A collection of negatives of Derby Cathedral dating back to the 1880s has been found and developed.
They include two of the earliest-known photographs of the cathedral; one of the outside, taken between 1873 and 1880, and one of the nave from 1889.
The fragile plate glass negatives were discovered by a volunteer at W. W. Winter Ltd photography studio in Derby.
They were developed in Nottingham using traditional darkroom methods and are now on display in the cathedral.
