At the beginning of the nineties, Di Renzo leaves Italy to have first experiences in the field of fashion photography. Amongst others, he works in Istanbul for fashion magazines such as Harper’s Bazaar and Elle. In 2001, Di Renzo returns to Switzerland for a short time to work as an advertising and fashion photographer. A few years later, his work draws the attention of fashion designer Tsumori Chisato who commissions him for an international campaign as well as a store concept. During this period, Di Renzo – who in the meantime has moved to New York/Los Angeles – takes up work on his first book of photographs, „Portraits of Illusions“. The photo book tells short stories with pictures taken, amongst others, in Ireland, New York, and the Seychelles. The photos intentionally drift away from reality - Di Renzo’s motto being: Move away from Realism. The book is published by Assouline in 2006, with a preface by critic Gabriel Bauret. During this time, Di Renzo works with, amongst others, Devon Aoki, Chloë Sevigny, Natalia Vodianova, Dean&Dan (DSQUARED).
