essential skills: photographic lighting
First exposure - exterior ambient light - exposure: MIE less 1/2 stop
Second exposure - total darkness - interior lights on - exposure: average highlights and shadows
Combined exposure
Double exposures A double exposure can be used to balance the bright ambient light and the comparatively dim interior lighting of a building. Some digital cameras allow for the multiple exposures, that are required to achieve this outcome, to be recorded in-camera. If the camera does not allow for multiple exposures to be made using a single image file, two separate exposures can be combined in post-production. To achieve this result the photographer must use a tripod and take care not to disturb the alignment whilst adjusting the camera to make the second exposure. If the camera’s white balance is set to daylight the interior lighting will record as a different color temperature to the exterior daylight. If the images are combined in post-production the interior lighting is placed on a layer above the exterior lighting layer. Set the interior lighting layer to the Lighten blend mode.
