    dust on your sensor
    need to clean the sensor to get rid of them
    Great photography is about depth of feeling, not depth of field.

    dust can also get inside your lens. to check if it's the lens or sensor, take a picture of a white piece of paper or wall... and then switch lenses and repeat. if the spot is in the same place it's the sensor.

    Confirmed sensor...

    coz your shot was at f22.... try it again at large apertures, you shouldn't see it.

    Go for a sensor cleaning session.

    Thank you.

    Do you have any article or website to demonstrate how to clean sensor?

    Anyway, it is time to learn how to clean sensor by myself...
    as dust will always surrounding us for life time, it is better we learn how to clean it.

    it can be done. but be gentle and do not apply excessive air pressure to remove the dust from the sensor, let alone say touching the sensor.

    Forget it, how often do you shoot at f22. At f5.6 you are unlikely to see the spot anyway. After cleaning, how long does your sensor remain clean ? (till the next time you change lens ?)

    Not sure which camera you are using... but why not just send it down to the service center for cleaning? If the camera is under warranty, sensor cleaning is free.

    You don't have to clean the sensor regularly if its not affecting your pictures too much. An obvious speck here and there can be gotten rid of by cloning in PS.
