Working With Low Light

Photography Lighting: how to master shooting in low light


From dimly lit interiors to shooting outdoors before sunrise or after sunset, shooting in low light presents very different challenges to shooting in bright conditions.
It’s often difficult to get the right exposure using the automatic modes in dark conditions, so you’ll need to master Manual mode.
These conditions can also make things like focusing and white balance more challenging, but it’s worth overcoming them, because shooting in low light can result in stunning images.

Exposing in low light

Shooting in darker conditions can play havoc with your camera’s exposure settings, especially if you’re using any of the automatic exposure modes, because the subject will rarely contain a normal range of tones.
In most low-light situations you will get much better, and more predictable, results by switching to Manual.
If the subject contains mainly dark tones you’ll find that your camera will over-expose your shots. This is easily visible, as there will be too much detail in the shadow areas.
The best way to assess the exposure is to take a test shot, and then check the histogram graph. If there’s a gap to the left, the image is over-exposed so you need to use a faster shutter speed, smaller aperture or lower ISO.
When it comes to choosing the exposure settings for shooting in low light you have some decisions to make.
Firstly, do you need to use a fast shutter speed to freeze movement or prevent camera shake if you are handholding the camera, or are you happy to put the camera on a tripod and use long shutter speeds?
To use a fast shutter speed in low light you’ll have to use a high ISO setting, such as 800 or above. But when using a tripod you should set a lower ISO such as 200 or lower for the best quality.
