Using the Reduce Noise Filter in Photoshop

Sometimes, particularly when taking a photograph at a high ISO, the image can become “grainy” or “noisy.” Noise is an unwanted random texture in the image. In film, graininess is the result of using film stocks which contain larger, more sensitive, clumps of silver: hence the grainy appearance. In a digital camera, noise is the result of signal amplification: raising the ISO causes the the processor to multiply the output of your image sensor, multiplying the underlying electronic signal noise in the sensor and the camera’s circuitry in the process. Noise can add to a photo, but often it’s a pain and we’d like to get rid of it. Adobe Photoshop comes with a tool called ‘Reduce Noise’. In this tutorial, we’ll look at this particular filter and its effectiveness.
