Wow, all right. That may be the reason some artists may have found the book full of legalese. In my humble opinion, this is a must-have for anyone that claims oneself to be one of the ones listed above. If not this book, what else?
Starting from the minute one decides to have some "interaction" with other human beings regarding the making (or selling) of one's art, this book is of big help. For instance, an artist may decide to hire a model to paint a picture, this book will guide him/her how to prepare a model release form in order to guarantee the artist benefits of the painting created, without problems such as violation of privacy in the long run. This book is also a critical line of defense for the artists in dealing with copyrights, ownership, insurance, and tax income, etc.
My guess is that if one is simply an artist, one would read through the book (or at least sections of immediate concern, for instance, a painter would not have to worry too much about sections for photographers) and scan through the whole book for information. As far as using the book on a regular basis, I believe by frequently reviewing relevant sections, as well as making use of sample forms provided in the book, any visual artist will find this book an indispensable tool for his/her art making/selling process.
Strongly recommended.
I'm buying my own copy since I basically trashed the studio's copy -- it's helpful enough that you'll use it on an ongoing basis.
