Busbridge-based Glenn Harvey, 53, is behind the exhibition, called Diana: A Princess Remembered, which features 100 portraits.
It has been running in Japan since November and will go to India in May.
The special collection of large format photographs of the late Princess of Wales was staged in association with the British Council to promote cultural relations between Japan and the UK.
The centrepiece of the exhibition is the famous and poignant image of the lonely Diana in one the most romantic settings in the world – the Taj Mahal.
Mr Harvey’s photographic work has so far been displayed in 11 cities across Japan and visited by almost 200,000 people.
The images are rare and from the photographer’s private collection of prize-winning photographs, taken as Diana travelled the world.
“I first met a young Lady Diana Spencer when rumours first began about a romance with Prince Charles”, said Mr Harvey, who worked as a Royal photographer from 1985 until the year of the Princess of Wales’ death.
“We were only a year apart in age but from very different backgrounds.
“This exhibition celebrates her life and showcases her transformation from a shy Pimlico nanny to the global icon she became.
“Many of the photographs are informal, some fun, but all demonstrate the best of what Diana represented as a great humanitarian and British ambassador.
“Her sparkly personality shines through in every picture and I feel very proud to be able to pay my own personal tribute to her.”
The exhibition tour also raises funds for one of Diana’s charitable causes Landmine Action. It was established to co-ordinate UK campaigning against anti-personnel mines.
The charity was renamed Action on Armed Violence (AOAV) in 2012. It works with communities in Burundi, Sierra Leone, Liberia, Western Sahara and Nigeria affected by armed violence, removing the threat of weapons, reducing the risks that provoke violence and conflict, and supporting the recovery of victims and survivors.
Mr Harvey, who has taken part in more than 150 royal tours, still works taking photographs for magazines and papers and specialises in bespoke home portraits, school proms and theatre and drama groups.
