A mid-block rowhouse kitchen has no window, so the light rides in the van
The house type that defines the District decides what has to be on the truck before anybody films anything.
A rowhouse is deep and narrow, with glass at the front and the back and nothing in between. The kitchen usually sits in the middle. At noon in June that room is dark, and in January the working day ends in the dark as well.
Waiting for good light in a rowhouse means waiting for something that is never arriving. Two battery lights and a stand travel with the crew, and the room gets shot with the same setup on every job so a warm white cabinet reads the same in December as it does in May.
Set the white balance once and leave it alone. A kitchen in the middle of a Capitol Hill rowhouse has no daylight to balance against, so whatever the camera decides on its own will drift from job to job and your finishes will look like they drifted with it.
The same fact is worth saying out loud to buyers. Owners on those blocks have lived with a dark middle room for years, and what they want to know is what can actually be done about it. A room lit honestly rather than lit to flatter is the version they can believe when they walk into it on the first morning.
