I ordered both the Big Island and the Kaua'i versions of "Hawaii Dreamscapes Revealed". (I have been to both islands.) The major reason was that Andrew Doughty, author and co-photographer (with Leona Boyd) is the author of the best guidebooks to the Hawaiian Islands, also published by Wizard Publications. My opinion of both books is very similar, so I hope you will excuse my repeating much of the text in my two reviews.
The Big Island is the youngest, and the one where volcanism is still shaping the island. It is also dominated by two towering peaks (Mauna Loa and Mauna Kea) not yet eroded by time and weather. So you can go from snow to lava in a matter of hours. While there are lush areas on the island, there are also stark landscapes.
The pictures are generally well done, but give a sense of "I could have taken that picture if I was in the right place at the right time". (In fact, I've taken some pictures as good or better on the islands, but few people will have the opportunity to spend the time it takes to cover a whole island with enough revisits to get cooperative light and weather everywhere.) There are very few breathtaking, "I couldn't have done that" shots in the book. In fact, some of the pictures are not very interesting, or have technical flaws. The book could probably have been 20-30% shorter while being better from an overall photographic standpoint. Doughty's captions are short and serviceable, but having his guidebook for context will help if your interest goes beyond looking at attractive landscapes.
If you like picture books and want either something to remind you of the Big Island or to help plan a trip, this is a decent book. I was careful to order when Amazon had it at the lower end of the price yo-yo they seem to like to put it through.
