These patient room doors are inside the Babcock Building at the South Carolina Lunatic Asylum and were shot with a 24-105 zoom.
Before and during dawn inside buildings, I generally shoot with my 17mm tilt-shift or a 17-40, because I want wide angle shots of the space glowing blue from twilight. After the best light subsides (or once I've made a full pass through the building) I usually put on a 50mm or 24-105 to get in tighter with some detail shots.
This doesn't always work, because sometimes I'm limited to the amount of time I have to shoot somewhere, but when I have ample time, it's my favorite way to shoot.
