Noise reduction’s effectiveness varies depending on where it
is applied within the image editing workflow. Noise is a subtle
variation of recorded light values from one pixel to the next. The
more enhancements you apply to an image before reducing noise,
the greater the variation. As this variation increases, noise reduction
applications become less able to reduce unwanted artifacts without
degrading image detail.

Turning off these functions ensures that image details are preserved
and enables Dfine 2.0 to provide precise and powerful noise
reduction. Additionally, turning off sharpening functions in your
camera or RAW conversion application prevents amplification of
noise structures in images. If you choose to apply RAW or capture
sharpening to your image, do so after using Dfine 2.0, ideally with
Nik Sharpener Pro 3.0.

Apply noise reduction only when necessary.
Because noise reduction alters detail structures, however subtly,
apply noise reduction only when necessary. All images contain
some noise, but noise reduction should be applied only when noise
detracts from an image’s subject.

Typical situations in which noise reduction is indicated are:
• When using high ISO settings on your camera
• After accidentally underexposing a series of images
• When opening up shadow details in an image
• Whenever noise is visible in an image
Dfine 2.0’s workflow is straightforward: measure noise, then reduce
it. The interface walks you through and automates the process
of measuring noise and provides the tools you need to reduce it.
