The Amon Carter Museum here in town had a retrospect of Elliot Porters life work last year. His black and white was as good as the color work but there was not very much of it. The color prints were outstanding and most dye transfer prints. This is a method that is the most archival for color printing. Unfortunately dye transfer printing is a lost art as the material used is no longer produced. He was the first environmental color photographer to my limited knowledge. One of his sons gave a talk about what it was like to have Elliot Porter for a father and he shared his memories of traveling to the Glen Canyon area of Northern Arizona before it was flooded and it became Lake Powell.
