Low Light Photography Options
When shooting with a subject in low light situations you generally have two options; either to shoot with a flash or to shoot with a slow shutter speed.
1. Flash – When shooting in low light with a flash in auto mode your camera will choose a relatively fast shutter speed. This means that your subject will be well lit and that if it is moving it will be frozen and as a result will be sharp. The problem with this is that it can also leave your subject lit up too brightly and can leave it’s background looking very dark as there is not enough time for the camera to collect any ambient light.
2. Slow Shutter Speed – The other option is to turn your flash off and shoot with a longer shutter speed in order to collect enough available light from the image to get a well exposed shot. This can be an effective technique if you’re shooting landscape or environmental shots where everything is nice and still – however if you’re shooting a moving subject it means you’ll get motion blur which could ruin your shot.
Both of the above options are legitimate technique but both have their weaknesses. Another options to consider is slow sync flash.

Slow Sync Flash is a function found on many cameras that tells your camera to shoot with both a longer shutter speed as well as firing the flash. This means you get the best of both worlds above and can both get a relatively sharp shot of your main subject as well as get some ambient light from the background and foreground.
