Low Light and Night Photography

Low Light and Tripod ...

As the names suggests we are trying to capture a scene or a subject under very little ambient light.

This brings the needs to leave the Shutter open for a longer time ,than we would, under normal lighting conditions to give the Sensor enough time to take in the subject with the available light...

Now.. that introduces another equipment... the Tripod... because we normally cannot have the camera hand held ... and be able to hold it steady for a long time as well ..

ISO can be kicked up to a higher value to increase the sensitivity of the sensor

Note : Longer Shutter speeds would need you decrease the F Stop (e.g 30 Seconds....and F8 in the example below.. My cam doesn;t go beyond that )

The Example here.. was shot with Shutter Priority ... meaning... i only had to set the Shutter Value to 30 Seconds... the Aperture(F) and the Exposure (0/10) were automated..

This shot was taken with the camera mounted on a tripod looking out the window and with shutter open for 30 seconds.

i've pasted the EXIF info below ...

Camera : Sony DSC H5 set to Shutter PriorityExposure: 30 sec (30)Aperture: f/8Focal Length: 6 mmExposure Bias: 0/10 EVFlash: Flash did not fireAs 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.


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.
