Dynamic range
The span between the brightest and darkest point a camera can still render in one image.
The human eye adjusts to brightness continuously. A camera cannot: it has a fixed span between “still detail in the shadows” and “already blown-out white”. That span is dynamic range, measured in stops.
For 360° captures this is especially awkward, because there is always a window in frame. The interior is dark, outside is bright — and both sit in the same capture. Without sufficient dynamic range, either the window becomes a white surface or the room becomes a black hole.
The usual remedy is HDR: several exposures of the same scene, computed into one image.
