Hello! For over 25 years I have consulted and taught on the topics of digital photography, workflow, image backup, printing and color management for individuals and corporations. I served as Editorial Director of Digital Imaging Techniques magazine for two years, where I wrote and edited numerous articles and reviews on the topics of digital and fine-art photography, inkjet printing, and Photoshop techniques. I've also conducted seminars across the United States at photo-related conferences including the Arles Photo Festival (Arles, France) and the PhotoPlus Expo (New York City), and have lectured and/or taught at institutions including Columbia University and the International Center of Photography (ICP) in New York City. My photography has been exhibited in numerous group and solo shows, and my work has been included in many photography publications. I'm the editor and founder of The Imaging Buffet Digital Magazine (https://imagingbuffet.com) and I publish a Photo Tips Newsletter, which includes tips and techniques related to fine-art printing and digital imaging. I've written four books (all related to photography), and my Amazon Author page can be found here:
