The National Portrait Gallery has just reopened after three years of redevelopment. One of the first temporary exhibitions features the photography of the enormously influential Yevonde (1893-1975, seen here in a 1937 self-portrait). Madame Yevonde, as she was also known, was a pioneer of colour photography who made her name with highly styled, glamorous portraits of society women and celebrities. As befits a member of the women's suffrage  movement, she rejected the demure romanticism of Edwardian studio photography and developed her own experimental and unconventional style.
