Well, it's been a while since my Internet video days, but hell, I love 3d parallax effects. When are we shooting?

Surprisingly well faked in face of the fact that there's no real 3D information in the pictures. There simply cannot be new 'pixels' appearing that were (i.e. before applying the effect) hidden from objects in the cameras line-of-sight. This is evident upon closer inspection (look at edges around the approximate middle of the DOF). The trompe-l'œil then falls a bit apart. Interestingly, I did not notice above with th…

Yeah.

Also, as the depth map only has a single depth value per pixel, you can get aliasing around the edges of the objects in focus as they have a halo around them.

Damn this is cool. Even though there's some smearing to make up for the lack of information, especially behind the railings on the deck, the effect is striking, and subtle enough to be believable at a casual glance.

I would be interested to see how this effect affects the conversion rate. I could imagine that it could work very well on physical products.
