Paradise sunset: vivid colors in a rocky stretch of coast, Sardinia, Italy

Paradise sunset. The warm light of the setting sun has painted the running clouds with vivid colors, balancing the harshness of the windswept rocks. This is one of my favourite conditions in Sardinian seascape and landscapes, where the opposites meet one another: soft and hard, bright and gloomy, vivid and muted. This kind of complementarity is one of the things I often search for.
Taking this photo didn’t require any specific technique; in fact, as for other similar cases, I’ve used a 10 stops ND filter to extend the exposure time, making the clouds movement more visible, plus a 2 stops graduated ND filter to darken the sky a bit. However, the thing that complicated the shooting has been the strong wind coming from the sea: this caused an intermittent spraying of seawater droplets on the filter, forcing me to clean-shoot-check-clean-shoot-checkagain. To make things worse, a 30 seconds exposure is a lot of time in a situation like this. As a result, due to the unsuccessful attempts and the time needed to clean and mount the filter again, just a couple of shots turned out to be really usable.
