Image Noise

Tips to avoid image noise

  • Decrease ISO rate
  • Activate noise suppression on camera (Disadvantages: only works for longer exposure times, can prolong post-processing, loss of image details)
  • Use software to reduce image noise e.g. Neat Image

Image noise is always connected to the ISO setting. This connection is explained in more detail in the article “Connection between ISO rate and image quality”.

The following images illustrate the connection between image quality, ISO rate and sensor size.
