The main pane takes over three quarters of the window which means a smaller window and a less cluttered area. In terms of layout, the only real difference between Dfine and the other Nik programs is that there are no options on the left side of the screen.

Several markers will appear on the picture in the main frame in the centre which are the points that the program has read from. It takes a second to open and a further five seconds or so to analyse the picture for noise. The program only works when you have an image open in Photoshop and it is accessed by going to the Filter tab. Unpacking and installation is also fast and easy so you can get editing straight away. Useful noise such as acutance which appears to sharpen edges without actually increasing resolution.ĭfine is a relatively small program so downloading only took us a couple of minutes. There is some noise that can be useful and is called dither. They're caused by a number of situations such as a high resolution on a comparably small sensor, amplification of the sensor's reaction to light and even heat given from neighbouring pixels. There are several different types of noise that can affect your pictures such as salt & pepper, Gaussian (amplifier), uniform, film grain and non-isotropic noise. Nik Dfine 2 costs $99.95 / 99.95 Euros, or $69.95 / 69.95 Euros to upgrade from version one. As with those two products, Dfine works as a plug-in for your Photoshop, Lightroom or Aperture programs. There's also the same U Point technology that we saw in our reviews of HDR Efex Pro and Color Efex Pro software packages. Building on the initial version, new features include an improved noise reduction engine with automatic profiling, an improved user interface and if you're a Photoshop or Lightroom user, you can enjoy a powerful selective tool, smart filter compatibility and multi-image support.

Dfine 2.0 is the second edition of noise reduction software by Nik software.
