Rummaging through some old files I found this - my photo on the cover of one of those booklets Hasselblad used to publish. This one was in 1980. They also used to use some of my pics on their posters.
I bought my first Hasselblad (500C) in about 1965 (later added 2 more). My first 6 books were shot with Hasselblads. I switched to 35mm when I did my first Alaska book in 1976 because I made a 13 day backpacking trip through the Brooks Range and the Hasselblad equipment was too heavy to carry.
Since I've gone digital they now sit on the shelf. I'll never get rid of them because even after 40 years of rough use in the boondocks they still work flawlessly. The finest precision cameras ever made, in my opinion.
