Right,
I've been through all this only over the last 6 months. I too wanted a book, or books, that told me what to do because I wanted to get straight in there and play. STOP NOW
Get "Light. Science & Magic" 3rd Edition 2007 ISBN 13: 978-0-240-80819-2 by Fil Hunter, Steven Biver, Paul Fuqua. and READ IT. DO NOT assume that because the initial pages have simple diagrams explaining how light works (and you, like like me know this already, don't we?) we acutally understand how light works for photography.
I started out, like with so many technical books whose value I question, just dipping in to see if they had anything new to say. In actual fact, probably for the first time in years I went back and started from the first Introduction and read the whole book page by page, cover to cover. There were things I knew, things I thought I knew (but not quite) and new things.
If I have a failing, it's to buy books on subjects that interest me; most of which I skim. This book makes you really think about LIGHT and how it works.
Look, if you really want to understand lighting and photography (rather than be given other people's setups) buy it, READ IT and don't just dip in, but start with the introduction (these guys aren't wasting words) and go through it page by page. OK
