Excuse me if I laugh...and the laugh is on me... This is just about where I have a spot inside the camera that needs looking into! Maybe I'll tell people it's a pollinator!
@Weezilou Hi Louise - I think you are probably right about the spot! I've since seen it in a few other photos too. Do you have any suggestions about how to remove it - I've only ever owned a pocket camera so have no idea of the process. Cheers Rob
