Noise is a very important issue in digital photography. Nearly all digital cameras produce images with an easily noticed noise component. This 'digital noise' is especially strong in images taken at high ISO rates. Scans of negatives show a similar film grain. When the picture is taken in low-light (indoor/night) or high-speed (sport/action) the noise is even more noticeable and a tool such as AutoDeNoise is needed. The noise and grain reduce the visual quality of digital images and resulting prints.
NOISE SENSITIVITY
Digital image sensors, because of the size and sensitivity, produce a slight noise as photons arrive at random intervals. The induced sampling error produces the noise. Small sensors on compact digital cameras generate more noise but even top-of-the-line cameras at high ISO settings show some noise.
ADVANCED ALGORITHMS
Edit DeNoise uses a sophisticated algorithm that preserves detail and sharpness while removing grain or noise. Since noise are highly dependant upon the sensor of your own camera (even within same digital camera model, you will not get exact same result) and the picture you are taking, it is very important to rely on a fast and simple tool that offers to save the unique setting adapted to your particular camera and the kind of image you want to produce.
