Taking my F80 on holiday to Naples. Hope to do a lot of shooting around Pompeii in July. I'm guessing there will be lots of light around.

I was thinking about buying a filter as the intese light may cause problems, but I'm not sure if an ND grad or polarising filter would be better. Some books suggest that the circular polariser can do the same job as an ND grad.

Does anyone have any thoughts/recommendations?
