Magic Lantern is a system for adding features to Canon DSLRs, Unified is a recent ML package enables some cameras to shoot footage that can processed to produce content with a larger exposure range – i.e. High Dynamic Range.
The files produced are made up of alternate frames of under- and over-exposed footage. My new generators take these frames and give you the control to define how the overexposed frames are overlayed on top of the underexposed frames.

December 2012: I’ve replaced the generators that were here with a single effect.
