I have just realised that there is some artifacts in my pics. I have only just noticed them and they didnt appear in my last set of pics from the same , i just checked. So obviously it it sitting on the sensor. I am very careful when changing a and dont do it very often and when i do i point the camera housing down and quickly change the . I have tried using the in camera sensor clean on my D7000 but it doesnt seem to do anything to remove the dust. I have set it to automatically do it after every shutdown of the camera. Is the in camera sensor clean different to what you would get when you take it to a shop to get this done by someone. And while im here where is a good place in the Eastern Suburbs to get this cleaned?
Here is the pic I just took of the sky to show up the little "£$%^*%!!!!
