Ok, I’m surprised I did not manage to get it was a real one, some DoF effect seem off to me even though it’s a real tilt shift image ^^
This miniature effect I guess ? Best shown when taken from higher ground :
I took this one 10 Y ago, and this is a genuinely fake one 
no tilt shift equipment what soever involved, just gimp with a basic dbl gradient mask on a focus blurred version.

I always though that if I had taken the time to properly adjust the mask to take in account the real 3D of the scene It could be better, but then again maybe not …
