Watch the room change

The light in a room is not a fixed quality. It shifts with the weather, the season and the time of day. An early conversation about how a space is used can reveal which of those moments matter most.

A useful starting point

Choose an ordinary activity and notice how the room supports it at different times. A morning breakfast place and an afternoon reading spot may need different qualities of light. Record what already works, what becomes uncomfortable and whether another nearby place is used instead. These observations provide a useful starting question; they do not replace a site assessment or establish a technical daylight result.

Make a short light diary

Use a few consistent observations instead of trying to capture every change. Note the approximate time, weather, activity and the place from which the room was observed. Include an ordinary overcast day as well as a bright one if possible. Ask whether a difficult moment happens regularly or only in unusual conditions. A small record makes it easier to explain the experience to another person without turning one memorable photograph into a conclusion about the whole room.

Photograph the context as well as the effect

A close view of a bright surface can hide the relationship between the opening, the room and the activity taking place. Add a wider view when it is appropriate and safe to do so, with permission from anyone whose space is shown. Cameras adjust exposure, so an image should not be treated as proof of a particular lighting level. Keep the photograph beside the written observation and use both to identify what should be examined in the actual setting.
