Studio photographers emulate the effects in controlled surroundings by lighting still-life products with an overhead softbox; and portraits with a direct light source from an angle overhead. Natural daylight is the dominant light source used for most architectural photography, both exterior and interior. The way to gain the best understanding of weather patterns is to monitor television weather reports and forecasts daily. All the photographer needs is a few short bursts of sunshine to create a lasting impression on film. The job of the architectural photographer is to use the effect of direct sunshine on an elevation of a building to reveal texture, richness of colour and perspective through the interplay of the areas that are brightly lit with those that are in shadow. In photographic terms, clouds can be seen as giant reflective filters, both diffusing the sun and skylight passing through them, and acting as massive reflectors at the same time.
