As someone living in the middle of the European continent with more than 300km aerial distance from the closest coastline, seascapes are a rare opportunity for me.
While the principles of landscape and seascape photography stay the same, planning photos differs a lot. At the coast, not only does the weather, sunrise and sunset play a part, but also the tides and waves. Low or high tide can completely transform a scene and the right wave with the right exposure time can make or break a composition.
Both world provide their own distinct features but also dangers. I am lucky to never have lost any gear to the sea, even though I have been caught off-guard a few times by a sneaker wave.
