Night Photography – 30secs or longer
Shooting long exposures can also result in hot (or stuck) pixels. These are individual pixels that appear much brighter than those around them due to their response to light.
Using the long-exposure noise reduction feature helps to reduce the visibility of these in your image, but you can also remove them using the Healing Brush in Photoshop.
Suggested shutter speeds for night exposures
- Movement just visible in stars, or full moon-lit landscapes: 2 minutes
- Distinct star trails: 10 minutes
What you can do
When shooting night photography it’s common for shots to have much more noticeable noise than normal. To minimise this problem most cameras have a long-exposure noise reduction feature, which can be activated via the main menu.
But there are times when you shouldn’t use it (for more on shooting at night, check out the 12 common errors of night photography – and how to fix them).
