This is a beautiful book, well done. I can't read dutch, but as the drawings and the photographs are of a great quality, it's a real pleasure to flip through this book. To the point where the will to be able to understand the text is really big.

The about 40 pages on kap history is well documented, and followed by examples on this technique use.

The technical pages look very interesting, as seen from the drawings. The most remarkables are in the last chapters, with graphic and geometric considerations on aerial perspectives of buildings, trees, and on the projected shadows.
