During all my film work, I carried a camera wherever I went, and continued to take a lot of stills, as we call them. And had such good chances like photographing Nehru and other heads of state like Beneš, a Czech president who had his government here in London during the war and others. Of course Julian Huxley and Sean O'Casey I photographed a lot, and got very friendly with him and his family. And my photographs found appreciation and in 1982 it was, I had my first big exhibition here in London at the Photographer’s Gallery, which was then run by Sue Davis, a wonderful woman who did a lot for photography in this country, and is still active. I subsequently had other exhibitions. I published children’s books, photographed in... in colour in those days, which was rather early colour. The most known one was called That Baby, about a young boy who expects a sibling, and it was made by... with the help of a psychologist who worked with Anna Freud, and was found very useful by parents who wanted to introduce the problem to their young son, or daughter. There were other children’s books — alphabets — and later I did a book in ’57, I believe, with Julian Huxley writing the text, about animals. That was mainly, it was called The Kingdom of the Beasts, published by Thames and Hudson, long out of print, unfortunately. In those days it was very difficult to get photographic books published because-it was a very expensive process. Photographing was the best, but you had to have an edition of about 20,000 to make it pay. I subsequently had exhibitions in Amsterdam and in Vienna, and a book published a couple of years ago in Vienna, in two languages, which is still about. I think most of your photos have been black and white, haven't they? Most of my pub... yes, my most... all my photographs exhibited or published were in black and white, except the early children’s books, and... sorry. Do you prefer it? I prefer it, and I never learnt how to print colour. I did all my own printing for exhibitions, and the pictures in my last book were all scanned from my prints.
