DESCRIPTION:Dr Edward A Wilson\, a noted artist and member of Scientific S
 taff on two expeditions led by Captain R F Scott to Antarctica\, wrote abo
 ut the effects of the light emitted by an acetylene gas lamp on his percep
 tion of colour whilst painting\, commenting that the yellows and blues app
 eared different. This project proposes the use of hyperspectral imaging to
  measure the reflectance spectrum of the pigments in Dr Edward A Wilson’
 s watercolours to enable a calculation of the effects of acetylene gas lig
 ht on the perception of colour that is recorded by the composition (colour
  contrast\, distribution etc) of his paintings. The key to this analysis i
 s the spectral power distribution of the acetylene gas discharge\, which d
 epends on the mixture of gases actually used. To establish this a lamp of 
 the type used in the expedition has been set up at UCL to measure the spec
 trum of the light it produces\; other sources of light and fuel available 
 on the expeditions will be taken into account.\n\nThis project aims to rec
 onfigure the effects of the material and technological context  - acetylen
 e gas lamps\, the reflectance spectrum of watercolour pigments – on the 
 distribution and appearance of colour in Wilson’s Antarctic paintings. A
 s part of a material\, technological and social history of early 1900s Ant
 arctic expeditions\, the project recalls the experiments and innovation of
  the “Discovery” 1901-04 and “Terra Nova” 1910-13 Expeditions\, to
  form a new context for the analysis Wilson’s colour work.\n \nThe techn
 ologies and techniques that underpinned the production of the iconic image
 s of Antarctic expeditions led by Captain R F Scott  - including Ponting
 ’s photographs and Wilson’s watercolours - combined scientific and art
  practices in a cultural\, technological\, visual record that mapped the A
 ntarctic for public exhibition. The project proposes a form of non-destruc
 tive colour correction to offer a comparative image of the watercolours as
  they would appear under the light of the acetylene gas lamp in the Winter
  Base Hut and to further understanding and make apparent the material hist
 ory of exploration for an audience today.\n\nThere will be a short discuss
 ion about the project by Dr Liz Watkins (University of Leeds) and Dr Linds
 ay MacDonald (University College London)\, followed by a short presentatio
 n by Headwall's European Channel Manager\, Francesco Beccari and Isaac Gil
 bert (Analytik\, Ltd.) and demonstration of the Hyperspectral Lab Scanning
  kit complete with a VNIR Sensor.\n\n
