According to legendary racer Kevin Sanders, the exhibition features pictures which were taken during the rally across Russia.
Among them are images of a Buddhist datsan in Buryatia, Lake Baikal, etc.
This is already the second photo exhibition dedicated to the rally. The first one took place in Yekaterinburg and featured 40 photographs.
St. Petersburg will host the main exhibition with some 100 photos as soon as the rally is over.
Rally organizer Lord Nicholas Fairfax said that the rally would finish in St. Petersburg on June 12. A special ceremony will be held to greet the participants.
A reception in their honor will take place in the Sheremetyev Palace in the evening, with St. Petersburg governor Valentina Matviyenko attending.
According to Fairfax, he will not organize similar rallies in other countries in the near future.
This is a special Russian project, he said adding that he had visited Russia throughout 20 years.
The White Nights Rally is a major charity event initiated by British aristocrats. It started in Vladivostok (Russia's Far East) on May 2.
All in all, the project collected about $1 million for charity purposes.
The photo exhibition will be running until June 14.
