Neat Image is a small program designed to eliminate digital noise from photographs and enhance overall image quality. It is offered as a standalone application compatible with Windows, Mac and Linux platforms, as well as a plugin for Adobe Photoshop on both Windows and Mac.

WavePurity is designed to assist users in editing audio files and eliminating noise from older recordings, developed by DIFITEC from Germany. It allows users to remove noise, clicks, crackles, and other imperfections from their audio files, resulting in a cleaner and more professional sound. It also offers features for restoring old recordings, such as vinyl records or cassette tapes, by reducing hiss and enhancing the overall audio quality.

Noise is most commonly seen in photos taken under high ISO or low light conditions (such as fast action shots, shot at night), but also common in a variety of image files with lossy compression. In cased like this, a good noise-cancelling application becomes an essential tool in every photographer's toolbox.

Digital Camera Enhance (DCEnhance/DCEnhancer for short, AKA: Free Digital Camera Enhancer) is a free and tiny image processing automation program developed by MediaChance (written by R. Voska) from Canada. It's mainly used to manually or automatically bring blurry photos taken with a digital camera into focus with one click! Therefore, it is very suitable for processing photos taken when the light is not good enough (indoor, with shadow, etc.), and especially good at making cool portraits and close-ups.
