Remove Second Image
The typical misadjusted monitor will not show the image, due to the inherently low contrast. First image above is a useful example; seconfd image should be removed. algocu (talk) 19:50, 3 October 2008 (UTC)

Where's the Haidinger's brush?
I'm not sure if I see it or not. Is it like this little pinkish-orangeish thing in the centre of the page...? NoriMori (talk) 04:50, 28 October 2009 (UTC)


 * I do not think this image represents a good illustration of the effect. For me it is totally impossible to see at standard contrast. --193.50.110.41 (talk) 10:31, 9 July 2010 (UTC)
