The British Geological Survey houses the National Archive of Geological Photographs (NAGP), comprising in excess of 100 000 fully-described earth science images. Of these images, 22 000 are captured on glass plate negatives.

The archive is part of the BGS's photographic services department which, since its inception over 100 years ago, has supported the scientific work of the Survey.

Some of the NAGP is available to view and download at GeoScenic.

The NAGP is one of the best collections of geological and associated imagery in the world and is certainly one of the oldest

— but where did it all begin and why?

In order to understand this, we need to examine the roots of the photographic revolution that swept the world in the nineteenth century, the early experiments and technique development.
