Viewing Condition Check and Setting
Compare the reading room configuration established as optimal with
the actual one. If differences exist between this configuration and the
actual one, adjust the room configuration to match that shown in the
drawing. For example, if desk lights were described to be turned off,
turn them off. Or, if the curtains were described to be closed, close
them.
You need a calibrated luxmeter with a minimum resolution of 1 lux.
To set optimal viewing conditions
• Turn the lights off and close any doors and windows to make
the room as dark as possible.
• Turn on the displays at least 30 minutes before starting
the measurement.
• Position the displays used for reading digital images in optimal
conditions.
• Reduce to the minimum any lighting coming from other sources,
such as view boxes, overhead or task lighting, to reproduce typical
ambient lighting conditions that would be set for reading digital
images on the Dome display.
• Check that the ambient lighting is stable; that is, there are no
flickering effects due to any of the lighting sources that are
turned on.
