But experts caution the growing popularity of the role has also attracted newcomers to the industry.
Thorne said the “relatively low barriers to entry” meant some people could try and do the job, despite having little experience of working at weddings.
Urging couples to check experience and credentials, she said: “A lot of people, while they might have relevant experience, such as working in social media, they’re not experienced in wedding delivery.”
Back at the wedding, Burton is weaving between tables and scanning the room for reactions she might otherwise miss.
She is keen to challenge the idea that the role simply involves pressing record on a smartphone.
“I think there’s more to it than meets the eye. You have to have a good eye for composition, lighting, storytelling. Anticipating moments is really important.
“There’s one take of the ceremony – you can’t miss it.”
