Adrian Ensor has been developing and printing photographs in his London dark room for over forty years. He has worked with artists such as Hamish Fulton and Richard Long as well as more recently printing his own photographs.

After visiting The Radical Eye exhibition of Modernist Photography at Tate Modern Adrian sat down to talk us through the subtle and delicate process of developing, exposing and printing photographs on gelatin silver paper.

The gelatin silver process was introduced at the end of the nineteenth century and dominated black-and-white photography in the twentieth century. The paper or film used to make gelatin silver prints and negatives is coated with an emulsion that contains gelatin and silver salts.
