Image Processing Technique: Noise Reduction

Learned a new technique today, which is the following:

  • Noise reduction on Lightroom. By zooming 100% – we can adjust the noise reduction but at the same time avoid the image from being washed out.
  • Masking the sharpening. By pressing the key Alt (Option) while adjust the slider, we can see the areas where the photo will be sharpened. More importantly is that the noise that was introduced by the camera are not sharpened. If this gets sharpened – the noise will be come more apparent. As such – we need to pay around with this.

Not sure if the photo below do any justice. The difference can perhaps be seen if I were to print this.
