Research profile

Scientific interests of Assistant Professor Dr Piotr Nowak originate from the tradition of Phototechnology Department, where properties and structure of photographic images were investigated. In his investigations, he modified and improved the standard algorithms of optical granularity estimation, and modulation transfer function for the silver halides photographic materials and other materials. His recent investigations concentrate on the preparation of silver halogen emulsion using polar aprotic organic solvents.
