I wonder why this was written, and even more so, why it was published. Beginners will be lost by page three, since the author assumes his readers already know the fundamentals. Accomplished photographers will be bored by page three, since the author discloses nothing new, and illustrates his disclosures with photographs that are, well, nothing special. On virtually every page there is another cryptic reference to the Zone System, but anyone up to speed on tone placements via Zone placements will be light years ahead of this book. Those who aren't will feel they're reading Esperanto.
