A new exhibition which showcases the development of fine art photography in Scotland has opened.

In Focus: Scottish Photography launched at the City Art Centre in Edinburgh at the weekend, featuring 50 historic pieces.

Some of the photographs date back to the 1840s, standing in stark contrast to the vivid images of today.

Edinburgh played a key role in the development of Scottish photography as an art form, with artists David Octavius Hill and Robert Adamson emerging during this time.

The exhibition will also feature at the Edinburgh Art Festival on July 26.

Curator Dr Helen Scott said changing technology throughout the ages had shaped the art.

She said: "It used to be a much more laborious process, when you're producing calotypes or using the west collodiun process.

"Some modern day photographers still use these techniques.

"But today a lot of artists are also incorporating digital technology which is much more widely available."
