This book is all about Photo Interpretation (PI). However, it's not about the esthetic qualities of photographs, nice as they may be. PI is a quantitative analysis of a photo where you measure things and do some calculations to derive all kinds of valuable information, stuff you probably didn’t realize you can get off of even the simplest photos.
Before getting into the calculations there's a brief review of the history of taking photos from above followed by a much more complete history of cameras designed for model rockets.
If you're not up-to-date on your trigonometry basics, there's a helpful primer at the end in Appendix A.
Finally, Ted Mahler tells a story of how hard it is to actually take a photo of a specific target from a model rocket as a report on his "Target Photography" Fun Event at NARAM 36.
