Model-turned-photographer Helena Christensen is among the celebrities backing an international photography competition to raise money for a breast cancer charity.

The competition, called Renaissance, is judged by a panel that includes fellow photographers Eamonn McCabe and Mary McCartney.

The top prize is a 6-night trip to the Masai Mara in Kenya, while the runner-up will bag £500 in photography equipment vouchers from retailer Calumet.

The best pictures will go on show in a four-day exhibition at Proud galleries in London next March.

The contest was the brainchild of photography enthusiast Fiona Gifford who has recovered from breast cancer.

It costs £15 to enter a single image and £25 for a series of up to six pictures. Entries must be as JPEG files to www.renaissancephotography.org or London-photographic-association.com

Entries must be on the theme Renaissance.

Money raised will go the Lavender Trust at Breast Cancer Care and to raise awareness of breast cancer in younger people.

Also supporting the project are TV presenters Katie Derham and Krishnan Guru-Murthy.

The closing date is 10 December.
