Technical Film and TV for Nontechnical People

I teach high school video production ,I am electronics /computer hardware type I found this book really cool beacuse it covered things that I had never had to deal with before or even concepts that I never used before this book was so helpful to me I bought 2 more copies and gave one to my theater teacher (along with the "stagecraft "book by the same author) beacause I also do the technical A/V for school productions and I bought a copy for my industry partner beacuse we are buliding a web broadcasting studio for him this book was a wealth if inforamtion and I highly recommend it thanks
