Picture with photo bellow.
Photo noise is the appearance of coloured dots in parts of a picture where they shouldn't be. Flourishing and chestnut dots may incorporate the background, or a human race's face may develop hazy and gritty. Once referred to as "grain", photo bang occurs yet with the chief digital camera. Avoid long exposure times when possible. Change your angle or add light to reduce the exposure time needed. Use a tripod when you have to use long exposures.
Buy a digital SLR camera with a large image sensor. The larger the image sensor, the less noise you'll get in your pictures.
