Dublin is a place of colour and charm, here the setting sun brightens up the sky over the River Liffey.

On the photography workshop we experimented with silhouettes of the famous skyline from this part of Dublin.

The colours and dark outlines of the city's buildings captured the atmosphere of the evening in the Irish capital.

Join Panoramic Ireland to photograph Dublin on one of our Dublin Photo Tours.

This week's Guess the Location comes from a more famous, and guessable location in Ireland.

Last week, plenty of you guessed right as the image being from one of Dublin's many bridges.

This week, the tower seen here is silhouetted against the sunset sky, it's a well-known tower in a very well-known location.

Can you guess the location? Answer in the comments below or ask for clues.

Silhouettes often make a useful tool in photography, strong lines breaking the horizon or the shape of a majestic tree outlined against the colour of an evening sky.

Silhouettes serve to show off the sky, the photographer exposing for the highlights rather than the shadows to allow the shapes of the subject to come into its own.
