“Our projection system is set up in an old limestone mine off the Dudley Canal Tunnel. A six minute video on the geology and history of the mine is projected onto a 5 metre screen and viewed by the audience who are seated on one of the Trust's electrically powered narrowboats. Although the temperature in the mine remains fairly constant, the humidity varies widely and can reach 100%RH. The highly alkaline environment is also very aggressive and we rely on our environmental enclosure to protect the projector from these conditions.”
