I recently got a book 'Images of the Seventh Day' by Michael Kenna. Highly recommended, by the way.
I'm particularly interested in his minimal black and white landscapes and it's similar to the kind of look I strive for myself.
Looking through, I saw the image below, "Log and Plane, Florida USA, 1992" and I was intrigued as to how he might have achieved it.
Being 1992, I'd doubt much digital PP was involved. But other than that I'm quite clueless.
Just as an intellectual exercise, if you feel like an educated-guessing game, I would love to hear your ideas.
