Mike - it is a very technical book, but if you read it in sections then go back and refer to stuff you need later on it’s a bit easier to take in.

I learned a huge amount about HDR from the book and a large amount of the gaps in my knowledge have been filled. I now keep it as a reference book. I am confident about realistic HDR editing now and it doesn’t take very long any more either. It’s all about preparation when on-site.

Also, thanks to this website, as I found out about this book from here!
