Synchro-Sunlight Fill-In Flash Photography
A backlit subject, such as a person outside with hislher back to the sun or indoors in front of a window, may come out almost as a silhouette if the background is correctly exposed . On the other hand, if exposure com- pensation is made to give the correct exposure for a backlit subject, the background may be washed out. To fill in the shadows and balance the illumination levels of the subject and background, you can use an electronic flash unit even in daytime.
One important fact to remember in balancing the expo- sure for both subject and background is thi s: Exposure with a flash unit is determined only by the aperture
selected, whereas exposure for ambient daylight is determined by a combination of shutter speed and aperture.
Without flash or expo- sure compensation : the backlit subject comes out too dark.
Without flash, but with the exposure compen- sation dial set at
+2: the subject's face is correctly exposed, but the background is too bright.
