Very often, when I go to do tours, I am asked to take stills as well. I have always use the Canon G6 with the Canon wide angle converter. The shots have always come out great. I have no idea what has happened. I use it on bracketing and then combine through Photomatix. Can any one tell me why my shots are now so grainy? Is there something wrong with the camera? I do not believe that I have changed any of my settings. Can someone give me an idea where to start looking for the problem?
