- Welcome to part 2 of Alfie Vaughan’s series on adding realistic depth of field to a VFX shot. In this tutorial, Alfie demonstrates how to achieve the next level of beauty and realism in a cinematic VFX shot.
Some VFX shots simply demand a higher level of focal finesse than what’s achievable with the 2D data from a depth pass. For these shots, industry VFX artists use 3D depth data, or “deep”, where every pixel in the image has its own individual 3D depth data. This allows you to achieve ultra-realistic focal depths.
Although deep data gives you perfect defocus, it is costly in terms of time and hard drive space, so it may not always be the first solution. But if you’re working on a shot that really needs precise focal depths, and the standard defocus toolset is not giving you the accuracy required, using deep data with Nuke’s bokeh node is the way to go.
This tutorial is available in Ultra HD.

Simple way ro kill file sizes: just render a deep alpha (simply setting the color type to float in arnold for example).
You end up with normal file size and you still can use the deep data for dof and roto. + Everythings runs smoother again.
Great video, the tutor is insightful and eloquent.
Alfie is a great host!!
Awww thanks!
More tuts from this guy pls!! Really cool Alfie!
Thank you! :)
Great tut Alfie.
Thanks dude!
this is great but can we please get a refresh of the interface
hey guys thanks for the vid, but is there any mid level solution from this (regular beauty/depth pass to deep renders)? maybe i could get around this (mid level styled solution) using cryptomatte? any tutorial or mid level solution from foundry/nuke community? thanks and more power!
How to render deep pass in blender?
Currently Blender Cycles doesn't support deep passes.
