Signifiers • About relationships, context • Prominent pixels -- create tensions between process and objects of depiction

  13. Data Interpretation Using color coding schemes • Images of Mars (Mariner IV data) • http://www.solarviews.com/cap/mars/mar4geom.htm • Roots in artistic systems (ex. Paul Klee)

  14. Paul Klee-New Harmony

  15. Digital Imaging Technologies (Mitchell) • Fundamental change in visual discourse? • Memory and display • Print vs. screen image • 3-D • Interaction Early head-mounted display in research on simulation (virtual reality) by Ivan Sutherland at Harvard, c. 1967

  16. Virtual Worlds?? Actively inhabit and interact with images in ways not possible before • Photograph by Robbie Cooper (New York Times 2007)

  17. Other Directions--visualization of mouvement (scientific research) • Link to Pixar mathematical research on simulations of movement for Ratatouille

  18. David Hockney on uses of technology by “Old Masters” • Camera Lucida (an optical aid)

  19. Artist Using Camera Lucida

  20. Hockney with Camera Lucida

  21. Giotto

  22. Masolino-- Healing of the Lame Man and Raising of Tabitha

  23. Hockney’s Collage of the History of the Use of Optical Aids by Artists

  24. Galison on Scientific Image-making & controversies • Competing systems for gathering information and analyzing it • Tensions between visual images and other ways of knowing • Example from Marontate’s Digital Dialogues Team (R. Karsten’s oceonographic research)

  25. The Motion of the Ocean:Imaging Ocean Currents and Environmental ChangesRichard Karstenrkarsten@acadiau.ca Digital Dialogues: connecting in art and science 18 September 2003

  26. Images of the ocean … Waves The beach. Tides

  27. Oceanography … heading out to sea Atlantis, 1931-1964 WHOI WHOI Cruises

  28. Cruise Results (from Pedlosky 1987) (Fuglister 1963)

  29. The wind driven ocean currents

  30. A new view from Satellites TOPEX/Poseidon launched 1992

  31. The wind driven ocean currents from altimetry

  32. Australia Theturbulent ocean the ocean is full of eddies satellites allow us to see and quantify the effect of these eddies L H CCAR Real-Time Altimeter Data Research Group

  33. Getting a 3D Image

  34. Argo data

  35. The Southern Ocean is warming Difference between recent ALACE Float data temperatures measured from 700–1100 m and historical mean temperatures. Gille, Science 2001

  36. Follow the fresh water Salinity

  37. Ocean images Photograph taken from space shuttle showing the Indian Ocean.

  38. Ocean images Enhanced sea colour images showing the coast of B.C. Provided by the SeaWiFS Project, NASA/Goddard Space Flight Center and ORBIMAGE.

  39. Ocean images

  40. Colouring science? data showing something? use colours to represent complex data scale chosen to emphasize result further emphasize by comparison

  41. The thermohaline circulation I

  42. The thermohaline circulation II (Schmitz 1996)

  43. Catastrophic climate change(www.whoi.edu/institutes/occi/currenttopics/climatechange_wef.html) R.B. Alley, from The Two-Mile Time Machine, 2000

  44. Conclusions oceanography has become a science of data and thus images digital images are changing how oceanography is done images can enhance or obscure good science
