WebJan 13, 2024 · Though scientists have made strides in improving our representation of a “standard observer,” the 1931 2-deg colorimetric observer is still the dominant one used for making lighting calculations today, simply due to the inertia that must be overcome to change metrics. WebThe CIE originally defined the standard observer in 1931 using a 2 field of view, hence the name 2 Standard Observer. In 1964, the CIE defined an additional standard observer, this time based upon a 10 field of view; this …
