film techniques - How were the zooming sequences performed?

Limitless even opens with such a seemingly endless zoom shot better know as Fractal zoom, though the scene you referred to, is not endless, but is more of a fly-by zoom shot. Such effects are often rendered by processing normal footage (using cameras) using advanced video editing software (like Adobe After Effects) or customized code to render fractal zoom.



This interview here discusses in detail about the technology, technique and idea behind that opening shot for Limitless.



The article referred to, above says this about the software used




PCW: What kind of software did your team use for the effects?



Comen: The primary software we used was [The Foundry] Nuke for the
compositing, [Adobe] After Effects for the titles, and Maya for the 3D
graphics. Our team was a crew of about 20 people, including support
staff.




Another example of a really long fractal zoom can be found here on YouTube. This video, took 6 months to render!
