With rich support for multiple depth-specified samples per-pixel, deep images overcome many of the challenges previously faced when trying to combine multiple images using simple alpha channels and/or depth values.

In this talk from Siggraph 2018, Rob Pieké of MPC R&D shows that with a richer contextual understanding of the target composite, systems – both automatic and artist-controlled – can be built to significantly compress deep images such that there is no perceptual different in the final result.
