There are so many options for noise reduction that full control of an image is possible. The Lessons go into details on many of the major features of the program and can be found in different formats such as video, Pod, and PDF. A very detailed description can be found under Lessons on the Nik Software website. The other Dfine 2.0 options will be explained later in the review.įirst, let's look at the particulars of the interface. To access the Dfine 2.0 screen, click on the word Dfine 2.0. You can set up the parameters so it will open whenever you open Photoshop. If desired, these plug-ins have the ability to be used as Smart Filters.ĭepending on how many of the plug-ins are installed, this box will vary. This will be discussed in detail later in the review. These settings are not global but similar to creating a selective area with a lasso tool. In Dfine 2.0 you can set up areas that will be affected by the noise settings you choose. Control Points affect an area that you establish. One of the basic feature is U Point® Technology which relies on Control Points. I will be treating each of my reviews on Nik Software plug-ins individually so there probably will be some repetition of features. This lessens the learning curve a lot although it doesn't eliminate it when using the different programs. Nik plug-ins share a basic uniformity of interface and type of controls. What causes this noise? In digital cameras high ISO speeds or very low light levels will produce noise so will severely underexposed images. Chroma noise shows up as blotchy discolored areas or speckles of unwanted colors.

When reduced it can lead to blurry details. Luminance noise looks similar to film grain. There are two types of noise: luminance (contrast noise) and chroma (color noise). Digital cameras generate noise as do scanners because of the CCD. To understand how a noise reduction program works, it is important to understand noise. Dfine 2.0 is a noise reduction application that is geared toward digital photographers.
