I found this book randomly the other day at Indigo and am so glad that I did, because the information in it is pure gold.
Where other books have you drawing boxes in perspective then leave you stuck at what to do with more complicated subjects, this book really helps you to see, understand and apply perspective to much more complicated architectural forms. It gives many photographic examples, along with artistic renderings of those photographs, so that you can really begin to see and break down the construction of your drawings.
It also emphasizes the fact that your drawings don't need to be extremely accurate and tight, which is something I was struggling with while trying to use a ruler to form all of my lines. It also encourages you to estimate convergence of lines that have vanishing points off of the page.
The section that sets this book apart from every other perspective book is that it actually covers multi-point perspective in detail. This was a concept that I had difficulty understanding initially because other books only covered 1, 2 and 3 point perspective, which left me confused as to what to do when trying to draw objects with angles that didn't converge at those points.
I also found the section on curvilinear perspective to be really interesting. This is another perspective that is not commonly discussed in other books. Hopefully one day I will be good enough to try and attempt it.
The only things that I found lacking here were that it didn't go into much of any technical detail about crucial construction topics, such as constructing ellipses in perspective, the importance of dividing areas, creating inclined planes, describing the cone of vision, horizon and station point and understanding object distortion. That's why I think this book is best paired with a more technical book for understanding those topics. However, since I already had knowledge of those topics from other books, I really didn't mind.
Another neat thing about this book is that it comes with downloadable perspective grids to use and has a cool workbook section in the back.
