I’ve been blogging for some time now and have written mostly about how I have gone about running my photography business. In that spirit I would like to point you in the direction of this book: Best Business Practices For Photographers.
Full of great info from the perspective of assignment work. Even if you’re a newbie this book is a great reference guide, full of advice, case studies and samples of contract, invoices and licensing agreements!
I highly recommend this book be added to your growing library.
