Noise Reduction

RAW image noise should be reduced as soon as possible in the workflow (i.e., using your RAW converter) before it can be intensified by other correction steps. Although the quality of noise reduction offered by Photoshop plug-ins such as Noise Ninja [80] or Dfine [75] is better than that provided by most RAW converters, performing slight noise reduction early on in the workflow still helps to produce better overall results.

Some noise reduction algorithms are based on ISO and camera model EXIF data. Bibble has Noise Ninja's excellent noise reduction functionality built in. The quality of the noise reduction tools built into RAW converters is improving rapidly.

Reducing image noise usually reduces overall image sharpness (to some extent), resulting in close interaction between sharpening and noise reduction processes.
