Small fishing weights were attached to the dresses

The shoot was carried out over three days in July with a huge crew of 15 models, photographers, videographers, safety divers, logistics managers, lighting assistants and air providers working between 5.30am and midnight every day to capture the perfect shot.
Sharon said: 'Obviously, the fact we were shooting in the depths of the sea rather than in a shallow water pool introduced us with some unique challenges, which made the end result so much more worthwhile.
'For instance, when shooting in a depth of 20 meters, there is no way a model can descend over and over again by free diving and still have enough air to allow for a few photographs to be taken before she ascends again.'The three models featured in the shoot needed to be experienced scuba divers and were tied with fishing lines attached to weights to keep them in place.Kids dress up as fairy-tale characters, superheroes for Missoula festival.
A dedicated 'air provider' diver was assigned to each model to give them enough air from a scuba tank so they could hold their breath for a few seconds as each photo was taken.
A number of other divers were also needed to supervise the models and make sure they did not fall or become entangled while the shoot was taking place.
Small fishing weights were attached to the dresses to keep them buoyant and create the best effect and special underwater housings were used to keep the camera equipment dry.
Sharon said: 'The model goes through a lot during a project like this. First, she's wearing nothing but a wedding dress so her body temperature rapidly decreases, making it difficult for her to keep a natural look and to hold her breath during the shots.
'Secondly, she isn't wearing a mask and so her communication with the divers around her is very limited.'In fact, the only diver she can really communicate with is her air provider, who is the only one close enough for her to see.
'The model has to hold her breath for quite long periods, which becomes more difficult the more time she spends underwater and the lower her body temperature gets.
'And, as if that's not enough, she's also tied with weights to the bottom of the sea, which doesn't add much to her sense of confidence. Great trust and magnificent water skills are required in order for a model to remain calm in such a setting.'
