Nik Software HDR Efex Pro NIK-1406 User Guide

Dfine 2.0 contains a considerable amount of enhancements and 
improvements from Dfine 1.0. The majority of the improvements can 
be summed up in 4 categories:

- Interface

- Noise Reduction Engine

- Noise Reduction Process

- Selective Tool Interaction

One of the most obvious new features of Dfine 2.0 is the completely 
reworked interface. The interface represents the culmination of 
extensive study of the look and feel that professional photographers 
expect in a modern application along with requests from Nik 
Software users.

The new interface was designed to look and act as a professional 
photographic tool, with a color-neutral interface, medium-gray 
background, and a strong focus on an efficient workflow.

Dfine 2.0 is completely resizable and groups important controls next 
to one another, leading to less mouse clicks and therefore greater 
efficiency and less time needed to achieve excellent quality noise 
reduction results.

Please see 

 for more information on 

the various tools and features found within the Dfine 2.0 interface.

Dfine 2.0 contains a completely reworked noise reduction engine. 
The goal when creating this new noise reduction engine was to 
empower photographers with an incredibly powerful and precise 
tool to reduce unwanted artifacts within photographs with the ability 
to maintain high levels of detail, all without requiring a complicated 
process or learning curve.

Dfine 2.0 
Noise Reduction 
Engine

Dfine 2.0 incorporates an advanced, unique wavelet algorithm, 
specially designed for use on photographic details. To support the 
noise reduction algorithms and to ensure as simple and straight-
forward a workflow as possible, an automatic profiling system was 
also developed.

The automatic profiling system was designed to make noise 
reduction as easy as possible while working on the broadest range 
of images as possible. A lot of care and attention was taken with 
the automatic profiling system so that it would provide an optimal 
profiling result for the majority of images, with no input required.
