Trust, but get it in writing
I recently came across a book titled The Basic Beginner's Guide to Photography, Light and Exposure co-written by Scott Bourne and Richard Harrington. It's available on iTunes as an iBook.
When looking at the preview in iTunes I recognized something familiar so I bought the book. It's only $0.99.
I thought that the treatment of basic exposure, camera controls, and metering presented in the book was very good. I would think that since I actually wrote most of it.
I met Scott Bourne back in 2001 and soon after began working with him on his fledgling Photofocus Magazine. I wrote many articles for that magazine.
Back in 2004-2005 I also wrote a series of short articles for what I called my "Back to Basics" series, which was meant to go on the Photofocus site (frankly, I don't recall if we ever published it there).
But in 2005 we co-authored 88 Secrets to Wildlife Photography, which included those articles.
I thought that this bit of writing was some of my best as well as being a pretty darn good explanation of the mechanics of exposure. So much so that it's been on my website for many years now. You can read the entire series here.
When comparing my Back to Basics series (as well as the Exposure and Light section of 88 Secrets to Wildlife Photography) to The Basic Beginner's Guide to Photography, Light and Exposure, I see that much of Chapter 3 of that book is taken word for word from what I wrote.
Since Scott and I co-authored 88 Secrets to Wildlife Photography and we didn't have a contract outlining rights of subsequent usage, he has every legal right to use that text. And even though he has this right, it's still rather annoying to me that my original work is now being passed off as someone else's.
Placing trust in someone is wonderful, though sometimes foolish. But a contract is even better. Lesson learned on my part: If ever I co-author another book there will be a contract outlining rights of subsequent usage.
