That title just offered itself up. Elementary Telephotography by Ernest Marriage (1901) may be the first book on the subject [10 mins. later - not quite true - Dallmeyer wrote a book although mostly about the physics of telephotography], although articles have been written some time before the publication. Chapter 3, after the first two were devoted to the construction of telephoto lenses, gets into the fun stuff. Notice the words "snap shots" in there? I wonder what snap shots meant to photogs back then. source
As expected, telephoto lenses were used for similar reasons as today. What about this shot? The early Paparazzo?
Using a hat to screen incoming light? Been there, done that.
Hey, this cow dude is wildlife to me. :)
