there is a stark beauty in the images - sometimes very little says a great deal!
One of the bigger influences on Kenna is Bill Brandt (but I can't find any of his good landscapes online) - but I could certainly see Callahan as an influence on him as well.

Harry Callahan: The Photographer at Work is a quite nice book I got recently - which does just that - shows a lot of his work in the process of being made - contact sheets, notes, negatives etc (interestingly, it's the first book the Centre for Creative Photography has produced by making all the copy work with a Betterlight Scanning back rather than film transparencies...)
