Up to 327 million pictures will be taken of next week's wedding of Britain's Prince William and Kate Middleton, according to a new poll. A survey carried out by Nikon found that of the hundreds of millions of royal wedding photos taken on digital cameras, the most sought after image will be the first appearance of the pair as a married couple. The second most sought-after royal wedding picture will be William's and Kate's kiss on the balcony of Buckingham Palace after the ceremony. The Nikon survey also found that some 65 million royal wedding photos will be shared online through social media websites. To celebrate the Royal Wedding, Nikon has teamed up with Arthur Edwards, royal photographer at The Sun, to give some expert tips and tricks on how to capture the big day.
