Still, I was able to find out more than I can use in the field of Presenting a Design-Tech Portfolio.
I thought of this as maybe going into a second career. Now I am not sure. I had to stick close to the glossary of this book.
Not familiar enough with the subject I did not have to unlearn anything. However, I have nothing to compare this book to.
A little side note is that the information in this book helped me to better view the DVD extras where they describe the original design notes and sketches for plays and movies alike.
