Picture power: Andy and Judy Murray

On Sunday, Andy Murray became the first British man to win the Wimbledon singles title in 77 years. Press Association photographer Jonathan Brady relives the moment he captured Murray embracing his mother on Centre Court, an image that was widely used in the press the following day.

As a photographer for the UK's national news agency I had covered the previous year's final between Murray and Roger Federer, which resulted in the Scot's first public emotional outpouring following that defeat.

I think every photographer knew going out on to Centre Court that if Murray pulled off a win we were all going to witness first-hand a historic moment. We would have to be on top of our game, just like the players.

From the semi-finals onwards, Centre Court photographic positions are assigned using a ticket system, so once you know where your seat is you cannot move from it. There are a certain limited number of photographers who are allowed on to the court surface after the finals to photograph the winners. My position for the men's final on Sunday was between the bottom of the royal box and the large scoreboard underneath the players' guest boxes.

Although it is not a position that allows the photographer to capture a wide variety of action shots, in comparison to the "pits" at courtside, it often provides the best opportunities to document the players' reactions, as they gesture towards their families.

Throughout the final, I shot around 1,500 images, of which roughly half were sent directly from the camera to the Press Association's onsite editor. Forty-four of the best images were uploaded to the wire and many were published in newspapers throughout the country.

At first I wasn't sure whether I had missed Murray hugging his mum. It was a rather messy scene up there and I was struggling to see over the tops of other people's heads.

I had followed Andy as best I could as he mounted the players' box area, despite the difficulty in capturing a clean shot.

I had some rather average frames of him hugging his coaching staff, before he returned to embrace Judy Murray, after initially forgetting to acknowledge her. I knew it was a massive moment because she has been such a huge influence on his career and as a "tennis parent" is relatively high profile.

Fortunately, my camera angle of the hug was not blocked by the top of the scoreboard and fittingly they embraced for quite a while. I had a decent amount of time to make sure I had several frames with her appearing to express different emotions. In this particular instance I remember knowing that I had definitely captured an image where she had a great smile. I can distinctly remember lip-reading her saying "I'm so proud of you" to Andy.

And then he was off and I checked the back of my camera and knew I had captured a special moment.
