“The Compleat Angler” – This hotel, pictured from Marlow Bridge, Buckinghamshire UK generates a surprising amount of light. Click image to view large.

Shooting by moonlight or other dim lights

It’s true. You can shoot in almost total dark with a digital camera. You make exposures of many minutes and use really dim lights – the moon, stars and low-level hand-held lights are enough for the camera to pick up.

In other articles about night photography we looked at Planning and Preparing for a Night Shoot and Out on a Night Shoot – Night Composition. We also looked at Six things you must know for night shoots including the basics of controlling the camera and the sort of settings used. It is worth following up on these articles before proceeding.

Night light

Out of town, away from the urban lights, dark is really dark! Many urban dwellers don’t realise that unless the moon and stars are out our eyes are pretty poor in complete dark. Yet, when the moon is out, and the stars, we can see pretty well. In fact our eyes are not well adapted to this darkness. However, the digital camera can pick up amazingly small amounts of light. In the photograph above the EXIF data is…

Ten seconds is a reasonable time with all that light knocking around. Remember that an exposure is like filling a bucket with water. As light enters the camera it fills the exposure, making it brighter and brighter as the shutter is open longer. So, in very low light situations you can take photos with very long exposures.

One thing to consider is how to set the length of exposure. Most cameras cannot time your exposure if it is going to be longer than thirty seconds. You can buy automatic ‘intervalometers’ – devices which count intervals of time. They will be able to set your camera off for longer exposures than thirty seconds. However, on the camera there is normally a setting called ‘bulb‘. This will allow you to time a period yourself and close the camera shutter when you are ready. You can find out more about the bulb setting (B setting) in: What is the ‘Bulb’ Setting?

The video

In the following video, Mark Wallace takes us through the process of taking a photograph by moonlight. He is using a two minute exposure. Besides nearly getting eaten by coyotes (OK I exaggerate) he gets some well lit shots. Remember he is out in the country where there are no lights and is just using the ambient moon/star light.
