How to take long exposure pictures of the sea
01 Pick your location
Ideally you need somewhere where you can get down near the water as it breaks over the shore. You also need the sun to be low in the sky so it picks out the rocks. For all this information, try a program or app that lets you work out the best time, date and spot to head to. LightTrac, which costs £2.99 for iPad, iPhone and Android phones, is a good choice.
02 Watch the tide
It’s no good just turning up at dusk or dawn – you need to check the tides. As a rule, these shots look better if the tide is going out because this ensures that the wet rocks glisten, but you also need the water to be high enough to break against your chosen rocks. UK photographers can visit bbc.in/tide-tables to check the tides online.
