The artist behind one of the final four artworks under consideration for the Turner Prize has said her nomination is recognition of what the piece is about.

Helen Cammock's The Long Note celebrates the role of women in Northern Ireland's civil rights movement.

It was commissioned to coincide with the 50th anniversary of a civil rights march in Londonderry.

Cammock said her nomination was an "incredible platform" for her work.

"It is absolutely amazing, it is recognition not only for me as an artist but for what the piece is about, that's the most significant thing," the artist told ����ý Radio Foyle.

"It is really important for the film. It is an incredible platform, a way of sharing my ideas and thoughts and the things that are in the work."

Nominated alongside Lawrence Abu Hamdan, Tai Shani and Oscar Murillo, Cammock's work is now on show at the Turner Contemporary in Margate.

The Long Note, she said, "weaves its way through the stories and voices of women from Northern Ireland".

The collage features archival footage, new film, text and interviews and was first commissioned by Void Gallery curator Mary Cremin.

"We wanted to commission a film about women and the civil rights movement," she said.

"We thought it was a history that hadn't really been spoken about or written about."

The Turner Prize nomination brings the work to a whole new audience, she added.

"It is one of those exhibitions that is really owned by the public and the public is really engaged in going to it. For them it really reflects what is going on in the UK at a certain time.

"A lot of people don't know about the civil rights movement in Northern Ireland or the context of it. I'm hoping it really makes people think about the history," she said.

The Turner Prize winner will be announced on 3 December.
