... for ICC stuff we're asking the device to report data based on the
2-degree, not 10-degree Standard Observer. Why?
A clue I found perusing the internet: To give an idea of what a 20
field of view is like compared to a 100 field of view, at a viewing
distance of an arm length a 20 field of view would be about a 2 cm
circle while a 100 field of view at the same distance would be about a
10 cm circle.
According to CIE documents I've read, the 2-degree data should be used
with the field of view is 4-degrees or less, and the 10-degree
supplemental data should be used when the field of view is more than
4-degrees.
So I guess the question is, what is the field of view of most of the
stuff we are looking at in the graphic arts? I'd say it depends on what
you're looking at and how you look at it. For more general use
10-degree may be more appropriate, but when "studying" our images, like
we have a tendency to do, 2-degree is probably more appropriate.
