and i ask my kakis about the filters...they tell me got a lot of
kind..
the more i hear, the more confused i get..
i only have normal UV vilter.
install photoshop
shoot raw and bracket ur shots to get 3 exposures
go back home, use photoshop, u will have more fun and create
miracles. 
i enjoy playing with photoshop more than shooting. i can spend
1/2hr shooting but hours on photoshop
