How exactly is the Flickr "look" defined?

View on HN

Flickr's resized images have a characteristically (over)sharpened appearance.

Does that mean that any artistic depth-of-field effect is (partially) eliminated by the Flickr look?

Ordinary image sharpening tends to just make existing edges look sharper; dof blurriness obliterates the edges. Strong sharpening on a strongly DoF-blurred image might actually make the visual contrast between in-focus and out-of-focus areas stronger.
