Hi Guys, first post here so lets give it a shot, i had a look at Tom's reference image
and i notice two things, the ugly overexposure of the top window area that has nothing
to do with this whatsoever but just felt like mentioning it. and the horizontal lines in the
corners is straight up, which means there is a vertical shift applied to the vray physical
camera which might also contribute to the illusion of the tilt shift effect, Photoshop tilt
shift is not very versatile, the "Smallworlds Video" is a bit more complex and the blur
differs alot from scene to scene and photoshop just slaps it on there making it quite
messy, anyway I was bored earlier and remade a similar scene trying to mimic the effect
and post was done entirely with 2 additional Vray render elements, Extratex with dirt map
for ambient occlusion, and Zdepth that i used the most to enhance the environment
effect from the windows and the blur effect seen on the picture, didnt take long, was
just a test since i was curious. But usind Zdepth in post is very versatile and easy to use not to mention the render time saved.
