This is characteristically dust on the CMOS sensor, particularly apparent at small apertures. > What do I clean and how? Oh yes it�s a Canon D10. You need to clean the CMOS sensor. There are a couple of options, the first is to get it done professionally by either sending it to Canon or somewhere like Fixation. Only problem is that you will have to wait a couple of weeks or longer before you get the camera back. The second option is to clean the sensor yourself. It's not difficult to do provided you know what to do and are clear in your mind. Here is a good link that will provide some useful information and several other links that will help you even more: http://www.ultimateslr.com/clean-image-sensor.html I think you can also buy kits on the market for sensor cleaning, I've never used any myself so cannot say how good or bad they are.
