What is Digital Camera Noise?

Digital Camera Noise is a bunch of color speckles instead of continuous color. It is illustrated on the photos below. The photo on the left is an original digital photo with lots of noise. The photo on the right was modified with Paint Shop Pro 9 digital noise reduction feature.


Digital camera noise usually is produced at low shutter speeds and high ISO settings which are used in low light conditions. Besides Paint Shop Pro 9, there are other software programs that can be used for digital camera noise reduction. One of them is Neat Image which is also available for the Mac.
