At the Hawaii County Fair in Hilo in September 2001, the astronomy exhibit
was set up and operated by all the Mauna Kea Observatories (including the IfA).
IfA scientists Klaus Hodapp and Andrew Pickles, and Electronic Technician Darryl
Watanabe presented "Beyond the Visible: Infrared from Planets and People." This
interactive workshop used CCDs, infrared cameras, and liquid nitrogen to demonstrate
how common objects in a room, including people, emit light that can be imaged
with cameras sensitive to wavelengths longer than visible. Participants had
their pictures taken at infrared wavelengths and projected on the screen behind
them. The colder the object, the darker it appears.
