Fill-in Flash

Use fill-in flash when you want the flash always to fire, regardless of the light conditions. For example, if the subject’s face appears dark in front of strong backlighting, if a tree or other large object is casting a shadow on the subject’s face, or when shooting under fluorescent or other artificial lighting to achieve the best color reproduction, you should use the fill-in flash mode. However, the flash could lose its effect when shooting a subject in extremely bright light. Use exposure compensation or use spot metering to meter the light only on the part of the subject that you want to shoot. (➞ 78)

Red-eye Reduction

To prevent the occurrence of the red-eye phenomenon in the eyes of photographed subjects, the

camera fires 10 short burst flashes to contract the pupils of the eyes before the main flash fires. 6 When you use this flash mode, there is a 1 second delay before the flash fires after full-pressing the shutter button, so make sure that the camera is steady. Red-eye reduction may not always be completely effective for the following reasons:

-The subject was not looking directly at the camera when the flash fired.

-The subject was not looking at the camera when the preliminary flashes fired.

-The subject was too far from the camera.

-Differences among subjects in their physical reactions to the preliminary flashes.
