When shooting with a digital camera, image noise (image roughness or 
unevenness) becomes noticeable in the following situations.

- when shooting with a long exposure
- when shooting with a high sensitivity setting
- when the temperature of the CMOS sensor is high

You can reduce image noise by using Noise Reduction. However, images 
shot with Noise Reduction will take longer to save.
