I was very far away from the people in the photograph and there was a degree of camera shake which result in some blur.

Actually the man is using a tennis racquet to propel tennis balls into the Irish Sea for the dog to chase and recover.

Seapoint is a small seafront area between Blackrock and Monkstown in Dublin in the Dún Laoghaire–Rathdown area. It is best known for its beach and bathing areas, beside a Martello Tower on the Dublin Bay seashore. The beach currently has an International Blue flag award and a national Green flag award.

The Martello Tower is now the headquarters of the Genealogical Society of Ireland.

The route linking Dún Laoghaire harbour to the N11 National primary route has itself been designated a National primary route, the N31. Part of the route includes Seapoint Avenue, and the Seapoint area is located on the strip of land, which includes the railway line, between the road and the sea.
