The viewing size has an effect too

Thanks for posting your tests.

There is an interesting discussion of this at http://www.journalofvision.org/content/12/5/8.full and some quite good animations of the effect.

One point that doesn't seem to have been mentioned in previous posts (unless I have missed it) is the effect of the size of the image as seen by the viewer. Your examples images were posted at quite a modest size, but viewing them much larger would change the visual effect. The distortion apparent in portraits taken with a wide-angle lens looks more unnatural in a thumbnail image than in the same image filling a large screen and viewed from fairly close.
