Flash Photography - How to Avoid 5 Common Problems
Whether the flash on your camera is built-in or a separate unit,
you use it to provide enough light on your subject to take a
good photograph. When just starting out taking pictures with
your camera, you will undoubtedly encounter at least one of
these problems when using your flash. This article provides you
with at least one solution to each of these common problems.
1. Flash Glare behind subject - this is usually the result of
taking a photo of your subject with a reflective surface, such
as a mirror, window or polished surface, behind the subject. If
it is not possible to move your subject, take the photo at an
angle to the reflective surface so that the light from the flash
does not reflect directly back at the camera.
2. Subject too far away - you must know the range of your flash
to know just how far the light will effectively reach. On
average, the maximum distance is about 15 feet. If your subject
is any further away the photo will be dark. Also note that there
is a minimum distance as well, usually about 2 feet. This
explains why the photo you took at the concert had the head of
the person in front of you over-exposed and the stage in
relative darkness.
3. Red-eye - the light from the flash reflects off the retina in
the eyes of your subject causing them to appear red in the
photo. Many cameras have a red-eye reduction feature that fires
the flash once to make the pupils of the eyes close more and
then fires again when the photo is taken a second later. If you
do not have this feature or don't wish to use it, simply have
your subject look slightly away from the camera.
4. Glare on Glasses - if your subject wears glasses and prefers
to leave them on, you can effectively eliminate the glare by
having them tilt their glasses down slightly.
5. Shadows - if your subject is standing close to a wall, the
flash may cause a dark shadow to appear as a halo around your
subject. If possible, have your subject move away from the wall.
If this is not possible and you can adjust the angle of the
flash, bounce the flash off a reflective surface - a light
colored wall or ceiling will do. The light from the flash is
more diffuse and will reduce or eliminate the dark halo.
