The best way of dealing with noise is prevention of its emergence. Noise in images arise in poor light conditions under which the camera or the photographer much have to raise the ISO value. Already at ISO to 400, the photos there are strange artifacts, but if the ISO is raised to 800 or even 1600, the noise in the photo you can not avoid. Blurred gaudy stains can greatly affect the quality of the image, remove them as special filters and tools which are integrated in the editor Photoshop.
