07 Employ a graduate
With most seascapes, your shots will also benefit from using a second filter – a graduated ND filter that darkens the sky in the top half of the shot and lightens the foreground. A two-stop (0.6) soft-edged graduate is a good all-round choice that will do wonders for most landscape shots.
08 Minimise vibrations
With such long shutter speeds, you’ll need to use a cable release and Live View to avoid shaky shots caused by the camera’s mirror moving as it takes the picture. The combination of long exposures and Live View means your battery won’t last long, so make sure you have a spare (find out what Live View is telling you).
09 Salty spots
Salt spray on the front of the lens is an occupational hazard, and if you don’t check for it, it can leave marks on your pictures that can be hard to clone out. Make sure you have a lens cloth at the ready – and a towel, just in case there’s a bigger wave that catches you unawares!
