The iPhone does a good job of capturing color automatically. However, professional moviemakers have long known that getting the best color imagery requires tweaking colors—color grading—in post production. Traditionally, this has been the work of specialists called colorists. You can see a fascinating 3-minute video about what colorists do here.
Now, an upcoming FiLMiC Pro upgrade will enable mobile moviemakers to shoot footage that can be colorized during the editing phase. Soon everyone (who wants to) can be a colorist.
You’ll find a clear preview of the improved FiLMiC Pro app—plus before and after video tests—at 9TO5Mac. That blog also provides a 13-minute video overview of the current FiLMiC Pro’s features.
