This 19th-century photograph, "Fotoreproductie van een gravure van Convenanters Preaching," by Thomas Annan, is a photo-reproduction of a print after Sir George Harvey's painting. The work depicts a scene from Scottish history, likely portraying a group of Covenanters, Scottish Presbyterian Protestants, preaching in the open air. Annan, a pioneer of photography in Scotland, used a calotype process to create this image, revealing a detailed and atmospheric representation of the original artwork. This photo serves as a testament to Annan's skill in capturing the essence of another artist's work through the medium of photography.
