Filters have an important role to play, especially when photographing indoors with artificial lighting. Tungsten lamps give a brown cast to the images and fluorescent lighting is typically green although it can vary. Lighting building interiors and exteriors is extremely complicated. The exterior shots are normally taken in daylight, however, there will be a right time of year and hour of the day when the sun is in the best position to bring out the texture and detail in the building. A careful study of the building and the path of the sun will identify the best time to photograph it.
Many buildings now have flood lighting installed making shooting in the evening feasible.
The best time to do this kind of shot is sunset or dusk when there is still some colour in the sky and some ambient light which prevents the background from going black and giving some detail in the shadows. The interiors of buildings can be as awkward as the exteriors because the illumination is not designed for film. Bright sunlight streaming through windows and dark murky corners creates a large amount of contrast which film cannot cope with easily. Clever use of reflectors and fill in flash are generally adequate in small rooms but larger areas may need a complex arrangement of studio flash equipment to ensure fairly even lighting throughout. Bright sunlight is a problem that can be overcome by waiting for a cloudy day or covering the windows with tracing paper to cut down the light.
