I am an architectural photographer preparing to shoot a new, modern five story, squarish university building with a clerestory atrium in the center going from the basement all the way to the roof with stairs and balustrades, and sitting spaces all around it on each of the four sides. The lighting is all over the place. On the west side of the building there is natural light filtering in through windows. (I can shoot at night, during the day, or both). There are tungsten can lights on the balconies, colored lights installed in some of the railings, and a media screen installed in the atrium against one side that affects three stories and will be running constantly during the shoot. The media screen is luminous and spills color everywhere . There are fluorescents in the offices seen through glass panels in the background of every shot that are showing green in the scout shots.
Usually with the camera set on auto white balance, I put a gray card in each shot, or a MacBeth checker, then use the LR WB dropper, tweak that result if necessary and copy the color temperature I decide on into each file in LR. I don't know what to do here, or even where to put a checker. Is there a way to determine a custom white balance color temperature for the whole atrium - all five floors? Or maybe one for daylight shots and one for night shots? Should I try to create a camera profile with Passport (don't use that normally)?
Any suggestions would be appreciated, especially if you have experience something similar and solved the problem. I want to avoid endless tweaking in post to try to make them all consistent.
