White Rock Beach on Killiney Bay is an extension of Killiney Beach, but is cut off from the main strand at high tide.
This swimming platform has been carved out of the rock, and is largely exposed at low tide. Taken here with a long exposure at high tide, it seems to be floating in a sea of mist.

The Muglins lie about half a mile northeast of Dalkey Island, and are a danger to shipping. Many ships came to grief on these rocks until a light was established at around the turn of the 20th century.
This image was made on a very fine night, and shows the northeastern extent of Dalkey Island, with the Muglins light beyond. On the horizon, the Kish lighthouse winks at us.
This is one of the images that I'm most happy with. It is simple, but there is plenty for the eye to wander over and appreciate - most notably the line of clouds near the horizon and the fine detail in the Moon's reflection. The sea is slightly smoothed as it was a long exposure - perhaps 15 seconds or so.
This is the second image I've made of this location. Slightly earlier in the night than the first, and in almost identical weather conditions, it adds colour which I felt was lacking in the original.
