Perceptible dynamics of the eye and extended dynamics in HDR display

If we look at the brightness dynamics, they range from absolute darkness to strong sunlight. Nit values for this brightness range from zero nits or candela per square meter in absolute darkness to `10^-2` nits in moonlight, 1 nit in candlelight, `10^6` nits in cloudy skies, and `10^9` nits in bright sunshine. Human vision covers the range from `10^-5` nits, corresponding to brightness in starry sky, to `10^8` nits, corresponding to brightness in sunshine.

Related to the illumination quantity Footlambert (fl), - a Footlambert corresponds to 1 Candela per square foot (cd/q-foot) - results in 3,426 Nits or 3,426 ` Cd/m^2` for one square meter.
