Adjusting the levels, spot healing.

After setting the resolution 300 dpi the next stage that I do is to go into the levels.  I don't always do this as I am sometimes happy with the shots at this stage, but this gives me an option to twick the shots if required.

This is the work flow that I sometimes use.  But normally after the first stage opening in Raw and doing Auto.  The shots are good enough at that stage.  There are sometimes, that I have to spot heal as with changing the lens outside the images have little spots on them which means that there are dust particles on the censor.  Below is what I do to help not have spots on the shots.
