Inspired by Mary's book The White Horse, which captured the beauty of her white stallion Alejandro, we visited some of the last shire horses of Hampton Court for the shoot.

Three campaign images were turned into a very limited run of Mary McCartney prints, with profits from the print sales going to "Real Horse Power" – an Operation Centaur collaboration with Mind, which provides Equine-Assisted Psychotherapy for youths.

The C-type prints were printed on Fuji crystal archive paper and processed with Fuji chemistry. Fuji’s production processes operate exclusively on wind energy and they also generate their own energy with five wind turbines and a large afterburner. They have also pioneered a water purification plant with adjoining companies. The silver residue and by-products of the photographic process are valuable raw materials so they are extracted and recycled after the prints have been made.
