When you re shooting in total darkness or in dimly lit rooms, you have no other choice but to enable your camera flash When you photograph with a flash, you often wash out a picture because of the flash s harshness, especially when you re close to your subject With the exception of photos where detail is lost because you were too close to the subject when the flash went off, you can correct this to some extent by editing the image in an image-editing application You can also use your camera flash to fill in shadows For example, if you re photographing someone in a shaded area who has his or her back to the sun, or if your subject is wearing a large hat, fill flash can be used to lighten the shaded areas

PHOTOGRAPHING PEOPLE WITH FLASH
When you photograph a person, pet, or group of people with a flash camera, you may see a condition known as red-eye This occurs because the subject s pupils are dilated to cope with the dim light The camera flash bounces off the person s retina back into the camera, making a person s eyes look red and pets eyes look white If your camera has a red-eye reduction feature, the camera fires a pre-flash, which causes the subject s pupil to close down and avoid the dilation that causes the red-eye DEAL WITH RED-EYE
Use Advanced Flash Options
If you own a high-end digital camera or a digital SLR camera, you may have a flash hot shoe: an electrical contact that enables you to connect an external flash to the camera External flash units are generally more powerful than on-camera flash units With an external flash unit, you can use what is known as bounce flash With bounce flash, the external flash unit is angled toward the ceiling or a wall The resulting illumination is more diffuse and eliminates harsh shadows in areas such as under the subject s chin Shadows on the wall are also diffused, resulting in a more pleasing picture If you use bounce flash, make sure the ceiling or wall off which you bounce the flash is white; otherwise, you ll add a color cast to the image Another option for bathing a scene in diffuse light is to attach a piece of white poster board to the flash and swivel the flash upward at a 45 degree angle, as shown here The flash bounces off the poster board and bathes the subject in diffuse light Another option available on many digital cameras is night portrait mode, also called slow-synch flash mode When you shoot images in this mode, the flash records your subject and the shutter stays open longer to record the background scenery Many high-end digital cameras and digital SLRs also have an option to fire the flash on second curtain; in other words, just before the shutter closes This can add interesting effects to images and accentuate motion that occurs prior to the flash firing on the second curtain
