Low Light and
Night Photography
Author

As the light
fades, do thoughts of photography wane also?
If that's the way you think then read on as
we will be showing you that low light
photography is awash with opportunities!
Images, whether from film or digital
cameras, need one ingredient... light. How
then can photographers get good images in
low light conditions? Using flash would be
one way. But even the most dimly lit scene
has some light - and that means the
potential for a great photo!
What equipment will I need?
Well, you will need a camera as well as
charged batteries, that's for sure. Also, a
tripod is invaluable for exposures lasting
greater than 1/30th second (1/60th in some
cases). A torch, a decent lens and think
about a remote shutter release - using long
shutter speeds means the potential for
camera shake and blurred images is even
greater than usual (the alternative is to
use a self timing mechanism to trip the
shutter).
What about white balance?
Night time often means scenes lit with
artificial light. This will inevitably give
a colour cast to your shots although this
can be pleasing sometimes. There are many
types of lighting (tungsten, halogen,
fluorescent) and they will all come out with
different colour casts - live with it! Try
different white balance settings to see what
effect it has on the final image.
How do I calculate the exposure?
This can be difficult. But with modern
digital cameras you can see the results
immediately and therefore make any
adjustments straight away. Your meter may
lie! Be ready to change the settings (and
give a longer exposure). Night time shots
can be very contrasty (bright lights and
deep shadows) - the camera won't be able to
cope with the extremities of exposure so
just change the settings yourself until you
are happy with the results! You may need to
use the "B" or "Bulb" setting to hold your
shutter open for long periods.
What can I photograph at night?
Virtually anything! The choices are almost
limitless. We suggest you consider:
Buildings
Lights
Signs
Bridges
Cars / vehicles
Lit houses / pubs / shops
People (motion blur can be a useful effect)
Street illuminations
Fireworks
Bonfires
Fairgrounds
Reflections in lakes, pools
Look around for other ideas. Don't forget if
there is any light at all, it can be turned
into an image.
To calculate exposures you can use a rule of
thumb - see below for rough examples of
exposure times. However, each circumstance
will require a different approach so you can
expect to adjust things frequently!
Night (assume f16 ISO 100)
Town / City 20 sec
Signs / Lights 2 secs
Streets 20 secs
Streets 20 secs
Churches 30 sec
Fairgrounds 10 - 15 secs
Candlelight 60 secs
Fireworks 1 - 60 secs
One
interesting aspect of night photography is
the recording of moving trails of light.
Cars, buses, trains, bikes will have bright
headlights and tail lights which will record
as trails across your image if you shoot
them whilst they are moving with a slow
shutter speed of anything from 2 - 20
seconds. Try it! The same goes for
fairground rides. And don't forget that you
can create your own trails with statically
lit objects by zooming in or our during a
long exposure or even panning the tripod
head.
Bracketing
By taking a shot of a scene with, say, as
stop of under exposure and a stop of over
exposure, you will be more likely to capture
an image that is correctly exposed. Bright
lights tells the camera to underexpose. Many
cameras will have automatic exposure
bracketing to allow this to be done with
minimal fuss! You are trying to record some
detail in the shadows without burning out
the highlights. If you take an image of a
scene at 4 second exposure, take the same
scene with 8 seconds and 2 seconds. In this
way you will be likely to get the exposure
you are looking for.
Night photography “feels” different.
Different sights, different sounds,
different locations and different camera
settings. Nobody is an expert – we all have
to experiment. With modern digital cameras
this is something that can easily be
achieved.
Have fun!
