The Camera On series is unique for modelers in that it not a specification/tech manual for the subject under discussion, it is a pictorial study with pictures taken directly from archives and the original prints and detailing visually the subject in question. In this case, the subjects are Luftwaffe Search Lights and Range Finding Equipment, Volume 1.
As an overview, the book contains dozens of period pictures of search lights and range finding equipment in various forms of use. The pictures are WWII period and are all black and white. From the foreward, Alan Ranger explains the goal is o present the pictures of the equipment as taken by the German soldiers not professional photographers. The goal is to get the feel and way of life of the soldiers that manned these batteries. This includes wonderful shots of the men manning their machines and the installations. Not only are search lights included but the Luftwaffe range finding equipment is included with explanations.
