Photography is all about capturing light – and what better way to document it’s presence than in a night time long exposure!

What you need


  • A steady hand – so get yourself a tripod!

  • Probably a remote because most cameras won’t expose for longer than 30 seconds using bulb mode.

What you want to capture
Drama, movement, contrast. Think:


  • Star trails in the sky

  • Car lights on a highway

  • An illuminated train speeding along a railway track

  • The spinning lights of a fairground

  • A scene lit by a full moon

  • Reflections of light in water

  • Light Painting with a torch

ISO, Shutter Speed and Aperture


Successful night time long exposures require a delicate compromise between ISO aperture and shutter speed. We have covered understanding ISO settings before (link to http://365project.org/blog/understanding-your-cameras-iso-setting) but as a quick recap:

ISO
A low ISO means that you can have the shutter open for longer because the film or sensor is less sensitive to light.
BUT
The graininess associated with high ISO is more noticeable on larger and darker areas.

Shutter Speed
A slower shutter speed means that you can capture more light and movement.
BUT
A slow shutter speed can also overexpose the darker areas - however this can create some amazing effects giving night time pictures an eerie daylight aesthetic.


Top Tip
To help achieve a sharper image at night use autofocus to focus on a point of light and then switch it off when taking the photo; or use a flashlight to illuminate up the area while focussing.

Aperture
For a less ‘grainy’ image you will need a low ISO, and to get more of the picture in focus, a smaller aperture.
BUT
Be careful, because the smaller the aperture, the longer your shutter speed and exposure will need to be to get the same image!

Top Tip? Experiment!


Start with an ISO of 100, a shutter speed of 1/60 and an aperture of F/2.8. With this you can expect to capture the blurred lights of a moving object.

Then adjust one element at a time to see how the image changes. First the ISO. Reset. Change the aperture. Back to the beginning, then find out what happens when you change the shutter speed instead.

Something like a star trail can require an exposure for at least a couple of hours, so when experimenting with exposure, keep an open mind!


Top Tip
Ditch the tripod (gasp!) and move your camera to create crazy light paintings without a moving light source.

Yes, there is more to night time long exposures than just capturing what is out there – create your own images through light painting. This can be achieved by ‘painting’ with a torch or other incandescent object (more of this to come in later post) in front of the camera or by moving your camera to create the movement.

cool... ta for using my shot :-)

Good tips too - But as someone who has only used a tripod a couple of times... flat surfaces are a god-send ...:-)

Even if you think you got the settings right, keep experimenting because what looks good on the lcd, may not once you get back home

This is a shot that I took last year, of a flight coming into land at Kos Island airport. Very simple, yet rather original.

This was a long (4 second) exposure in a supermarket car park with my camera sitting on top on my car.

I love night time photography and have posted several in my album. My favourite one is one I took last year in the golden hour (before I'd found 365) and posted recently:

I love taking long exposure shots. Here's one of my first attempts at light painting.
