Although tilt-shift lenses have many uses, one of the most common for timelapse photographers is miniaturisation. Tilt-shift lenses are expensive, though. Certainly worth the investment for things like architecture or products. But for most of us, who’ll only use it very occasionally, not so much. Most of the time, the look is simulated in post. While the tilt shift look is not new, this video from Rob & Jonas is probably one of the best explanations I’ve seen on reproducing it in the computer.
It’s not necessarily because of the technique or software used, but because Rob shows us exactly what miniature is supposed to look like. He does that by actually shooting something in miniature. In this case, Lego sets and characters. Rob reverse-engineers the look to apply it on a larger scale. It offers some valuable insight into both the shooting of it, as well as the post production.
