Photography in Dim Light
By Sam Zaydel
Most of us at one point in our photographic history
realized that capturing images in dim light, or fair
darkness changes an otherwise mundane scene into a much
more interesting, and in many cases a surreal scene. While
capturing this scene in normal daylight is typically fairly
straight forward, working with very low light is quite a
bit more difficult. There are many minor issues, and just
as many larger issues which make it tricky to capture good
photography in dim light. As such, we will discuss the big
issues which everyone without a doubt has encountered at
some point. Sharpness, and accuracy of exposure is always a
concern when the light is low. So, let's dig deeper into
these issues, and discuss suggestions to improve your
low-light photography.
If you are like most people you shoot your low-light, or
night photography on the go. This of course means that
unless you are already a pro, and have an assistant who
carries your tripod, you have to carry it yourself. In most
situations tripods are a great tool, however we may not
always have them available to us, and at times traveling
with one is not easy. There is nothing out there that will
replace a stability of a tripod, however if it were not an
option there are other things we could do to compensate for
low-light. The most simple way is to increase your camera's
sensitivity to light. It may sound weird to amateurs, but a
higher speed (higher ISO) film, or a setting on a digital
camera makes the instrument more sensitive to light.
Basically, the higher the ISO setting on your digital
camera (ex. 100, 200, 400, 800, 1600, etc.) or the ISO
rating on your film, the faster it will respond. There are
disadvantages to every advantage, and this is no exception.
Higher ISO setting on your digital camera means lower image
quality. While the camera does become more sensitive to
light, and is able to capture lower amounts of light to
“paint” the scene correctly, the high ISO also causes
“digital noise”which looks like grains of sand sprinkled
over the image. Luckily, technology is getting much better,
and there are now digital filters built right into the
camera which reduce this noise.
Nonetheless, there is some loss of quality. In fact, with
most Point-and-Shoot digital cameras the effect is greater
than on digital SLRs (Single Lens Reflex cameras), because
the image sensor, which actually captures the image through
the lens, is very small, in many cases the size of your
thumb nail. If you are planning to shoot a lot of low-light
photography, consider upgrading to a digital SLR, if you
are using a Point-and-Shoot, and are familiar with effects
of digital noise. If you are still shooting film, the same
problem exists, and higher ISO films are often much more
“grainy”than a photograph captured with a digital camera.
Some photographers introduce higher ISO films on purpose,
because grain is at times considered an artistic effect,
however, it has to be used wisely. If you invested in a
film or a digital SLR, your options are more open. If you
have a reasonable budget, consider getting a fast lens,
which will allow more light in and require less sacrificing
on the side of quality. Many new digital cameras come with
an “Image Stabilization”which allows for sharper images
captured at lower ISO settings without a tripod, or another
stabilizing device.
Just when you thought getting around without a tripod was
difficult enough, I throw another curve ball at you.
Overexposed Highlights – are common in photography captured
in low light. It is a fine balance, and you never win. You
either overexpose the bright light, or underexpose the dim
areas of the scene. There is not one solution to this. Try
to keep your exposures short, whether you use a fast lens
on your SLR, or a higher ISO setting on your
Point-and-Shoot, as this will reduce the overexposed
lights. If your camera allows for exposure bracketing, use
it, and it will help you get the right balance of light and
darkness in the scene. Stay away from using any sort of
flash, unless you are photographing people, and not a dimly
lit scene. If you are shooting people in a club, a pub, or
any other dimly lit place, use your flash, and try to be
fairly close to your subject(s), because flash drops off
very quickly. If you are shooting a street scene, a night
landscape, a harbor, or any similar scene, the mood of the
scene will be destroyed if any flash is used. The resulting
image will be underexposed, and only very near objects will
be captured.
Obtaining focus may be difficult at times, when the light
really drops off. This is when a manual focus comes in
handy. It is unfortunate that most Point-and-Shoot cameras
do not have a manual focus option. However, many new
cameras have pre-focus lights built into them. If you have
this option, make sure it is enabled. The camera sends very
quick bursts of light to light the scene, and allow it to
obtain focus. In extreme situations a flash light may help
too. Simply shine it in the direction of the lens, and let
your camera focus. Needless to say, when it is so dark, you
MUST have a tripod.
While you will certainly encounter other problems shooting
in dim light, the topics covered will no doubt ease your
photographic efforts. Ultimately, most of your success will
come from practice, and experience.
