Video: You've probably seen those fun time lapse videos that make subjects look miniature, like toys or models surrounded by a realistic looking environment. This style requires a tilt shift lens, but this tutorial shows you how to create the effect without one.
The tutorial is via Rob & Jonas' Filmmaking Tips and explains the step-by-step process of creating a "tilt-shift effect". It will tell you how to shoot the footage to optimise it, then explain how to process it in Final Cut Pro. As PetaPixel points out, the tutorial emphasises the grain and saturation in post-processing, which makes the effect more effective.
... you can "trick" your viewers into seeing the result as a miniature world and not just a regular image with blur attached. You're trying to make it look like this is a scale model, and we're used to scale models (toys in general) being colourful and vibrant, not dull and muted like our world often is. Ignore this advice at your own peril.
If you use Premiere instead, this video tutorial explains how it's done, using the same overall process but with Premiere's options. For more detail, check out the video in full above or head to the link below.
