Filming in low light was especially important for The Dark Knight Rises because a number of crucial scenes take place underground, including those in the Batcave. 
With  Wayne  Manorand  therefore  the  original  Batcavedestroyed  in  the  first film,  Bruce  Wayne  had temporarily  moved  his  base  of  operations  to  the  Bat-Bunker.  However,  the  mansion  was  rebuilt  with  the  inclusion  of  a  new  Batcave,  which echoes design elements of both earlier sets.   
Nathan Crowley,  who teamed with fellow production designer Kevin Kavanaugh on this film, explains, Chris and I pondered how to mix the Batcave and the Bat-Bunker, which  is  incredibly  geometric  and  modern  and  everything  is  cleanly  recessed  into  the walls.  It occurred to us that we could carry over the same idea by flooding the Batcave so everything is hidden underwater.  When you enter, its just a cave, but you  press a button and up come these perfect cubes that hold different objects, from the Batsuit to a super computer. 
Nolan offers, Its a terrific combination of the tactile reality of the Batcave and the functionality of the Bat-Bunker.
The Bat-Bunker  was  again  erected at  Cardington.    However,  the new Batcave set, complete with working waterfalls, was constructed on Stage 30 of Sony Studios  in Culver City, California.  The soundstage was ideal because it contains a water tank that can hold more than 720,000 gallons of water.
