Hope this might be helpfull. I think they are worth knowing (if you don't already of course) ...
ND Grad will bring the exposure of the sky closer to the water/sand so it doesn't overexpose and 'blow out'.
Polarizer Filter will increase the colour saturation significantly.
UV great for reducing the haze.
In B&W, to increase the contrast on v cloudy days red (more) or orange (less) filter, yellow to reduce it (bright sunny days).
81B or C to 'warm up' the colour and take out the blue cast that can appear be captured on film on clear sunny days.
Those Ebony snorkels are great too!!! and mustn't forget the UV filter lotion :rolleyes:Originally Posted by lee
