Christian Vogt has been working with photography for nearly fifty years. His ongoing dialogue with the medium has repeatedly given rise to a new image language, often putting him ahead of his time. Vogt's work can be regarded as an exploration of vision: for him, an image is always a projection screen, as each observer reacts differently to what is shown. Christian Vogt: The Longer I Look is the first monograph covering the entirety of his oeuvre. Some 350 images offer a comprehensive overview of Vogt's conceptual work, his philosophical inquiries, and his capacity to visualise the 'things behind things'. The book also features a brief introductory essay by Vogt himself and a conversation between the artist and curator Martin Gasser.
