The screenshots on this page illustrate some of the lighting work I have contributed towards the Catwoman's Revenge DLC for Batman: Arkham Knight.

Initial first lighting pass was done by Florian Desaunay

I was responsible for taking this level to final quality lighting.

All the lighting in Batman: Arkham Knight is realtime lighting.
