Daniel Hartz has been a freelance photo designer for twenty years. He specialises in still-life photography. Today his international work, managed from his studios in Hamburg and Stuttgart, has a particular emphasis on transportation. Over the years the perspectives change, but so does the technology – sometimes significantly.Three years ago he helped found ViewMasterCGI, a company that specialises in photo-realistic visualisation of products such as cars. A lot of pioneering work was required since the technique had already been used in a similar form in the film industry, but not yet in such a high-resolution form as that required for prints. The classic photographer profession is on the brink of change. As with typography a few years ago, the starting point is the change in technical resources.
