should lower the ambient light level to a range that is compatible with your monitor.
Critical color work requires an environment where the ambient light is consistent and
at low to moderate levels.
Advanced Topic: Surround
Another area worthy of attention is the monitor Surround. This is the area of the
room that your eyes see in their peripheral view while you are looking at the monitor.
The Surround should be smooth, neutral in color and dimly lit.
If the Surround is brightly colored or brightly lit this will influence your perception of
color and tone on the monitor. Viewing the same image with a different Surround
condition may result in a different perception of the image. Including exterior windows
in the Surround area causes variable influences on the eye, as well as glare and eye
fatigue, and should be avoided for any long-term or color-sensitive work. Covering the
wall behind the monitor (including any windows it may contain) with an opaque,
medium gray cloth is the best solution to situations where the wall color, brightness,
and windows, cannot be otherwise controlled.
Advanced Topic: Luminance and White Point
Each ambient light level has a recommended White Luminance that is based on
keeping monitor brightness high enough for good perception of the full display range,
and avoiding White Point adaptation by the eye to whites in the Surround, instead of
on the monitor. If the monitor is not bright enough (or conversely, the ambient light is
too bright), room lighting will reduce the eye’s acuity and ability to distinguish shadow
detail on screen. If there are bright areas in the Surround brighter than the white of
the screen, the eye may adapt to the White Point of the surround, instead of the
display, causing the display to appear both dim and off color.
Each ambient light level has a recommended White Point that is based on the eye’s
differential response to color with increasing luminance. In darker conditions, the Rods
in the eye play a larger part in vision. The blue cast the Rods incorporate into vision
mean that under low light conditions, a warmer monitor White Point is required for the
