Yes, I also would think there's a difference between judging a large area of uniform color and the small areas (less than 2 degrees) of adjcent colors in an image, where simultaneous contrast comes into effect, so 2 degrees would be most appropriate for the latter.

If they were single colors there would be no context and therefore would not be a realisitic way of determining the experience of color. I’m curious about the observer conclusions and what can honestly be said about them. Whether from 10° or 2°, does the observer test have a some weaknesses - maybe a lot of weakness? It seems to me that the matter involves relying on “the best we have” even though it isn’t the best it could be. Henry Davis

Hi Jan-Peter,
but you will not judge the complete monitor image at once nor will you judge the complete magazine. You typically focus on a smaller area and then change your focus. Think of how you make a proof-to-print evaluation.
Best regards

Hi Claas, Thanks for your explanation. I made your simple test, and even my Laptop monitor is bigger than my fist. Same for looking on a double sided magazine with photos.
Should we change to the the 10° observer for the printing industry? Whats about defining the printing industry as being part both of the media industry and a technical process for coating surfaces?
Both industries are using 10° observer for measurements...
Best regards Jan-Peter
