are 125-year-old images depicting life on St Kilda and the Western Isles in the 1800s are to be unveiled to the public.

The iconic collection was taken by Aberdeen photographers George Washington Wilson and Norman Macleod who embarked on a journey from Oban to St Kilda in 1886.

The images were captured on individually hand-coloured lantern slides which were produced 50 years before colour photography reached Scotland.

They will be shown at the event in their original format using a Victorian magic lantern projector.

Author and historian Mark Butterworth, a leading expert on the photographic lantern slides of Scotland produced during the 19th century, will present the slides at the event, which is part of the University of Aberdeen’s Café Scientifique series.

He said: “The incredible journey taken by George Washington Wilson and Norman Macleod as they travelled through the Western Isles of Scotland to St Kilda is portrayed beautifully in their images, which uniquely capture the way of life in the 1800s in evocative detail.

“I acquired these rare hand-coloured slides in 2004, complete with the original accompanying lecture notes and have since given regular presentations, sharing this unique collection of rarely seen images with the public.”

The free event will take place in Aberdeen’s Waterstone’s at 7pm on Wednesday.
