dslr lenses- get to know all about telephoto, prime lenses, wide angle and kit lenses! Which to use for faces, which to use for places, and everything in between. (great info for beginner photographers)
I don't know when I would ever use this, since I don't do product photography, but it sure is a good idea! Might come in handy someday. Digital image on the monitor as a backdrop and product sitting on the shiny surface of a book! Pretty creative.
