You already know the moment.
You've flown in with the gear. You get to the room, and the overhead is one warm yellow bulb, off-center, right where your subject needs to stand. The window faces a wall. There's no proper corner for a softbox and no room in the case for one anyway.
So you compromise. You shoot toward the window and hope. You crank ISO. You spend an hour in post trying to save skin tones that never had a chance.
