Nuke - Realistic Depth of Field Defocus. Complete Guide for CLEAN edges!

Here's a complete guide to setting up ZDefocus and Bokeh to achieve realistic 'depth of field' (DOF) defocus effects for VFX and animation in Nuke. Lets compare ZDefocus, Bokeh, PxF_ZDefocus and PxF_DeepDefocus nodes to see which one is the best tool for creating DOF effects with CLEAN edges and fast render times. More information about PxF_ZDefocus here:    • PxF_ZDefocus   More information about PxF_DeepDefocus here:    • PxF_DeepDefocus      • PxF_DeepDefocus - New features in v1.1   Don't forget to install Pixelfudger gizmos! http://www.pixelfudger.com https://www.nukepedia.com/gizmos/filt...
