Samir Hussein who took the umbrella photo said
"After speaking to Harry and Meghan's press officer, I learnt they would be dropped off short of the entrance to Mansion House and walk around ten meters before entering the event. I positioned myself in the official photographer's pen in the best place possible to capture the couple head on.
"As they walked towards me I noticed a flash going off from a camera in the crowd behind them. I knew that if that light could be lined up to be right behind as they walked then it could create a dramatic photo, acting like a back light in a studio shot. I managed to manoeuvre myself to line up the flash behind them and then had to work quickly, with just a second or two to get the shot, as they smiled wonderfully at each other. Immediately, I downloaded the photos onto my laptop and that image jumped straight out at me. I held my breath as I zoomed in to check if it was sharp (with the rain pouring and many flashes firing, it's easy to end up with soft images). Thankfully, it was sharp and I knew I had a truly special shot.
"I've photographed the royals for more than 12 years, but this photo really resonates. I've taken many photos I'm really proud of, but in terms of the huge interest in the subjects and the response I've had, this is probably the most iconic photo I've taken.
“It's a one in a million when all the elements you could wish for as a photographer come together – perfect timing, great lighting, strong symbolism and amazing subjects make this a magical photo I am extremely proud of"
But hey all GNers know more about it than he does.
