When you notice spots or fuzzy smudges at the same place in every frame you shoot (something you will particularly notice in images containing areas of clear sky), it means that dust and dirt have attached themselves to the surface of your camera's digital sensor. Cleaning the sensor is a delicate process and doing so incorrectly can do permanent damage. So leave your camera overnight and let us clean your sensor. We'll do it correctly and safely and we'll turn it around in just one business day. Our professional sensor cleaning is just $75.
