White Balance and Night Photography


Auto White Balance
Camera is not able to automatically correct for the 
mercury or sodium vapor street lighting
Tungsten White Balance
Tungsten White Balance has a different color characteristic compared to mercury
or sodium vapor lights. The color correction is not accurate.
Custom White Balance
When shooting snow or other neutral subject matter, it is easy to get a custom white balance at the time one shoots the photograph. If there is not a readily available neutral or white target to use for custom white balancing, consider shooting in RAW and using the custom white balance tool in your Editing program. Customizing while editing is a good tactic when there are mixed light sources or when you want flexibility in deciding the perfect color balance.
