Title: Have you seen this "miniature" video effect ?

The abnormally shallow depth of field and speed-up makes landscape look like a miniature model

Absolutely great!

I was watching the video thinking it was obviously a miniature and couldnt see what to get worked up about ... then I re-read your message! 

Thanks for link

The optical illusion works better with some viewpoints than others:
IMO the best shots are in the first two minutes of the video

A lot of people take photos of models they make with their expensive cameras, but they find the models don't look too realistic.

One method that produces much more convincing results is to use a pinhole camera, which is about as low tech as you can get  [:D]

An expensive solution to maximise the depth of field on a model set is to use camera with movements to tilt the plane of focus so it is parallel with the set. (the Scheimpflug* principle (http://en.wikipedia.org/wiki/Scheimpflug_principle)).

[* No I can't pronounce it either  [:)] ]

Waaaaa! MATH OVERLOAD.

I think I'll stick with the pinhole and a time exposure!

(I've never actually tried it, but I've seen some examples, and they are very convincing. I'll try to find some on the web.)

No maths necessary. Just extrapolate the image plane (the film back of camera) and the subject plane (the model set) to the line in space where these to planes intersect, then tilt the lens panel so its plane also intersects with this line in space  (the Scheimpflug intersection).

The difficult bit is finding the cash to buy a camera or lens with movements, which are horribly expensive.

Pinhole photography does have "infinite" depth of field but the results are soft focus because of diffraction ...

(also vignetting but that is correctable)
