"Twenty years ago, images such as these would have been neither seen nor heard," he says.

He is referring to a unique and stunning photographic exhibition created by and about people with Down's syndrome.

The collection of pictures of babies, children and adults is on display at Dean Clough, Halifax – the first time it has come to Yorkshire after successfully running in London for the past five years.

The exhibition, Shifting Persp-ectives, challenges long-held stereotypes of people with Down's syndrome, presenting a genuine picture of those living with the condition.

The result is an uplifting and inspiring collection of images which features the work of six photographers, all of whom manage to skilfully and tenderly portray a very personal view – they all either have Down's syndrome themselves or have a child with the condition.

One of them is Richard Bailey, whose daughter Billie-Jo is almost 10 and who features in the collection.

Billie-Jo was born with Down's syndrome and Richard, a professional photographer, says the early days were difficult.

"I admit when she was born we didn't know how we were ever going to live with her, with a child that was 'different.' But almost 10 years on and we have this wonderfully funny, clever and beautiful daughter with an infectious laugh, a wealth of friends and an ability to charm people wherever she goes. Now I have no idea how I could ever live without her," he says.

The idea of the exhibition is to celebrate this positive message, that people with Down's syndrome can lead a fulfilling and rewarding life.

As a result there are images of children at play, of young people taking part in sporting competitions – including those who represent their country at the Special Olympic World Cham-pionships – at their studies and at work. One young woman smiles broadly back at the camera, smartly dressed in her chef's whites. The caption underneath explains how not only has she won medals for her gymnastic skills but she is now assistant chef at one of Cheshire's top restaurants.

Religions is another topic with photographs of people from all different faiths and cultures.

"There are a number of myths to dispel!" says Richard.

"People always ask if Down's syndrome exists in every race because they believe that it doesn't. But yes, all generations, all races, all religions and all economic situations are affected. It doesn't matter where in the world you live."

The images in this section include a beautiful photograph of a Jewish family about to sit and eat their meal, the ingredients arranged on the table along with brightly shining candles.
