The right half of the picture shows color noise, a confetti torrent of single or multicolored dots. It is richly nourished by incorrectly executed sharpening, which can turn a weak graininess into a raging ash-storm. It can be observed in the form of monochrome grains that can decrease the sharpness of the picture to a significant extent. The left side of the picture below shows luminance noise, emphasized by sharpening. As you can see, they deal with the two most important noise types, color and luminance noise. Speaking of sliders, Luminance Channel specifies the noise level for the luminance channel, while Chrominance Channel does the same for the color channel(s). Leave these sliders at 0% for now, you’ll still have the possibility to adjust them later. Negative values indicate a lower noise level, while positive values a higher one. That is, if you set both sliders to 0%, you specify a noise level exactly identical to the one in the profile. You can set the noise level relative to the predefined profile in the Noise Levels region. Make sure to zoom the photo to at least 100% before using the preview as it is needed to see noise and how well the removal works.Īpply executes the noise removal on the whole picture, using the current settings.īut let’s return to the sliders for now as the settings are not yet complete. You can also drag a selection rectangle in the picture. Simply click the button to have the application select an area (the middle of the image). Preview shows the effect of the current noise filter settings on a selected part of the picture. The Preview and Apply buttons in the upper left corner are also important. These reset the controls to their default values. There are two Trash icons above the sliders. The first is for loading previously saved settings, and the second for saving the current ones. Above them, there are two icons again, this time in purple instead of blue. Most of the options can be specified using the sliders on the right. The next component can be invoked by clicking Noise Filter Settings. This way, you won’t need to prepare profiles for those images, you can simply open the saved one instead. If you have taken more photographs with the same camera and in similar circumstances that also need noise filtering, save the profile by clicking Profile/Save As. After successfully drawing the box, click Auto Profile. If you fail to do so, a warning message appears. You need to specify a homogeneous area of at least 64×64 pixels by dragging. Click the button to have the application look for a homogeneous area in the picture, and set up the noise profile based on it. The fastest of the mentioned options is Auto Profile. You can download profiles free of charge for numerous brands and models from the developer’s website. Click Profile/Open, or the first icon above the device info region in the upper right area. You can also open a pre-defined noise profile for your camera. Both relevant buttons are in the upper left corner of the window. You can open a test image done with an identical camera and film speed/sensitivity ( Open Test Image), or apply the plugin’s Auto Profile feature to a homogeneous area in the current photo. There are two easy ways to produce a noise profile. The other component, Noise Filter Settings, does the actual filtering and lets you specify the relevant settings. Simply put, it produces a map of noise layout and extent. Device Noise Profile attempts to assess the profile for the camera used and the photo’s noise level. Neat Image basically consists of two main components, activated by clicking the tabs under the menu bar. Click Tools/Standard Mode to switch to the simplified interface. The application window looks just the same as in the stand-alone version. You’ll have to load a photo first, of course. Despite this statement, we still introduce the plugin now with its simplified user interface.Īfter installation, click Filter/Neat Image/Reduce Noise in Photoshop. Albeit Photoshop‘s newer versions already contain a noise filtering feature, Neat Image and similar dedicated tools offer more settings, and likely a better and more accurate result. One of the most well known such applications is Neat Image, also available as a plugin for Photoshop (and other widely used photo editing programs). Fortunately, anyone can find suitable noise filtering software, if the relevant features of their camera won’t do the job all right. Nowadays, self-assured digital photographers don’t fear a bit of image noise.
