I've bought the book as well, and it is a real pleasure to look at this quality level photography as well as printing.
If this Rangefinderfreak has any close insight into his technique, I would be certainly interested to get a glimpse. It looks, like he is using mainly medium format cameras, exposing generously and using a yellow filter often.
What is amazing, is that if you start factoring in the exposure, filters, nice depth of field, etc, it turns out like he must be shooting a lot from a tripod. Yet, many of these photos look very spontaneous, and there are certainly several great decisive moments captured.
