Set the flash to flash off to bring out the atmosphere of a room
Close to windows where the light shines in, the light from the outside is brighter than the light inside. A picture taken in this type of setting will result in the subject appearing silhouetted. Using the flash illuminates the subject. However, there are times when this causes the picture to seem unnatural, with the subject appearing too bright or a deep shadow appearing in the background. In such cases, set the flash to flash off and adjust the brightness with the exposure compensation to take the picture.
