Nearly each one of us, who have digital pic camera, saw \'grainy\' pics at least once. Thats thanking to colored pixels (so-called grains, speckles) that are present on photos, but do not exist in the reality. \n

There are lots of causes why the noise happens to digital photos: long exposure times, heating of the camera sensor, high ISO settings, matrix defects, small pixel size etc. The effect is very frequent to the consumer digital cameras that are built on CCD or CMOS sensors. \n

Digital noise is very unpleasant artefact that spoils really good shots sometimes. Every shot corresponds to a very special moment which will never happen again, and the only thing we\'ve to do with a cool, but noisy pic is to retouch it slightly to make it perfect. \n

Does such a post-processiong software exist? Yes it does. There are lots of noise reduction photoshop pugins (for both windows and macOS) specially designed to remove noise grains from digital photographs: \n

The utilities grant reduction of (together and separately): luminance noise and color (chroma) noise. Additional options include fading, blurring and sharpening edges. \n

So, removing of the most unpleasant picture imperfection - the digital noise - is possible and much more easier than one can imagine. Due to modern image processing algorithms, the plugins can work almost automatically, so noise reduction does not require any advanced personal skills from a photographer. \n

Noise reduction is made easy nowadays.
