E3 demo, fans noticed the images looked a little too good to be true, drawing obvious connections to Killzone's infamous E3 2005 debut trailer, which substituted actual game content with pre-rendered 'target' video.
Guerrilla QA manager Seb Downie joined the discussion on the PlayStation Forums, admitting, "[The screenshots] are only the tiniest bit touched up ... there was a little bit of colour-correction done and some minor polish, but nothing major." The comparison image above, also posted in the discussion (via PSU), seems to corroborate Downie's admission, revealing sharper colors and deeper contrasts in the 'doctored' screen on the right (effects that seem within the limits of standard display settings; i.e., a television could be capable of displaying both the dull and stylized versions of this scene by tinkering with its display settings). Also, the "original" version of the image is a frame snagged directly from video, so it's subject to a certain amount of blurring that's not necessarily an accurate depiction of gameplay frozen in that instant. In any case, how can a screenshot ever tell the truth? Downie concludes that Killzone 2 simply "looks better in motion."
