A collection of unpublished photographs from Captain Scott's Terra Nova expedition sold for ?�30,000 ($44,794) at Henry Aldridge & Son auctioneers on April 18.
The archive shows scenes from the ill-fated voyage, which resulted in the death of Scott and the four men he led into Antarctica's interior in 1912.
Andrew Aldridge explained: "The negatives offer an incredible snapshot into one of the most famous British Antarctic expeditions of the 20th century.
"They show the brutal nature of the environment these brave men went on to endure. The clarity of the images is truly remarkable and includes previously unseen elements including the polar party marching, pitching tents and them having lunch.
"The vast majority of Ponting's pictures are in the Scott Polar Research Unit. As far as we can tell most of these negatives haven't been published before."
The auction follows on from the sale of a large collection of negatives from the mission last year. The University of Cambridge's Scott Polar Research Institute raised ?�275,000 to ensure that the archive stayed in Britain.
Another set of Terra Nova images will cross the block at Christie's London on April 28.
