Design a Museum Display

For this project, you'll design a museum display that conveys how light, color, and spectra are used in art conservation.

Hokusai IR Imaging Part 3: Identify Blue

Investigate. Compare how the painting appears in natural light (No filter), with a blue filter (440 nm), and with an IR filter (905 nm).

  1. Use the No filter / 440 nm / 905 nm buttons to toggle between the visible light image, and false-color images taken with a 440 nm (blue) filter and 905 nm (infrared) filter.
  2. Based on the filtered images, identify the likely pigment in B3.

Spectrum Notebook. Answer the questions in your notebook.

  1. What pigment do you think is used at ROI B3? (If necessary, use the data in the Spectrum Tool below to remind yourself what pigments make up ROI B1 and ROI B2.)
  2. What clues did you use from the filtered images to identify the pigment at ROI B3?
