You can save and reuse noise profiles and filter settings. You can manually select the desired noise profile, rely on default filter settings, or manually adjust the noise filters. Profile Matcher automatically selects the best matching noise profile based on the input image’s EXIF data. It lets you build noise profiles automatically or manually: Auto Profiler is the easiest and quickest one-click way to build a noise profile, or you can manually select an image area for analysis and let Neat Image do the rest. Neat Image builds and uses device profiles from any image-acquisition device (camera or scanner). Neat Image ( is available as a stand-alone application or plug-in and uses noise reduction algorithms the company claims “surpass the quality of classic noise reduction methods and even that of the wavelet-based methods” and I am impressed enough by the results to make it my go-to choice for noise reduction. They also offer a profiling chart that lets you build your own profiles. To refine its noise reduction capabilities, it uses camera profiles that are offered free on its website. Noise Ninja uses a proprietary type of wavelet analysis that avoids introducing artifacts, such as fringing or blurring edges, to the final image file. PictureCode’s Noise Ninja is available either as a stand-alone application or Photoshop-compatible plug-in. PictureCode recommends that photographers use Noise Ninja even if an image was shot at a low ISO setting because they claim you’ll be able to make larger enlargements before noise becomes a problem. It includes a set of tools for automatic and manual noise analysis and a “Noise Brush” that lets you undo or redo the effects of noise removal in luminance, chroma, or color channels. (The stand-alone version only costs $10 more.) Noise Ninja uses a proprietary type of wavelet analysis that avoids introducing artifacts that can cause blurred edges. The $69.95 Professional version works with 16-bit TIFF files (48 bits per pixel) and supports batch processing and multiprocessor computers. PictureCode’s ( Noise Ninja runs on both Windows and Mac OS X and is available as a stand-alone application or plug-in. Both versions use heuristic programming that continuously perfects processing so every time you process an image, Noiseware learns more about your camera or acquisition device. Imagenomic’s Noiseware Professional is available for Mac OS and Windows as a plug-in or stand-alone product. Both use heuristic programming that continuously perfects processing so every time you process an image, Noiseware learns more about your camera or scanner. Noiseware is available for Mac OS and Windows as a plug-in or stand-alone product in both Standard ($49.95) and Professional ($69.95) versions with the biggest difference being 16-bit capability in the Pro version. The plug-in allows the detected noise levels to be adjusted by tonal and color range while it preserves image detail based on tonality range, all the while processing to guard against excessive changes. Noiseware’s self-learning mechanism automatically calibrates a noise profile and chooses the optimal noise removal settings without requiring camera-specific profiles. The interface is intuitive and you’ll get excellent results without having to read the Help file. Imagenomic’s ( Noiseware removes high and low ISO noise and JPEG compression artifacts from digital files as well as grain from scanned film.
