"Image noise" or "digital noise" is a common problem. When you click photos in low light conditions or not with a great camera, image clarity suffers. The image is suffused with tiny dots making it look grainy and distorted. Noise is actually the disturbance of pixels due to which the colors of pictures are not depicted properly.
Shoot at lower ISO settings: ISO settings in your camera decides the noise level in your photos. Generally, higher ISO settings cause more noise in your images. Different cameras work well at different ISO settings though keeping ISO level low is advisable. Shooting at lower ISO means there will be less noise in your image. Higher ISO settings translated as a grouping of pixels together to capture more light. Hence this grouping effect can create more noise in your image. To avoid this, you can open your aperture to its widest settings or if you are shooting in a low light then you can use a tripod or a flash. Using “Auto ISO” feature should be your preference as then the camera itself decides the right level of ISO settings as per the light and other conditions like shutter speed etc. - articlecube.com
