After 18 years respite from photography I have recently started looking through a lens. This evening I seached my bookcase and browsed Mr Pickers dog-eared book Zone VI Workshop, 8th printing 1979 , this book was my constant as I learned the Zone system. I still have a couple of letters and my first lens/camers calibration results from Mr. Picker. As I sat this evening with the excitment of returning to my old hobby it occured to me that I may get up-to-date information on Mr. Picker and the Zone VI Studios - I did. I did not know him other than his work and the inspiration he gave me but somehow I feel the loss of an old friend. Peter Corbett - London 8th May 2002
