Special effects have played a key role in moviemaking from the earliest days. History is repeating itself with the rise of mobile moviemaking. If you want a good example take a look at Matthew Pearce’s one minute and twenty second horror short, “Vengeance,” shot with an iPhone 4S.

The concluding effect is dramatic and impossible  to miss. But if you want to appreciate Pearce’s more subtle color manipulations, the filmmaker offers you a detail-rich behind-the-scenes featurette, which covers the gear he used in the making of “Vengeance.”

There’s plenty more where that came from at Pearce’s YouTube channel.
